1. SPECTRUM MONITORING DESCRIPTION TCI Model 700-series Spectrum Monitoring System (Scorpio) provides a compact, fully integrated

system, for monitoring and analysis of radio transmission. Depending on the configuration, frequency coverage is from 20 MHz to 3 GHz; or optionally from 9 kHz to 3 GHz.

Scorpio can operate in various configurations ranging from a single site, mobile or fixed, to a nation-wide network with multiple operators tasking multiple fixed and/or mobile systems. This capability is achieved through the use of Client/Server architecture, and through built-in networking capacity. Network communications between clients and servers are established using industry standard TCP/IP protocol.

In a basic configuration, the TCI Model 700-series consists of one Scorpio Measurement Client (Scorpio Client) and one Scorpio Measurement Server (Scorpio Server), shown in Figure 1-1. In this configuration, the system can be installed in a vehicle, or at fixed site.

Figure 1-1 Basic Configuration Block Diagram

1.1 Spectrum Monitoring Client (Scorpio Client)

Scorpio Client is a software application that requires a computer with a Windows operating system. This software provides an operator with an interface to the measurement Server (Scorpio Server). The interface includes all functions necessary to request measurements and to receive and analyze the results.

A task calendar, included in the software, allows the operator to schedule multiple measurements in the future. With this method, the communication between Scorpio Client-Server are needed only when measurement is being scheduled, or results are being retrieved. Once Scorpio Server has accepted Scorpio Clients’ tasking, it will execute the required measurements, and store the results. It is up to Scorpio Client to retrieve the results for the requested measurements.


1-2

This approach is well suited for systems where the communication link between Scorpio Client and Server is intermittent, as in the case of network communications via cellular phone links. 1.2 Spectrum Monitoring Server (Scorpio Server)

The Scorpio Server consists of a software application that runs on a TCI Spectrum Processor. The Spectrum Processor performs the entire signal processing using digital signal processing (DSP) technology. The Spectrum Processor is a VME based system with an embedded PC/AT controller, DSP processor, A/D converters, VHF/UHF RF downconverters and ancillary equipment. The frequency coverage of the Spectrum Processor is 20 MHz to 3 GHz and it can be extended down to 9 kHz with the additional TCI Model 8412 RF unit.

Scorpio Server software was designed for unattended operation, and automatically initializes and starts operation when power is applied. Scorpio Clients access Scorpio Server resources through LAN/WAN connection using the TCP/IP protocol. Scorpio Server allows multiple clients to time-share server measurement resources. All client requests are entered in Scorpio Server calendar, and executed at the requested time. In the event of scheduling conflicts, the Server resolves them as described later in this manual.


2-1

2. SCORPIO CLIENT BASICS The Scorpio Client software operates in different ways depending on the state of the network

connection to a Scorpio Server. When a Scorpio Client is not connected to a Scorpio Server, its operation is limited to review of the measurement results that have already been retrieved from a Server. Once Scorpio Client is connected to a Server, it can request new measurements and retrieve the results.

The Scorpio Server software provides two network connections, one for the "Interactive" mode, and the other for "Scheduled" measurements. A third network connection is provided by the Windows operating system, which provides time service between Scorpio Server and Clients so that the applications are synchronized.

2.1 Client-Server Connections – Scorpio Server

Scorpio Client software connects with the Scorpio Server in two modes:

• Interactive mode

• Scheduled mode

These two modes support all Clients’ signal monitoring and measurement activities.

2.1.1 Interactive Mode Interactive mode allows direct interaction with various functions that provide instantaneous feedback

such as monitor receiver tuning, demodulation selection and pan-display selection. Scorpio Server software allows only one interactive Scorpio Client connection at a time.

2.1.2 Scheduled (Calendar) Mode When Scorpio is used in Scheduled mode, a calendar feature in Scorpio Client will attempt to reserve

time slots on Scorpio Server for each measurement the operator schedules. A single Scorpio Server is able to handle requests from multiple Scorpio Clients.

If more than one request for a specific time slot is received by Scorpio Server, the request will be handled in one of three ways, depending upon the type of request and its priority:

• Bump the request already scheduled in that time slot. If a request with a higher priority, such as Pushbutton DF/Metrics, Homing DF, or Netted DF, is scheduled at a time

• Be scheduled into the closest time slot +/- 5 minutes.

• Be returned to the operator with an error message.

Note: A higher priority task, such as Pushbutton, Homing or Netted DF, will bump any lower priority tasks already scheduled into the same time slot. When all time slots are filled, the scheduling requests will be refused.


2-2

2.2 Scorpio Client-Server Connections- Windows Time Service

The time on Scorpio Client and server must be synchronized to provide (calendar) scheduled events. This is achieved by setting Scorpio Client computer time to Scorpio Server time via the Daytime service available under the Windows operating system.

2.3 Introduction to the Scorpio Client Software

The Scorpio Client application is of a modular design developed for use in many different environments and system configurations. Features are enabled or disabled dependent upon what options have been included for your organization.

This Scorpio Client Software Users Guide has been written to discuss all of the possible features of the Scorpio Client application. Menu options, Taskbar features, and Dialog boxes will change, be enhanced or restricted to accessing only options that have been included in your specific system configuration.

2.4 Starting the Scorpio Client Software

The Scorpio Server must be in operation prior to starting the Scorpio Client. This allows processing time for the Scorpio Client start sequence and validation of the user ID and password. After Scorpio Server is started, allow ten minutes for full initialization.

The following steps show the desired start-up sequence:

1. Power-up the Scorpio Server

2. Wait 10 minutes for the GPS to acquire and the software to load and initialize.

3. Power-up the Scorpio Client according to instruction 2.4.2.

4. Enter User ID and Password, if asked.

NOTE: The Spectrum monitoring measurement equipment does not have to be turned on in order to start up Scorpio Client. However, the equipment will have to be powered on prior to executing a measurement from a Server. After you verify the operational status of Scorpio Server, you are ready to operate the Spectrum Monitoring system. The first step is to power up Scorpio Client.

2.4.1 To Start the Scorpio Server, Turn on the Spectrum Processor

Turn on Scorpio Server computer.

Allow 10 minutes for software boot and GPS lock.

2.4.2 To Start the Scorpio Client

1. Turn on Scorpio Client computer. A login dialog box may open when Windows appears.


2-3

2. Type your user ID on the login screen, if asked.

3. Type your password on the login sheet. Your password can contain up to 14 characters and is case sensitive, if asked.

4. From the Task Bar, select Start Programs Tcibr Scorpio Client or double click the short cut icon, if provided.

5. A "Select Language" dialog box may appear. Select language of choice.

The Scorpio Client opening screen appears (Figure 2-1).

2.8 Exiting the Scorpio Client Software and Shutting Down the System

To power down Scorpio Client, you must first exit the Spectrum Monitoring system and then Windows. Choose File Exit from the main menu to exit the Scorpio Client. A dialog box will then appear with the message "Do you really want to quit the Scorpio Client Application?" Click [Yes] to exit.

CAUTION: If you forget to follow the above steps, it is possible to lose some of the data you have just entered.

Click on the <Start> button then Select Shut Down. You are then presented with the Dialog box

selection to "Shut Down Computer." Click Shut Down Computer and click on Yes. The system performs an orderly shutdown and you may turn off Scorpio Client computer.

NOTE: Be sure to leave the Spectrum Monitoring system measurement Server equipment powered on. Scheduled measurements cannot be run unless the equipment is accessible to Scorpio Server.

2.9 Backing Up and Restoring Files

Spectrum Monitoring databases should be backed up regularly according to a preset schedule. Use the Microsoft Windows Backup program that is accessed from Start Programs Administrative Tools (or equivalent) menu. All files from the following files should be backed up every day:

• Scorpio Client Computer – c:\Program Files\TCIBR\Scorpio Client\Database

• 8067A Computer – c:\Program Files\TCIBR\Scorpio Server\Measurement Database

• Server Model other than the 8067A – c:\Documents and Settings\All Users\Application Data\TCI\Scorpio\Measurement Database. You may first have to show hidden files and folders.

2.9.1 Using Backup/Restore You can use Backup to back up files on your hard disk. You can back up files to floppy disks, a tape

drive, or another computer on your network. If your original files are damaged or lost, you can restore them from the backup. To start the Backup/Restore process:

• You can also start Backup by clicking, Start Programs, Accessories, System Tools (or equivalent) and then clicking Backup.

• For information about how to use Backup, click the Windows Help menu in Backup.

In the event that a file becomes corrupted, follow the Microsoft Windows Restore process to replace the corrupted file with a previously backed up version of the file.

2.10 The Scorpio Client Task Management System

The task management system operates on the principle that the system communications are not reliable. This assumption allows the system to function in a very robust fashion even when the network is working at a marginal level. Tasks are posted to a scheduler that is responsible for the execution of the specific task. This scheduler executes the measurement request as specified by the operator and upon


2-12

completion stores the data until it is requested by Scorpio Client application. Scorpio Client application can then request the data from the task management system at any time after the completion of the measurement.

3. SPECTRUM MONITORING TASKS Part of using the Spectrum Monitoring system is understanding the capabilities of the system. This

chapter introduces you to some of the features you can use to effectively monitor the radio frequency spectrum. You’ll also learn how to perform the basic functions of the system, such as adding and/or modifying Spectrum Monitoring Task. The application includes a Taskbar for function selection. These buttons can be used for quick access to common system functions. Functions are grouped logically with helpful icons to aid the operator in the proper selection.

Before any Task can be performed, Client must connect to a measurement Server using Network Setup under the Taskbar Tools item.

3.1 Metrics - Task Calendar (Optional)

A Spectrum Monitoring Task is typically initiated in response to a need. The Task is created in a calendar called a Task Calendar. This entry contains information related to the particular Task assignment and consists of instructions, notes, measurement setups, and results. The Scorpio Client performs two types of measurements: interactive and scheduled. Each type of measurement provides unique advantages.

Interactive measurements provide access to equipment available in the system for specific monitoring applications so that you can:

• Perform real-time signal analysis

• Pre-scan the frequency spectrum

• Listen to Signal interference

Scheduled measurements give you the ability to operate the Spectrum Monitoring system unattended. This feature allows the user to:

• Capture and document important signal information

• Not miss important spectral events

• Coordinate monitoring around the clock

• Monitor the spectrum 24 hours a day

• Take measurements via automated computer

• Free the operator to follow up on measurement results

In addition, multiple types of measurements can be performed in sequence on different bands and at different times.

• Frequency Measurements

• Modulation Measurements

• Field Strength Measurements


3-2

• Bandwidth Measurements

• Spectrum Occupancy Measurements

• Direction Finding Measurements

3.1.1 Entering Task Items Task items include measurement setups, and measurement results. When you enter a Task, you

always have the opportunity to give it an identifying name. Once entered, each item is placed into the Task Calendar and is viewed from the main Task Calendar screen.

Figure 3-1 Task Calendar Window

Table 3-1 Task Calendar Window Field/Button Item Descriptions

Field/Button Item Description Hour Increment Bar (12a to 12a)

This display bar shows Tasks that have been scheduled into a particular time slot. This is to display all Tasks the have been scheduled to run within the entire 24 hour period of the day. The marker color relates to the status of the Task performed.

HINT: Click on the Hour Increment Bar to scroll the 5-Minute Increments task list.

5 Minute Increment Task list with Scroll Bar

This display region shows a limited amount of 5-minute intervals for scheduled measurements being performed. The user may scroll up or down to display any 5-minute period of the day. Desired measurement Tasks are listed with the identification assigned to them and a colored box that displays the Tasks status.


3-3

Any stored Tasks can be reopened and modified. The Spectrum Monitoring system provides a quick way to delete, modify, or find a Task.

NOTE: Scheduled DF Measurements (calendared events) will only be displayed for the currently connected Server. Only one Server will be connected at any one time for Scheduled events.

Entries are made to the calendar by selecting the desired day/time and entering specific measurement requirements into the customization tabs and then clicking on <Schedule>, located on the "Measurement" tab. The item entry tabs are discussed below in Table 3-2 through Table 3-9. Placing a check mark into the box displaying the type of customization desired gives the user access to the additional customization tabs.

In addition to listing the scheduled Task items, the Task software indicates the item status as follows:

Table 3-2 Scorpio Client Calendar Box Color Descriptions

Task Calendar Box Color Description

Blue “Task” is currently being sent to the Spectrum Processor.

Red “Task” Request has not been sent to; or “Task” Result confirmation has not been received from the Spectrum Processor.

Green “Task” has been received and scheduled for completion by the Spectrum Processor.

Yellow “Task” should have been run but confirmation of Task Results has not yet been received from the Spectrum Processor.

Grey “Task” Results have been successfully retrieved from the Spectrum Processor and are available for examination.

Red check Mark “Task” is currently selected for viewing or editing.

Optionally, the Task Calendar is capable of identifying and displaying externally generated

measurement results. As an example consider SHF measurements generated from an external Spectrum Analyzer, where the measurements are stored in files. These files can be loaded and viewed in an external measurement viewer.

An externally generated measurement result is given the label "EXT" to identify it as an external measurement. Each external measurement is numbered 1, 2, 3… in the Task Calendar, indicated with "-n" that appears to the right of the "EXT." The filename used by the operator when saving this file appears in parenthesis to the right of the number identifier. For example, two external measurements may be labeled "EXT-1 (filename1.bmp)" and "EXT-2 (filename2.gif)."

External measurement files placed in a subdirectory "External" will be located by the Scorpio software and will appear in the Task Calendar window based on the date/time of the saved file.

Selecting an external measurement result in the Task Calendar by double clicking it will open the result for review/printing. There is a setting in the ScorpioClient.ini file so that it is possible to determine what application (Notepad, Paint, etc.) will launch to open the result files.

3.1.1.1 Measurement Central to each scheduled Task, are the measurements you perform to gather required information.

When you enter a scheduled Task, you must specify the following basic characteristics:

• Center frequency

• Bandwidth

• An identifying name

One or more of the following characteristics must be selected for measurement:

• Occupied bandwidth

• Modulation

• Field strength

• Frequency

• Direction

Figure 3-2 Scorpio Client Task Calendar Measurement Tab

Table 3-3 Scorpio Client Task Calendar Measurement Tab Field/Button Item Descriptions

Field/Button Item Description

Frequency Allows the user to enter the center frequency you want to measure in this field.

Bandwidth Allows the user to enter the necessary bandwidth for the modulation mode of the signal you want to measure in the Bandwidth field.

NOTE: Bandwidth values inconsistent with selected de-modulation mode will yield inaccurate results.

Identity Allows the user to enter a value for identifying the signal to be measured.

Antenna Allows the user to specify which antenna, from a list of available antennas, to be used for the metrics measurements. Note that the reference antenna is always used for the Direction measurements, regardless of antenna selection.

Table 3-3 Scorpio Client Task Calendar Measurement Tab Field/Button Item Descriptions


Station Name When in "On-line" mode, this shows the currently connected Measurement Server and cannot be changed. When in "Off-line" mode, all defined Measurement Servers are listed and can be selected. Any previously retrieved measurements can be reviewed.

Schedule (D) – Delayed

(I) – Immediate

The <Schedule> button allows you initiate the Task measurement to be scheduled and will contain all parameters that have been specified with the use of the additional tabs.

Clear Clears the entries in all tabs of the currently selected Task.

Remove Removes the currently selected Task from the schedule. If you inadvertently create an unnecessary Task, or if you no longer need the Task, you can easily delete it from the mission list.

Check Boxes: Bandwidth Modulation Field Strength Frequency Direction

These are toggle switches that allow the user to gain access or remove access to the additional entry tabs that are available. Placing a check mark into the box by clicking on it gives the user access to that entry tab.

3.1.1.2 Bandwidth The "Bandwidth" measurement reported by the signal measurement helps you identify over-

modulated signals and also helps you identify the type of signal you are monitoring. The measurement works for all signal types including AM, FM, SSB.

Bandwidth measures the occupied bandwidth of the signal. You can select the one of the following bandwidth analysis methods:

• Beta %dB - measures the occupied bandwidth using the β 99% method

• xdB - measures the occupied bandwidth using the x-dB method

• Averaging Method - provides options by which to average the measurement data

• Measurement Time – provided optional Dwell and Repeat times.

Figure 3-3 Scorpio Client Task Calendar Bandwidth Tab


3-6

Table 3-4 Scorpio Client Task Calendar Bandwidth Tab Field/Button Item Descriptions


Beta %dB Setup Checkbox Y (dB) Beta (%)

This method finds the bandwidth within which β% of the energy is contained. A typical value for β is 99% for this measurement Server to collect a block of data and calculate the power spectrum using FFT. It repeats the collection and FFT process using specified averaging method processing for a specified dwell time. Next it estimates the noise floor and zeros out all FFT bins that are less than Y dB above the noise. A typical value for Y is 6 dB.

xdB Setup Checkbox X1 (dB) X2 (dB)

This method finds the frequency limits such that all spectrum components outside these limits are at least x dB below a 0-dB reference level. Since the occupied bandwidth is the value that is regulated (No. 147 of Radio Regulations), this method is not the preferred one. In order to obtain better agreement with the occupied bandwidth measurement, the values of x vary with modulation type and have been empirically determined.

Averaging Method: Mean RMS Max Hold

Select on of the averaging methods to average the results from each measurement repetition. Selection of the Averaging Method in the Bandwidth Tab is independent of other choices of Averaging Method. For example: The user may set a “Mean” Averaging Method in Bandwidth, and an “RMS” Averaging Method in the Modulation Tab.

Measurement Time: Dwell (ms) Repeat

Dwell sets the measurement duration in milliseconds. Repeat allows the user to specify how many times to repeat the measurement.

3.1.1.3 Modulation

The "Modulation" tab allows the user to set modulation characteristics of the signal in the selected modulation modes. The system is capable of measuring "Amplitude," "Frequency," and "Phase modulation."

Figure 3-4 Scorpio Client Task Calendar Modulation Tab


3-7

Table 3-5 Scorpio Client Task Calendar Modulation Tab Field/Button Item Descriptions


Measurement Selection: Amplitude Frequency Phase

For AM signals, the modulation depth m is measured. This is defined as: m = (Emax – Emin)/(2Ec) where Emax and Emin are the maximum and minimum amplitudes of the modulated signal and Ec is average amplitude of the signal.

For FM signals, the primary measurement is the frequency deviation.

For PM signals, the primary measurement is the phase deviation. This is measured similarly to the FM measurements.


Select one of the averaging methods to average the results from each measurement repetition. Selection of the Averaging Method in the Modulation Tab is independent of other choices of Averaging Method. For example: The user may set a “Mean” Averaging Method in Bandwidth, and an “RMS” Averaging Method in the Modulation Tab.

Measurement Time: Dwell Repeat

‘Dwell’ sets the measurement duration in milliseconds. “Repeat” allows the user to specify how many times to repeat the measurement.

3.1.1.4 Field Strength "Field Strength" tab allows the user to measure the field strength of the signal. Field strength

measurements provide detailed information to determine the adequacy of radio signal strength and the effectiveness of the transmission source. It measures field strength at a specific frequency. Each time the operation is executed, the Spectrum Monitoring system will measure the field strength of a specified signal. This is primarily utilized in mobile measurement applications. You can use field strength measurement to:

• Determine the adequacy of a radio signal strength and the effectiveness of the source transmitter

• Ensure compliance with the relevant radio regulations

• Measure spatial-distribution of field strength

• Measure variation of field strength due to shadowing and other loss mechanisms

• Determine the interference effects of a given intentional radio emission (electromagnetic compatibility)

• Measure propagation phenomena

“Dwell” sets the measurement duration in milliseconds. “Repeat” allows the user to specify how many times to repeat the measurement.


3-9

3.1.1.6 Direction The "Direction" tab allows the user to specify or alter existing DF entries. When performing DF, the

user may specify a confidence value for the signal of interest being tasked. This window also allows the user to specify a bandwidth to be used if it varies from that used in the "Measurement" tab.

Figure 3-7 Scorpio Client Task Calendar Direction Tab

Table 3-8 Scorpio Client Task Calendar Direction Tab Field/Button Item Descriptions


Confidence The Confidence factor (CF) allows the user to set a confidence value in percent. Confidence ranges from 1 to 99, with 99 being high confidence. A typical value for confidence is 80*.

Bandwidth Bandwidth allows the user to enter the necessary bandwidth for the modulation mode of the signal you want to measure in the Bandwidth field.

Polarization (optional) Polarization allows the user to perform the measurement(s) using the vertical or horizontal components of the antenna, if available.

Use this Bandwidth (not Measurement BW)

Check this box to specify whether to use the Bandwidth entered into the Measurement Tab or the Bandwidth entered above.

Measurement Duration Dwell Cuts

Dwell sets the measurement duration in milliseconds. Cuts allow the user to specify how many times to repeat the measurement.

NOTE: Server software will finish the DF measurement when either of those two parameters reaches specified value.

*Note: The confidence number returned from the measurement is based on how well the amplitude and

phase from each antenna matches the computed answer. A perfect agreement will return a confidence of 99. Due to multipath propagation, it is difficult to always have perfect agreement. A confidence of 80 will provide a useable DF.

3.1.1.7 Tasking Options The "Tasking Options" tab allows the user to attach additional scheduling requirements to a Task.

The user can schedule the Task to be run immediately or can delay it running for any time later. Tasks can also be scheduled to be run only at the time specified (assuming the equipment you’ve selected is available) or when convenient. The Scheduling tab also allows you to schedule how often and how many times you want the measurement to be executed.

If you select Delayed:�You can specify the Task to be run when it is convenient for the Scorpio Server to run it. If a measurement must be made at a certain time, then the Rigid button should be chosen to confirm that the measurement time should not be varied upon. The user can also specify whether or not this measurement should be repeated.

Repeat Options Task Count Period

If the user has chosen that this Task be repeated, a Task count must be specified. Period defines the interval between repetitions.

3.2 Metrics - Task Results (Optional)

After a measurement is complete, the results for the measurement can be viewed and evaluated to determine what actions may need to be taken, if any. The decisions you make regarding the appropriate action depend on the policies of your organization and management. No recommendations are made here.

When the signal measurement is complete, you can view, print or save a report that summarizes the data that was collected. Click on the desired Task in the Task Calendar to select it. Then click the Task Results button in the Metrics tool bar to display the results.

Measurement results can be viewed in reports that can be viewed, printed, and imported into Microsoft Word for windows. In addition to all information relative to a measurement setup and a summary of its results, reports include the following information:

4. SPECTRUM MONITORING DEVICE CONTROL

4.1 Device Control – Homing DF (Optional)

The "Homing DF" feature gives the operator the ability to quickly and easily locate the source of an emitter using a mobile monitoring station(s). It provides a direction indicator to the emitter relative to that of the vehicle. The "Homing Mode" results are displayed on the integrated map display.

The "Homing DF" feature covers the entire valid frequency range. DF measurements determine the direction of arrival or azimuth of a signal of interest with regard to both relative to the vehicle and True North direction. This directional information is also referred to as the line of bearing (LOB) data.

A DF measurement gathers LOB data from the mobile station Tasked with a DF request. The DF results are displayed as LOBs on a map. The LOBs are drawn as a line segment from the location of the vehicle (when the DF measurement was taken) to the edge of the map, in the direction of the returned azimuth. The software processes the LOB data obtained from each DF measurement location and calculates the position or "FIX" on the transmitted signal. The Global Positioning System (GPS) is utilized to record DF station location in reference to the Signal of Interest being Tasked.

Digital Signal Processing (DSP) techniques are used to determine the azimuth angle of arrival of any signal of interest (azimuth angle is measured from magnetic north). The DF measurement method used in the Spectrum Monitoring system is an implementation of the Correlative Interferometry technique as described in the ITU Spectrum Monitoring Handbook.

NOTE: A DF result consists of a bearing and the GPS location of the measurement server. If for some reason the GPS unit is offline, Scorpio Server will return the value stored in its “equipcontrol.ini” file. The default value is set to training server location. This value is found in the “gps” section of the file under the “location =” key.

NOTE: Double-clicking at the edges of the Relative Bearing chart causes the chart to “pop-up.” This element when “popped-up” is detached from its parent screen and displayed in a separate window which can be repositioned and resized


4-2

Figure 4-1 Scorpio Client Homing DF

You can use DF to:

• Locate unauthorized transmitters

• Locate transmitters in distress situations

• Locate interfering transmitters which cannot be identified by other means

• Locate sources of harmful interference of reception, such as electrical equipment, defective insulators on a power line, and other interference

• Identify transmitters, both known and unknown


4-3

When the "Homing DF" dialog is active, an immediate DF measurement is requested at regular intervals. The interval used is the number of seconds as shown in the "Repeat Rate" pull-down list. As each DF Result is received, the LOB, from the location of the mobile DF station to the emitter is displayed on the Relative Bearing Chart. The LOB is displayed as a needle pointing towards the emitter, relative to the direction the mobile DF station was facing at the time of the measurement. If the needle is pointing "Right," then the emitter is somewhere to the right of you. If the needle is pointing "Forward," the emitter is somewhere in front of you, and so on. Only the five most recent LOBs are displayed on the chart. The most recent LOB received is displayed in yellow and the previous four are displayed in Grey.

When a DF measurement is requested, certain information is sent along with the request, including the frequency, bandwidth, confidence factor, and priority of the request. The frequency and bandwidth values are taken from the "Frequency" and "IF Bandwidth" options on the "Monitor Receiver’s" dialog box. The confidence factor is selected by the operator using the associated "Confidence Factor (CF)" spinner control. The priority is higher than that of other measurements (as from the Task Calendar window) and is selected internally by the system. Only those LOBs that have a measured confidence factor and SNR that meet the operator entered confidence and SNR values are displayed.

The most recent LOB is always displayed on the "Relative Bearing Chart," but not always on the Map. There are three rules by which a LOB is displayed on the Map: It is the first LOB returned, it is selected for display when the operator presses the <DF Update> button, or it is selected from the "Homing FIX" dialog. By pressing the <DF Update> button, the most recently returned bearing is included in the current Homing DF “Mission.” All included bearings are maintained, and may be used in a FIX calculation. Not including bearings is useful in a mobile system when trying to locate a fixed emitter.

The Map displays vehicle positions as a red square, and bearings as colored lines. All of the displayed bearings are automatically used to perform FIX calculation and any wild bearings rejected by the FIX will be colored yellow, while accepted bearings will be colored red.

The Homing DF dialog works in conjunction with the Homing FIX dialog. All included bearings are given to the Homing FIX dialog. When a specified number of bearings are included (selected in the “Auto-FIX Rate” pull-down list), a FIX is automatically calculated based on the most recent, specified bearings. These bearings can be seen and either selected/deselected in the FIX window.

Table 4-1 Scorpio Client Homing DF/Map Display Field/Button Item Descriptions


Relative Bearing Chart This directional “indicator” displays the source of the emitter relative to the direction of the mobile station. For instance, if the mobile station turns directly into the signal, the Relative Bearing Chart will display a pointer emitting from 360 degrees whereas if the signal is coming directly from the right side of the front of the mobile unit, the display pointer will indicate 90 degrees.

Fix Results Lat, Lon UTM

Displays the Latitude and Longitude in degrees:minutes:seconds or Universal Transverse Mercator (UTM) results of the last FIX obtained.

Network Audio (optional) When selected, audio is routed from the measurement server to the client.

DF Measurement Parameters Freq Bw CF, SNR (optional) Polarization (optional)

Displays the currently set frequency and bandwidth parameters as set on the Monitor Receiver. The CF allows the user to set a minimum confidence value. The SNR allows the user to set a minimum Signal-to-Noise ratio value.

Polarization allows the user to perform the measurement(s) using the vertical or horizontal components of the antenna, if available.

Auto-FIX Rate This item sets the number of bearing reports to be used when calculating a FIX.

Repeat Rate This item sets the number of seconds that elapse between DF requests.

DF Update This button takes the Bearing results just received and places them into the FIX screen for use in calculating a FIX.

Automatic Updates When selected, all Bearing results received are placed into the FIX screen for use in calculating a FIX (this provides an automatic way to perform a “DF Update”).

DF Request Sends an immediate request for DF measurement to the Spectrum Processor.

Export to File, <…> (optional)

When selected, both the DF measurement request and Bearing result is appended to an external file. This file is a comma-delimited text file. Each DF request and result is displayed on a separate line.

Pressing the <…> button allows the user to select both the name and location of the external file to be used.

4.2 Device Control – Homing FIX (Optional)

After desired line of bearing data has been obtained, the user may request a FIX for a target. Figure 4-2 is the FIX calculation screen. The operator selects the line of bearing data that will be used for the calculation by selecting each one and clicking the <Calculate Fix> button.

Bearing Selection [ Azimuth in degrees (Signal Strength in dBm) ]

These buttons allow the user to select which Bearings to use to calculate a FIX. Bearing selections are added as DF requests are returned from the Spectrum Processor.

4.3 Device Control – Monitor Receiver (Optional)

Most traditional receivers have separate Pan IF displays for displaying just a portion of the RF spectrum. TCI’s solution provides this functionality as a "Receiver Virtual Control Panel" on the computer monitor. This Virtual Control Panel (VCP) has familiar controls associated with typical stand-alone receivers, providing interactive control of the receiver unit. The screen includes controls for frequency, modulation, and amplitude control. Receiver status information will be displayed on the same screen. The receiver audio may be routed through the audio distribution system. Figure 4-3 shows an example of the receiver "VCP."

The "Monitor Receiver" dialog box allows you to set up a specific receiver to perform signal measurements. The virtual receiver display allows you to view the signal being monitored in a real-time frequency domain. Multiple receiver controls provide the capability to analyze and capture signal characteristics.

Antenna (optional) Allows the user to specify which antenna, from a list of available antennas, to be used for monitoring.

Network Audio (optional)

When selected, audio is routed from the measurement server to the client.

Squelch (optional) When selected, audio from the measurement server is squelched (muted) when the RF Level falls below the selected squelch level.

Peak Hold

Average %

When selected, the Pan trace is generated using only the maximum levels.

When selected, the Pan trace is generated by using a running average, with the most recent Pan trace averaged with the average of all previously received Pan traces. The most recent Pan trace is weighted according the selected Average % (e.g., if selected an Average % of 70%, the most recent Pan trace is weighted as 30%).

4.3.1 Antenna Selection Control (Optional) Both Scorpio client and server are modified to support multiple choices of the monitoring antenna

(Ref which is the standard antenna or Aux N which are customer supplied auxiliary antenna(s)). The server software maintains the antenna selection. The client receives the current antenna selection from the connected server. The client can also change the antenna selection, but only after it has received currently selected antenna values from the server.

4.3.2 Audio Switching (Optional) The Communications network allows for data and audio communications between all stations. In

normal operation, each subsystem will operate independently, although it is possible to communicate between subsystems. The network communications has to be UP for audio routing between stations to be operational.

Using dialup phone lines, any site is capable of monitoring and/or storing audio from another site. These functions are provided using an audio switch and sound cards. The Spectrum Processor computer has a built-in audio switch and one sound card. The other sound card is located in the local Scorpio Client workstation.

Another major function of the system is the capability to transfer and play digitized audio files (.wav) between all stations.

Audio distribution at the Control Centers is achieved using a standalone software package to control all aspects of audio distribution and digitized audio storage/playback.

4.3.2.1 Telephone Interface In order to receive audio inputs from remote stations, an operator must initiate a phone call to the

desired station. When the call is detected at the remote station, the remote station will automatically answer the phone and connect audio to the line. The Telephone Interface Unit allows the operator to select a phone line and manually dial into a remote station to establish the audio link.

4.3.2.2 Remote Monitoring and Digital Recording (Optional) An operator remotely opens an 8067 receiver at a fixed or mobile station, and tunes the receiver to the

desired frequency. Using the panoramic display, verify the desired signal is currently on air. The operator dials into the remote station to establish the receiver audio connection. Using the

NiceCall software application, route the audio to one or both of the headset channels. Adjust the receiver frequency and demodulation parameters as necessary.

If desired, use the NiceCall software application to set up digital recording of the signal. At this point, the operator will enter "chunk" data, to include:

• Audio File Name

• CC and Remote Station Locations

• Frequency

• Date/Time

• Comments

The CC operator can then set up additional channels for monitoring/recording if desired using the above steps.

If the files are to be transferred over the data network to other fixed or mobile stations, they must be saved as ".wav" files.

Any station in the network using drive sharing and mapping into the network can access digitized audio files.

4.3.3 Remote Audio Monitoring It is assumed that when an operator wants to use resources at a remote station, he will select the

desired station from the station list, and will then have full control of that station. For any site to access audio at a remote site, select the "Remote Monitoring from CC" option.

1. The operator selects desired station, and uses Monitor Receiver dialog to tune to desired frequency. He then verifies the signal is present on the "Tuning Aid" screen.

2. The operator uses the "Audio Switch Setting" dialog to instruct the remote Spectrum Processor audio phone port to automatically answer phone when ring is detected. At this time, the remote audio switch will be commanded to route receiver audio to the phone port.

3. The operator initiates a phone call to Fixed or Mobile 8067 audio phone port. The Spectrum Processor will automatically answer the phone, and the operator can listen to the audio over the phone line.


4-13

4. When the operator is finished monitoring the remote station audio, clicking on <Hangup> will disconnect (takes on-hook) the 8067 phone port, thereby disconnecting the phone.

4.3.4 Audio Recording (Optional) The following steps are used at the Fixed and Mobile stations to record/playback receiver audio at

Scorpio Client workstation.

1. The operator uses the "Monitor Receiver – Connected" dialog to tune the receiver to the desired frequency.

2. To initiate recording, the operator can select the <Recorder…> button to automatically route the receiver audio to Scorpio Client sound card and to start digital recording.

3. This will bring up the "Digital Audi Recorder" dialog.

4. Audio can also be played back through this Dialog.

1. Using the NiceCall software application, select the desired audio file for playback.

2. Route audio to the desired output (headset, tape recorder, or other output port).

3. Use Nicecall software to start, stop, etc.

4. If cassette dubbing is desired, route audio output to the tape recorder, and set the tape recorder up accordingly.

The operator can also transfer the audio output to a remote site using the telephone interface in the output port. Use the NiceCall software to initiate the phone call to the remote site. When the connection is established, the played back audio will be transferred over the phone line.

4.3.6 Audio Source Selection and Volume Control The sound card mixer is used to provide the audio source selection. The operator selects a mixture of

live receiver audio, wave file audio and system alerts. The volume and balance for each source may be controlled as required. Any source may be quickly muted using the "mute" check box provided. The record input level is controlled from this panel as well. The operator selects the input level using the microphone volume control selection.

4.4 Device Control – Pan Display (Optional)

The Panoramic or PAN display is an X-Y plot of signal amplitude versus frequency. This type of display is very useful in viewing signal relationships in the radio spectrum, and is generally referred to as a tuning aid. The PAN display includes bandwidth selection, frequency separation measurement, peak hold, and maximum signal functions. Each of these functions is discussed in the following paragraphs. The PAN display is created using the unfiltered IF data and therefore provides a complete picture of the contents of the receiver passband regardless of the selected IF bandwidth the user has selected for listening. This feature allows the user to see all of the signals in the passband even if a 300 kHz bandwidth is currently active.

NOTE: Double-clicking inside the Pan/Waterfall/Spectrogram charts causes the chart to “pop-up.” These elements when “popped-up” are detached from its parent screen and displayed in a separate window which can be repositioned and resized

NOTE: These values can be changed by editing the settings in the Initialization file (ScorpioClient.ini)

The control is set to “Fast” by default the first time dialog box is displayed after launching the program.

4.5.3 Polar Histogram The "Polar Histogram" group is used to display the DF cuts collected in a polar chart. The cuts

histogram is built from the center towards the edge.


4-24

Clusters of cuts can be selected by using the cursor. A one click on the left mouse button will activate an azimuth line. When a desired cluster is identified the mouse button is released and a wedge is then automatically created encompassing the cluster. The size of the wedge can be modified in "Scorpio client.ini" file. The azimuth field is then recalculated from the cuts in the new cluster. This allows the operator to identify the azimuth for non-main clusters.

All DF cuts satisfying the "CF" criteria (as specified in the DF Setup group) are displayed in the Polar-Histogram. The cuts are placed into 1° (one-degree) bins (from 0-359 degrees). The longer the line drawn in any bin, the more DF cuts were collected at that bin’s azimuth. The main cluster of cuts is used for the average azimuth calculation.

Table 4-12 Scorpio Client Polar Histogram Field Item Description

Field/Button Item Description Az This field is automatically filled in by the program. It indicates the azimuth that

has been calculated from the cuts in a selected cluster shown on the chart. It is important to note that the cluster may not encompass all the cuts shown in the chart. Whenever the cuts displayed in the chart are edited using the wedge function the "Az" field gets updated to reflect the actual cuts used in the process. Initially the azimuth field is the same value as that shown in the ‘DF Results’ group "Azimuth" field in the highlighted row.

Sig.Str (dBm) This field is automatically filled in by the program. It indicates the signal strength that has been calculated from the cuts in a selected cluster shown on the chart.

4.10 Device Control – Map Management

The mapping system is based on ESRI® MapObjects® that support map display and controls. The map window is available for the display of DF LOB data, emitter locations, and error ellipses.

Mobile emitters and Mobile stations are also displayed on the map.

4.10.1 Display and Control The map window is accessed with "Homing DF," "Netted DF," “Pushbutton DF/Metrics”, “AVD”

and the “Station Select” functions. The user may select zoom in, zoom out, pan, center, or measurement functions. The coordinate display window changes according to the user selection in the Tools menu. When a tool is selected, the mouse cursor that is displayed over the map windows is changed to reflect the function in use. For example, when the zoom in function is selected, the cursor changes to a magnifying glass with a plus sign in the lens.

Figure 4-18 Scorpio Client Map Display Screen

When no tools are selected the coordinate display window shows the current mouse position on the map in either Lat/Lon or UTM. Marking the UTM checkbox on the main window makes this selection. If the UTM checkbox is not selected, the coordinate display defaults to Lat/Lon in Degree, Minute, Second, and Hemisphere format (Example: 25 00 04N 121 43 08E). The UTM location display selected by TCI is the 14 character international standard and provides location accuracy that is appropriate based on the map scales intended for the system.

4.10.2 Map Measurement Functions Azimuth Measurement Function is used to measure the great circle bearing between two points on the

map using the mouse cursor.


4-40

Distance Measurement Function is handled in three units: miles, meters, and kilometers. The starting point for the distance measurement is selected using the mouse cursor. The user points the cursor over the starting point and clicks the mouse button to anchor the starting point. The user then continues to select points by moving the mouse and clicking the mouse button. The final point is selected by double clicking the mouse button.

4.10.3 Printing The Map The current map may be printed at any time by pressing the print map button. The map is printed to

the default printer specified for the system. The map overlay is always printed on a separate sheet that may be included in hard copy reports generated by the workstation application software.

Inclusion of the map overlay into soft copy reports is handled by saving the map overlay as a bitmap (windows .bmp file) that is inserted directly into a Microsoft Word document. It is also possible to perform a screen capture to insert the overlay into a document.

NOTE: To identify a station on the map, double click on its name. The map display will center on that station’s geographical location.

5.2 Tools – Spectrum Occupancy (Optional)

The Spectrum Occupancy tool furnishes you with easy-to-understand reports of spectrum usage over time. Reporting periods range from several minutes to several weeks. Thanks to the system’s multitasking capability, you may continue using the system to perform other tasks while it is collecting occupancy data.

Spectrum occupancy gathers information on long-time usage of the frequency spectrum and helps you identify frequencies that are free from interference. It measures field strength in a frequency spectrum over a period of time you define. The occupancy results show frequency band usage.

You can use the Spectrum Occupancy measurement to assist in tracking interference or improper spectrum usage. It will also aid you in making observations for use in frequency management such as spectrum planning and allocation and channel usage reports.

To get an occupancy report you need to specify the following parameters:

• One or more frequency bands to monitor

• The channel widths within each band

• The period of time over which to collect data

• Signal collection threshold level

• One or more graphs to portray the occupancy results


5-3

Taken together, these parameters constitute an Occupancy Task. The system is capable of running and storing results for five Occupancy Tasks simultaneously. An occupancy task can store no more than 20,000* (or 100,000, see note below) data points. Attempting to store more will invoke an error message. This limit can be approached in two ways, depending on whether time-of-day is selected:

N_channels ≤ 20,000* (time-of-day is NOT selected) or,

N_channels * N_tod ≤ 20,000* (time-of day IS selected)

where

n = total number of bands in the task and

)(_)(__

sIntervalStoragesDurationFixedtodN =

If your task is rejected for having too many data points, you must reduce the number of channels,

shorten the measurement duration, and/or increase the storage interval. The graphical output choices are described in Table 5-2. Graphs can be viewed on Scorpio Client screen as well as printed to paper or saved to disk.

NOTE: Spectrum Occupancy tasks need to be suspended in order to hear any audio output.

NOTE: *If your system does not include any 8067A Spectrum Processors, a task can store up to 100,000 data points.

Schedule Immediate Delayed

Use this input area to select the type of scheduling for this Task. • If you select this radio button, the system will schedule your task to

begin as soon as you click the <Run> button. This is the default selection.

• Select this radio button to be able to enter a specific date and time for the task to begin. The system will schedule the task when you click the <Run> button. The task will begin at the date and time you specified in the Date and Time fields.

Storage Interval Use this input to specify the storage interval. Storage interval is the time between updates of the database. It defines the time-axis resolution of Occupancy versus Time of Day graphs, and defines how often task completion estimates are re-computed. The initial value is 15 seconds.

Msg. Length min gap Use this input to specify the message length minimum gap. The system considers any interruption in transmission of this value or greater to be the end of one message and the start of another. The initial value is 15 seconds.

Antenna Allows the user to specify which antenna, from a list of available antennas, to be used for the Spectrum Occupancy measurements.

Station Name This drop-list shows the different stations available. On initial display of the Spectrum Occupancy dialog, this control is used to display the station currently connected to. If this list is blank, there is no connection to any station. When in "off-line" mode, this drop-list is also used to view tasks and parameters of tasks that were scheduled from other stations. Scorpio Client will not switch the connection to another station when the selection is changed, therefore, requests to run tasks will be ignored or disallowed.

All Single Channels Mark this checkbox to simplify the entry of single-frequency bands. When this box is checked the band list accepts start frequencies only. If your list includes stop frequencies and you mark this checkbox, the system will delete them with your permission.

Threshold Fixed (dBμV/m) Noise Riding (dB)

Use this input area to specify a signal threshold level for occupancy measurements. Only signals that exceed this threshold are considered when compiling occupancy statistics. • Select this radio button to enter an absolute signal threshold level.

This is the default selection. The initial value is 10 dBμV/m. • Select this radio button to enter a relative threshold, expressed as

dB above noise level. The system dynamically adjusts the threshold, maintaining it above the noise level by the amount you specify.

Duration Fixed Confidence Based

Conf Level (%)

Accuracy (%)

Use this input area to set the length of time your occupancy task will run. • Select this radio button to enter a fixed measurement duration. This

is the default selection. The initial value is 5 minutes. • If you select this radio button, your task will run as long as it takes

to achieve the confidence level and accuracy you specify. The system estimates the completion time and posts it on the Occupancy Results screen. This estimate is updated at every storage interval. In general, higher confidence levels and tighter accuracy result in longer runs. Channels with low occupancy also increase the run time. The task finishes when 80% of the channels meet the confidence and accuracy requirements. For more information on sampling principles, please refer to paragraph 3.3.3.4.4 of the ITU Spectrum Monitoring Handbook (1995).

On initial display of the DF Scan Results dialog, this control is set to the station currently connected to, or left blank if there is no connection to any station. When in "off-line" mode, this drop-list can also be used to see the tasks on other stations. Scorpio Client program will not switch connection to another station when selection is changed, therefore any request to terminate, suspend, or resume tasks will not be allowed. Audio will only be heard when the currently displayed window is the Monitor Receiver, Pan Display, Pushbutton DF/Metrics or Homing DF. Pausing all tasks but keeping the DF Scan Results window active will not enable Audio.

NOTE: If a task is suspended by clicking the <Pause> button, the estimated stop time for the task will not be updated and will remain the same. When the current system time reaches the task’s stop time, the task will not continue running no matter what state it is currently in. (E.g. if task is suspended when stop time is reached, the task will not continue when <Resume> button is clicked. Task status will be completed.

DF Scan Tasks A scheduled or running task will initially be displayed with stop time and date being blank. This indicates that results are not yet available, and the Get Results button will remain disabled at these times.

Status will be updated regularly every storage interval time specified for the task. If Station Name is switched to a non-connected station, any running, suspended, or scheduled task at the station will be displayed to have a status of “Unknown.”

Get Results Click the <Get Results> button to retrieve results for the highlighted task. The graphical representations you requested for the task will loaded into the Results window. Button will not be enabled until results are available.

Pause/Resume Click the <Pause> button to suspend the highlighted task. You may then get results for the task. Click this button again to resume. When the status of a selected task is “Suspended” button will be labeled “Resume.” Pausing is useful for listening to audio when controlling the Monitor Receiver because background tasks, such as DF Scan, are interleaved with audio data, which creates intermittent audio data.

NOTE: When audio data is still intermittent after all background tasks are suspended, another workstation that has logged into the same server is running background tasks.

Terminate Click the <Terminate> button to end the highlighted task. As a precaution,

the system asks for confirmation before terminating the task. You cannot re-start a terminated task, but you can get any results it may have gathered.

Delete Click the <Delete> button to permanently remove the highlighted task from the table. As a precaution, the system asks for confirmation before deleting the task. A deleted task is permanently removed from the database. This includes its task ID number, its setup parameters, and any results it may have gathered.

Azimuth vs. Frequency This graph shows the results retrieved from the Measurement Server after the Get Results button is clicked on. Each data point is plotted using a color coded cross, and represents DF measurements at a certain Frequency (X-axis) coming from a certain Azimuth (Y-axis)

The colors used in the color coding scheme are as follows:

White Indicates that this data point is among the data points that received the least number of DF Cuts.

Yellow Indicates greater number of DF Cuts than the White cross.

Green Indicates greater number of DF Cuts than the Yellow cross.

Blue Indicates greater number of DF Cuts than the Green cross.

Black Indicates that this data point is among the data points that received the greatest number of DF Cuts.

The higher number of cuts, the better the probability that a signal is being transmitted at the associated LOB.

6.2 Server Workload (Optional)

The Server Workload screen allows the operator to observe the daily workload scheduled for the currently connected server, so that an operator can decide which server would be the best to use for pending tasks. The Server Workload screen shows the current workload for the day the operator selects. Tasks shown will be running, scheduled, or suspended. Completed tasks are not shown.

After the operator selects the desired day for viewing, the <Request Workload> button is pressed. The operator can then view the tasks for that server. The tasks are initially sorted by their starting time, but can be subsequently sorted in ascending or descending order by clicking the right mouse button on any column header. The operator can view where the request originated (the client that scheduled the task), what type of task has been scheduled, the state of the task, and the start and end times for the task, as shown in Figure 6-2. For those tasks initiated by the local client, the Client Name is always "Local," and the data is displayed in blue; otherwise the data is in black.

7.1 Troubleshooting Guide

Table 7-1 Scorpio Client Error Messages Symptom/Solution

Symptom Solution

When trying to schedule a task in the Task Calendar, a message displays “Operation must use an updateable query” or “Query not updateable.”

When starting Scorpio Client, a message displays “Cannot delete data.”

ScorpioClient.MDB is read-only; you must make it writeable (use Explorer or File Manager to remove read-only (R) attribute.

When in Task Calendar, a message displays “Syntax error or access violation.”

ScorpioClient.MDB is read-only; you must make it writeable (use Explorer or File Manager to remove read-only (R) attribute.

Task Calendar cannot schedule a task because the <Schedule> button is disabled.

Not connected to measurement service (Scorpio service)

Selected date/time is in the past

Exceeded 10 tasks in currently selected time slot

BIST - <Request BIST> or <Request Diagnostics> button disabled.

Not connected to measurement service BIST or Diagnostics tests currently in progress

Rejected connect by client clientname

This message indicates that another workstation is currently logged on to the same Server and is currently displaying Pan data (Monitor Receiver, Pan or Pushbutton DF window). Scorpio Server only provides one interactive socket to communicate with Clients. Therefore an interactive socket can only be provided to only one Client at a time. Any request for the interactive socket when it is unavailable will be rejected, and the error message will be displayed across the pan window area. The message will remain until the interactive socket is retrieved.

NOTE: Scorpio Client application will not automatically retry requesting for the interactive socket. It will be the user’s responsibility to keep requesting (by clicking Run button or clicking Dialog’s icon at the taskbar)


7-2


Symptom Solution

No audio is recorded using the Audio Recorder in the Monitor Receiver screen.

Recorded audio includes background noise.

Verify that the “What u Hear” or “Digital Stereo Mix” volume control is selected as the recording device. This is done in the Windows Volume Control Application.

If the “Digital Stereo Mix” volume control is not shown as a recording device, modify the “DigitalStereoMix” key in the Windows registry from the value 00 to 01. Add the (binary) key if it does not exist. This issue is prevalent on DELL laptops with a SigmaTel Audio card. To modify the Windows registry, run the regedit or regedt32 command. The DigitalStereoMix key is found at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\4D36E96C-E325-11CE-BFC1-08002BE10318\0005\Settings\filter\rear. Once the value is set to 01, close the registry editor and reboot the machine. Then verify that the “Digital Stereo Mix” volume control is selected as the recording device.

Waterfall/Spectrogram

Graph Updates very slowly. Decrease “Request Time” value in [Waterfall Display] section for ScorpioClient.ini file.

While in Waterfall/Spectrogram graph mode, the application does not respond to mouse clicks.

Increase “Request Time” value in [Waterfall Display] section for ScorpioClient.ini file.

After connecting to a Server while running Scorpio Client, the computers systems clock time changes to the wrong time.

Scorpio Server’s computer is not set to GMT time. Go to Date/Time application in the Windows Control Panel on the Scorpio Server, and choose (GMT) Greenwich Mean Time: Dublin, Edinburgh, London, Lisbon” time zone. Then clear the “Automatically adjust clock for daylight saving changes” checkbox.

Spectrum Occupancy

When scheduling an occupancy task, the message “The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again” is displayed.

The initialization file, “ScorpioClient.ini,” has read only properties. Find the initialization file (usually in the “c:\winnt” directory), and clear the read only property checkbox.


7-3


Symptom Solution

When scheduling Occupancy Task, the message “Occupancy Task has too many channels. Edit Bandlist to decrease channels” is displayed.

The band/s in the list has exceeded the maximum number of channels allowed. Reduce the number of channels by several ways (each can be used as a solution in itself):

• Edit the band/s to have smaller ranges for start and stop frequencies.

• Change bandwidth to a larger value. • Increase the storage interval time. • Exclude bands.

NOTE: At least one band must be included. Do not request “Time of Day Results.” Clear its checkbox in the Graphical Representations group.

Decrease the fixed duration time.

Start Up

Windows restarts when starting Scorpio Client.

There is no properly programmed dongle key plugged into the parallel or USB port.

The dongle key is damaged (needs to be replaced).

The parallel or USB port is not available.

7.2 BIST Processing Logic

The Scorpio Client contains self-test logic to determine the operational status of the system. This test logic performs tests on all of the system's server hardware components, attempts to discover any hardware fault, and provides maintenance personnel with enough information to determine the location of the fault. The test is initiated by performing a BIST operation at a Scorpio Client workstation that has a network connection to the Scorpio Server to be tested.

To make full use of the BIST fault and status indications, the person that interprets these indicators should possess a basic understanding of the function of each hardware component and the signal paths (RF, IF or baseband, digital, and audio) throughout the system. The Scorpio Client contains various BIST signal sources throughout the system. Knowing where each of these signal sources is located in the system and how it is used during BIST will aid in interpreting the BIST results.

The BIST processing logic is fully automatic without any human interaction to change hardware configuration or witness test results.

Three different processors are used to determine the operating status of different parts of the total system. The CPU (Pentium processor) provides the status indicators for the global positioning system (GPS), fluxgate compass, and a portion of the DSP card. The node B DSP tests the node B DSP portion of the DSP card. The node A DSP performs some additional DSP tests pertaining to node A processing and tests all of the remaining hardware components. These hardware components are: A/D & NBT card, Clock/Ref card, A/D & I/O card, Audio Switch card, RF/IF MUX card, VHF receiver cards, HF DF


7-4

receiver, HF metrics receiver, HF DF switch, VHF DF switch, UHF DF switch, HF antenna, VHF antenna, and UHF antenna.

The sequence of the BIST processing logic is important when interpreting the BIST results. The BIST processing logic in the node A DSP does not stop when a fault has been determined -- it continues through all of the tests. This can result in multiple faults being reported that were all caused by a single failure. Knowing which fault was detected first in the BIST processing logic will isolate the hardware component (or possible components), which is faulty. The test sequence starts at the CPU and tests hardware components in the reverse order of the normal signal flow -- processors, digitizers, receivers, antenna switches, and antennas. The exact sequence of hardware components tested during the BIST processing logic depends on the type of server connected. The following are examples of what is tested.

• Global Positioning System (GPS)

• Fluxgate Compass

• DSP Card

• Clock/Ref Card

• A/D & NBT Card

• Audio Switch Card

• A/D & I/O Card

• HF Chassis

• HF DF Receiver

• RF/IF MUX Card (IF portion)

• HF Metrics Receiver

• HF DF Switch

• HF Antenna

• VHF Receiver

• UHF DF Switch

• RF/IF MUX Card (RF portion)

• UHF Antenna

• VHF DF Switch

• VHF Antenna

When running BIST and an error is detected, an error message is displayed on the Scorpio Client display. Errors can occur for various reasons such as equipment failures, software errors, and others.

Scorpio Client Database Maintenance

The Scorpio Client application uses a Microsoft Access database (ScorpioClient.mdb) to store data retrieved from the Scorpio Servers. There is a size limit of 2GB imposed by Microsoft.

The ScorpioClient.mdb file should be compacted and repaired occasionally. This can be done manually (as described below), or it can be scheduled to happen at regular intervals using the Windows Task Scheduler (please refer to the Windows Help for more information). Create a batch file (which is a text document with a .bat extension) with the command-line to compact and repair the database; run the .bat file as the scheduled task.

The .bat file should look something like: “path_to_msaccess.exe” “C:\Program files\TCIBR\Scorpio Client\Database\ScorpioClient.mdb”/compact

An example of the batch file is listed below (just make sure the path to the msaccess.exe is correct for the workstation).

Figure B-1 Remote DFLS Subnet

The Scorpio Router treats the RSMS as a client, accepting requests. These requests are in the form of messages. The following request messages are accepted by the Scorpio Router: "Connection Request," "Station List Request," "Station Connect Request," and "Bearing Request." The Scorpio Router shall send appropriate response messages (back) to the RSMS for the "Station List Request," "Station Connect Request," and the "Bearing Request." There is no response to the "Connection Request."

A communications module is provided that allows the DFLS to be tasked from other systems. The router module shall reside on the CC Workstation computers. This router module shall use the TCP/IP protocol and shall provide a service socket interface to all external users. Once a connection is established, the external user may maintain this connection for as long as is required.

The router service shall provide the interface service using TCP/IP port number 2732. The router service application shall wait for connections from external users. Once a connection is

established, the user shall request a list of stations from the router. Only those stations to which the router application has been successfully connected will be available to the external users for bearing requests. External users can send a Station Connect Request to try to enable a connection between the Router and a DF station. The user will then have the ability to task the DF network as described below.

The typical sequence of events is as follows: 1. Send "Connection Request" message.

2. Send "Station List Request" message to determine if the desired station is currently connected to the Scorpio Router.

3. If the desired station(s) is not currently connected, send a "Station Connect Request" message for each station. The router will attempt to connect to the station(s) over WAN. When connecting a new station, the response message will be returned only after the station is successfully connected, or after it times out (approx. 3.5 minutes). When a station is connected, the Scorpio Router will maintain the WAN link until it is disconnected with the appropriate message.

4. When all desired stations are connected, send "Bearing Request" message to desired stations. 5. When finished requesting bearings, send a "Station Connect" message to the appropriate stations

to disconnect them. The Scorpio Router does not queue DF requests. If a bearing measurement is in progress, a Busy

message will be returned. The message structures utilize the data types listed in the table below. These data types are taken from

the standard C++ language structures used to produce the message transport elements. The data types also take into account the fact that the Communications Router is hosted on Windows, A 32-bit operating system. This description does not take into account any big/little endian issues that may arise due to inter-platform message passing. It is the responsibility of the developer to ensure that the data passed to the Communication Router arrives with standard IBM PC representation of the data types.

Message: Connection Request

• Description: This message is used to obtain a connection to the DFLS System. This must be the first message received from a client after a TCP/IP connection is established; any other message is viewed by the router as an invalid connection request. There is no response to this message. If the connection request message succeeds, the TCP/IP connection remains open. If the process fails, the connection is dropped and the service closes Scorpio Client socket.

APPENDIX D TCI LICENSE FILE DATA FORMAT AND REQUIREMENTS

License File Format

The license file used to import license data into the TCI Scorpio applications possesses the following attributes:

• The file is an ASCII text file with a .LIC file extension

• Each line in the file describes one license.

• Each line in the file ends with a carriage-return and a line-feed character pair (ASCII “0D 0A”).

• There are 14 fields associated with each license, delimited by a semicolon ";" character. Each of these fields is described in Table D-1.

• Any field may contain a "null" (i.e., nil data), however those fields marked as "Yes" in the "AVD Req’d" column in Table 1 must contain valid and accurate data if Automatic Violation Detection (AVD) functionality is to be used.

• Semicolons must not be present within the license data.

The following line of text is a valid example of one license/line definition within a license file: 140;A007;Fixed;123;2000;102500000;1;200000;360;CONATEL;KDONFM;36.7564;-121.501421;A

Creating a License File Using Microsoft Excel

These instructions were generated using Microsoft Excel 2000. The instructions may vary slightly if using a different version of Excel, however the same concepts are applicable.

Warning: The following steps assume that commas are not used within the license data.

The following describes how an operator can create a license file from an Excel (.XLS) spreadsheet file suitable for importing into Scorpio Client.

1. Populate spreadsheet with license data: Create an empty Excel .xls spreadsheet file and add the license data described in Table D-1 into each column.

• If there is no data for a field, a "space" must be added in the column (press the <spacebar> key on the keyboard to insert a "space"). Every license must contain some value for columns 1 through 14. This value can be either actual license data (if available) or a "space." (If data or a space is absent for any fields, the subsequent steps will fail to have the correct number of delimiters inserted.)

• Be sure to enter the Latitude and Longitude data as decimal degrees. For example, 23.97083333 and 120.96250000. If you set Latitude as “23N5815,” this can easily be converted to decimal notation by Excel. In different cells, extract the degrees part (“23”), the direction ("N"), the minutes part ("58") and the seconds part ("15") by using the LEFT( ) and RIGHT( ) worksheet functions.

Latitude conversion example: For example, assume that the latitude "12N5815" is in cell A1. Place each of the following in the cells

B1 through F1: Cell B1: To extract the degrees part use “=LEFT(A1, 2).” This results in the extraction of the value "12."

Cell C1: To extract the direction part use “=LEFT(RIGHT(A1,5),1)”. This results in the extraction of the value "N."


D-3

Cell D1: To extract the minutes part use “=LEFT(RIGHT(A1,4),2)”. This results in the extraction of the value "58."

Cell E1: To extract the seconds part use “=RIGHT(A1,2)”. This results in the extraction of the value "15."

Cell F1: Add the following formula to convert to decimal degrees: “=IF(T(C1)="N",(B1+(D1/60)+(E1/3600)), -(B1+(D1/60)+(E1/3600))).” This results in the extraction of the value “23.9708333.”

Longitude conversion example: For Longitude conversion, assume "120E5745" is in cell G1. Place each of the following in the cells

H1 through L1: Cell H1: To extract the degrees part use “=LEFT(G1, 3).” This results in the extraction of the value "120."

Cell I1: To extract the direction part use “=LEFT(RIGHT(G1,5),1). This results in the extraction of the value "E."

Cell J1: To extract the minutes part use “=LEFT(RIGHT(G1,4),2). This results in the extraction of the value "57."

Cell K1: To extract the seconds part use “=RIGHT(G1,2). This results in the extraction of the value "45."

Cell L1: Add the following formula to convert to decimal degrees: “=IF(T(W79)="E",(V79+(X79/60)+(Y79/3600)) ,-(V79+(X79/60)+(Y79/3600)))”. This results in the extraction of the value “120.96250000”

The above steps will have succeeded in converting both latitude and longitude into decimal degrees.

2. Validate data: Verify that the Excel spreadsheet contains data (or a space) in every row for each of columns 1 through 14.

3. Save file as CSV: From the menu, select “File, Save As.” In the “Save As Type” dropdown list, select “CSV” (Comma Separated Variable) and press the <Save> button. A message requesting the following will then appear: “file.csv may contain features that are not compatible with CSV (Comma delimited). Do you want to keep the workbook in this format?” Press the <Yes> button. Close Excel, and if asked to “Save changes to file.csv?” Press the <No> button.

4. Edit the file using a text editor: Open the newly created file.csv file using a text editor such as WordPad, and replace all commas with semicolons, and replace all spaces with nulls:

Replace all commas with semicolons: From the menu select "Edit, Replace…".

• In the "Find what" box, enter a comma ",".

• In the "Replace with" box, enter a semicolon ";".

• Press the <Replace All> button.

• Press <Ok> when the replacements are finished.

• Press the <Cancel> button to close the "Replace" dialog.


D-4

Replace all spaces with nulls: For example, from the menu select "Edit, Replace…".

• In the “Find what:” box enter a "space" (press the <spacebar> key on the keyboard).

• Ensure the “Replace with:” box is empty.

• Press the <Replace All> button.

• Press <Ok> when the replacements are finished.

• Press the <Cancel> button to close the "Replace" dialog.

5. Save file: When asked “You are about to save the document in a Text-Only format, which will remove all formatting. Are you sure you want to do this?” Press the <Yes> button. Close WordPad.

6. Rename file: Rename from file.csv to file.lic.

7. Import license file into Scorpio: The file.lic file can now be imported into Scorpio Client by pressing the <Import> button in the AVD screen

APPENDIX E TCI SERVICE BAND FILE DATA FORMAT AND REQUIREMENTS

Service Band File Format

The service band file used to import service band data into the TCI Scorpio applications possesses the following attributes:

• The file is an ASCII text file with a .FRG file extension

• Each line in the file describes one service band.

• Each line in the file ends with a carriage-return and a line-feed character pair (ASCII “0D 0A”).

• There are 9 fields associated with each service band, delimited by a semicolon ";" character. Each of these fields is described in Table E-1.

• Any field may contain a "null" (i.e., nil data), however those fields marked as "Yes" in the "AVD Req’d" column in Table 1 must contain valid and accurate data if Automatic Violation Detection (AVD) functionality is to be used.

• Semicolons must not be present within the service band data.

The following line of text is a valid example of one service band/line definition within a service band file:

1;FM;88.1;108.0;;;0.002;0.2;FM Broadcast Band
