1 General Information
1.1 Introduction
This manual is the operation and maintance manual for the UFX7000A, UFX7900A,
UFX9000/A and J7000 series of Programmable Noise Generating Instruments. It
provides general information plus installation and operation instructions.
1.2 Description of the Basic Unit.
Noise Com, Inc. Series UFX7000A, UFX7900A, UFX9000/A and J7000 represent the
state of the art in Noise Generators. The Instrument can be controller manually by a touch
screen display or remotely via Ethernet, GPIB (IEEE 488) or RS232/RS422/RS423. The
instrument is controlled by a PC104 which provides for a very powerful and user friendly
instrument.
The instrument is 17.22 inches wide, 6.3 inches heigh and 19.5 inches deep. Rack
mounting brackets are optional, and can be fitted at the factory or later by the user.
The RF circuit, without options, is comprised of a noise source, a RF switch, and a
programmable attenuator. The remote interface for this unit with out any options is
Ethernet.

1.3 Options
Options avaliable on the Noise Generator Instruments include :-
GPIB (IEE 488)
Fine resolution attenuator, 0.1dB steps.
Input mains power 240V 50Hz.
Rack mounting brackets, to allow rack mounting into a 4U, 19” rack.
Switching the noise bandwidth by means of band limiting filters. These filters
can be internal or external to the instrument. The frequencies of interest are
specified by the customer. The maximum number of filters for a standard
instrument is 4. The box will be able to provide the full noise band width, the 4
filtered bands, and a terminated (RF off ) position.
Input connector and signal combiner. This allows an external signal to be
combined with the noise output. The noise output for this option is typically 6dB
lower than specified for a standard unit. A resistive combiner is used for low
frequency units (< 2GHz), and a Wilkinson combiner for the higher frequency
units (>2GHz).
A programmable attenuator can be added with the signal combiner option to give
the user amplitude control of the input signal. This attenuator can be 1dB or 0.1dB
steps.
Switched outputs. There is a SPDT RF switch at the output which allows the user
to switch between either of two outputs.

14 Plug for AC input supply.
3.2 Initialization
Turn the instrument on, press the power switch on the Front bottom left cover of
the box (refer item 1 of Figure 1). The LED in the switch will iluminate.
After loading windows, the instrument will load the application software. This
will take a few moments, you will see the screen change a few times.
The instrument is now ready for manual control via the touch screen or remote
control. In this state after power on, the RF state of the box will be, all attenuators
will be set to the last stored attenuation setting, and the RF switch will be set to
off. GPIB and Ethernet address setup will be discusses later in the manual.

4 Operation
4.1 Operation of Noise Attenuator, and Noise ON/OFF.
Figure 3 shows the start up screen for the UFX9937. The instrument can be fully
controlled using the touch screen interface. Figure 3 shows the screen once the unit has
booted up. {Note: the attenuation maybe different. Under normal shutdown the system
saves the last attenuation setting, and uses this as the start up setting}. The ON/OFF
indicates the state of the noise source. ON = Noise source is on, OFF = Noise Source is
off.

The UFX9937 is a touch screen device. Touching the buttons will allow you to control
that parameter.
To turn the Noise ON/OFF, simply touch the button labeled OFF in Figure 3.
Touching this button will turn the Noise source ON/OFF.
Changing the attenuation can be done by
1. Touching the up/down arrow keys. This will change the attenuation by a
programmable step size.
2. Touching the Atten (dB) value (79.0 in Figure 3) will open a keypad display
(refer Figure 4). In this display you can directly set the value of the
attenuation. In this screen you can also set the Step Size. Figure 5 shows the
window that sets the Step Size.

5 Setting Remote Control Addresses and Parameters
5.1 TCP-IP Address
The UFX9937 is controlled fully via Ethernet. The SCIPI commands are given in the
back of this manual. First the IP address needs to be set/allocated.
First push the Comm button from Figure 3. This will then change the options down the
side of the screen. From the updated menu choose TCP-IP. This will then give Figure 6.
To change the IP Address, push on the window displaying the IP Address number in
Figure 6. This will then change the display to Figure 7. On the top left side of Figure 7
there is a button marked DHCP (Dynamic Host Configuration Protocol). If this button is
GREEN, then DHCP is enabled, and the settings will be automatically selected from the
active DHCP server on the network. If this button is RED then DHCP is disabled, and the
settings will have to be set manually.
Once the IP Address is set, the UFX9937 should be soft shut down (using the Hibernate
button) and re-started.

5.2 GPIB
The UFX9000A is controlled fully via GPIB (Note GPIB is an option, U7opt16). The
SCIPI commands are given in the back of this manual. First the GPIB address needs to be
set.
First push the Comm button from Figure 3. This will then change the options down the
side of the screen. From the updated menu choose GPIB. This will then give Figure 8.
To change the GPIB Address, push on the window displaying the GPIB Address number
in Figure 8. This will then open a keypad window that will allow you to change the GPIB
address. EOS Char, is changed in the same manner. Time out is changed using the pull
down arrow beside the window.
To Enable/Disable the other GPIB specific options
Send EOI at End of Write
Terminate Read on EOS
Set EOI with EOS on Write
8-bit EOS Compare
Simply press on the Enable/Disable buttons shown in Figure 8 to change the setting.

6 Turning Off The Instrument The preferred method of turning the instrument off is to use the Hibernate button in
Figure 3. The Hibernate button is only accessible from this screen. Hibernate saves the
system settings, (e.g. Attenuation, ON/OFF) before the instrument shuts down. These
settings are restored when the instrument is started.
7 Software Up-Grades Software upgrades are avaliable on request. The upgrade is performed using the USB
port, and a flash drive. NOTE: Please read ALL the instructions before performing any
software installation on the instrument.
The following procedure is for installing the new UFX9000A software:
a. Power up the UFX9000A series instrument. When the user interface screen is
present on the instrument, insert the USB removable drive into the instruments
front panel USB socket.
b. Wait for the 'Noise/Com Software" Autorun dialog box to popup.
Note: We have observed that when using the USB removable drive for the first
time, the standard ‘plug-and-play’ messages appear in the lower right corner of
the display. This is normal. When the message reads ‘hardware is now ready...’ a
generic Autorun box appears. If this is your case, remove and reinsert the USB
removable drive from the instrument. The ‘Noise/Com Software’ Autorun dialog
should now appear.
c. Select "Upgrade Noise/Com UFX9000A Software using the program provided on
the device". Click "OK".
d. The "Noise/Com UFX9000A software upgrade version 1.12" dialog box should
appear. Click "OK".
e. The WinZip Self-Extraction dialog box will appear and automatically install the
new software.
f. This completes the software installation procedure.
g. Remove the USB removable drive from the UFX9000A instrument.
h. Cycle power. The user interface screen should now be present on the instrument.
The new software is now ready for use.

8 Repairs/Hardware Upgrades In the event that the UFX9000A instrument is not performing correctly, or additional
options are to be installed, contact Noise Com and get an RMA and shipping instructions.
If the original packing box for the UFX9000A is lost of discarded, please contact Noise
Com and a replacement box will be sent. It is important to ship the UFX9000A in the
appropriate packaging to prevent damage while the instrument is in transit.
