4.2 Checking the Eb/N0 and BER

Eb/N0 is an indication of how well the Outbound signal is being received by the VSAT. The BER (Bit Error Rate) shows the frequency of bits that are incorrect.

To verify the Eb/N0 and BER click Auto Eb/N0 Display (Figure 11).

Result: The Eb/N0 screen appears (Figure 12).

Figure 12: Eb/N0

The Eb/N0 value is color coded to represent the relative strength of the Outbound signal received as follows:

Green – the signal strength is in the normal range

Yellow – the signal strength is borderline

Red – the signal strength is weak

An acceptable value for the Channel BER is 10- E12 (10E-12).

4.3 CW Test Procedure

CAUTION

Do not perform this procedure unless instructed to do so by the hub operations staff.

The CW Test procedure is used to measure the VSAT’s transmission signal strength. The actual measurement is performed at the Hub. Normally, this test is initiated remotely from the Hub. In cases where the Hub Operator cannot initiate communication with the VSAT, it must be carried out from the remote siteTo perform the CW Test:

1. Switch the VSAT to OFF and then to ON.



12


Result: The VSAT goes into Boot mode (Figure 10).

2. Click Set Tech ID.

Result: The Technical ID form appears (Figure 13).

Figure 13: Technical ID – CW Mode

6. Appendix B – Support Software Installation and Operation

Gilat recommends that the Support software be installed on one PC at each client site. This software utility can be used by the hub operations staff, when operational difficulties are encountered, as a troubleshooting aid.

CAUTION

The Support and Installation software applications cannot be installed on the same PC. The troubleshooting software is found in both utilities and, if problems are encountered during the installation process, troubleshooting can be carried out using the software installation software.

6.1 Installation of the Support Software on the Client PC

CAUTION

The Support software can only be installed on one PC located behind the VSAT. If multiple PCs are connected via a mini-hub, for example, do not install the Support software on more than one of them.

To install the Skystar 360E Installation Software on the installer’s PC:

1. Insert the CD-ROM with the Support software in the CD-ROM drive of the client’s PC

2. Locate the Support Software icon (Figure 24) on the CD-ROM drive of the client’s PC and double-click on it.

CAUTION

This procedure should never be performed by the client unless specifically instructed to do so by the hub operator.

When the Help Desk software detects the Satellite modem going from Boot Mode to Operational Mode, it stores a copy of the VSAT parameters and stores them as an *.lpf file in the Registry. If the Satellite Modem parameters become “corrupted,” the Reconfigure VSAT procedure will send the stored parameters from the PC Registry to the Satellite Modem.

To reconfigure the Satellite Modem after receiving instructions to do so from the hub, click the Reconfigure VSAT button .

Result: The Satellite Modem parameters stored in the Registry are sent to the Satellite Modem.

7. Appendix C –Using the SatPointer device to Point the Antenna

NOTE

Contact your Gilat representative for more information about the SatPointer.

During the VSAT installation process at the remote site, the greatest difficulty is locating the satellite signal to enable the VSAT to lock onto the Outbound signal and communicate with the hub. In order to perform this operation, an external device is required.

The SatPointer is a small, lightweight alternative to using a Spectrum Analyzer or a field signal strength meter to calculate the optimum antenna position. The SatPointer is used in conjunction with the 360 or 360E VSAT to locate the DVB Outbound signal sent by the hub.

Figure 40: SatPointer

To set up the equipment to use the SatPointer:

1. Install the antenna and adjust the azimuth and elevation angles in accordance with the worksheet received from the hub.

2. Connect the coaxial cable labeled RF IN to the RF-IN connector on the VSAT.

3. Connect the other end of this coaxial cable to the LNB.

4. Connect the cable marked RF OUT to the RF OUT connector on the VSAT.

5. Connect the other end of this coaxial cable to the SatPointer Tx IN connector.

6. Connect the LAN cable to the LAN port on the laptop and then to the LAN port of the VSAT.

7. Ensure that the VSAT is configured to the Gilat network.

8. Power on the VSAT and verify the PC LED is lit on the front panel.

7.2 Maximizing the Satellite Signal Using the SatPointer

The SatPointer works by reading the DVB signal at the VSAT. As the antenna position is adjusted, the strength of the signal is indicated simultaneously in two different forms:

LCD display with Eb/N0 reading

Audio signal through speaker. The higher the pitch and strength of the sound, the higher the reading.

The optimal angle is achieved when each axis indicator is at its maximum value.

The LCD display has three types of readings:

A series of dashes indicates that the SatPointer is working but no signal is detected (Figure 42).

Figure 42: SatPointer: No Signal

Lo indicates that the SatPointer detects a low signal (Figure 43).

Figure 43: SatPointer: Low Signal

A number indicates the Eb/N0 reading detected (Figure 44).

Figure 44: SatPointer: Eb/N0 Reading



31


To maximize the satellite signal using the SatPointer:

1. Loosen the azimuth lock bolt and slowly rotate the antenna from side to side until you pass the maximum signal strength, as indicated on the SatPointer.

2. Set the antenna to the position where the SatPointer readings are at their highest, and tighten the azimuth lock bolt.

3. Loosen the elevation lock bolt and slowly rotate the antenna from side to side until you pass the maximum signal strength, as indicated on the SatPointer.

4. Set the antenna to the position where the SatPointer readings are at their highest, and tighten the elevation lock bolt.

5. Disconnect the coaxial cable from the SatPointer and connect the VSAT to the Tx IN connector of the Gilat ODU.

8. Appendix D - Creating a VSAT .lpf Installation File

This section describes how to create the .lpf installation file. The .lpf file is used during the VSAT software installation performed at the remote sites. A separate .lpf file must be created for each Inbound Band defined in the system. All VSATs belonging to a specific Inbound Band have identical configuration with the exception of their CPA number and the controlling HPS (HPP) ID.

The .lpf files should be created when all system parameters and at least one VSAT is configured on the NMS and all changes are committed.

To create the VSAT .lpf installation file:

1. On the NMS, right-click on the gray desktop area and select Workspace Menu This_Host.

Result: The NMS Terminal window opens.

2. Type cd /usat/nms/bin.

3. Type v360E_info lpf <VSAT CPA> <file name>.lpf

VSAT CPA – specify a CPA number of one of the VSATs defined in this Inbound band.

.lpf file name - specify the name of the .lpf file. The name must be followed by the .lpf file extension. The .lpf file name can be any alphanumeric combination.

Example:

In this example, the .lpf file is created for VSAT 1002. The name of the .lpf file to be created is “1002.lpf”. The following command is issued:

v360E_info lpf 1002 1002.lpf

Result: The contents of the created .lpf file is displayed followed by the Gilat prompt.

4. Type ls –al to verify that the .lpf file was successfully created.

5. Save the .lpf file to a diskette or transfer it to the Remote PC using FTP.

6. Distribute the .lpf file to VSAT installers.
