5. Click Start and wait typically 5 minutes for the azimuth calibration to finish. A
message is displayed when the calibration has completed. In case of failure, see the
table in the following section for a description of error codes during calibration.
The following table shows the error codes that might be displayed during a calibration.
Cable calibration
You must make a cable calibration. It is also recommended to make a cable calibration
when servicing the system to check if the antenna cable is still in good order. If the
attenuator margin changes by 2 dB or more after a cable calibration, it is
recommended to do a P1dB compression measurement to verify that the VSAT
modem configuration is correct.
1. Select Service > Calibration.
2. In the section TX cable calibration, select the Type:
• Cable calibration: The system will make a complete cable calibration
(recommended).
• Disable TX cable calibration: The gain is set at a maximum and no cable
calibration is made. It is up to the modem to make the necessary adjustments.
3. Click Start.
4. Wait typically for 2 minutes for the calibration to finish. A message is displayed
when the calibration has been completed successfully.The screen shows how much
Important
It is strongly recommended to verify the result of a calibration
performed with user defined data. This can be done by making a new
calibration on a different satellite and verify that the resulting
Azimuth calibration value differs less than one degree.
Error code Explanation
1 The elevation of the selected satellite is too low. Select another
satellite.
2 The elevation of the selected satellite is too high. Select another
satellite.
4 The calibration values could not be saved. Possibly due to defective
hardware.
5 The antenna could not point with sufficient precision. Check that the
antenna is mounted in a stable way. Other possible causes might be
electrical or mechanical faults.
6 No signal received. Check that there is free line of sight. Try again or try
with another satellite.
7 RF setup error, e.g. missing or invalid TX frequency.
8 Invalid satellite, e.g. satellite not visible.
9 Unknown error
