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
attenuation margin is left for the antenna cable. This indicates whether the antenna
cable and connectors are in good condition and well crimped.
The SAILOR XTR Ka is calibrated now. If the calibration failed there will be a message.
4.3.3 Manual OTC (BUC calibration) and GX modem access
This section describes manual OTC and modem access configuration.
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
