Cable calibration
1. On the page
SERVICE > Calibration
click
Start
in the section
Cable calibration
.
2. Wait for the calibration to finish (typically 2 minutes). After finished calibration a
message with the result of the calibration is displayed in the field
Result
.This 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.
It is recommended to make a cable calibration when servicing the system to check if the
antenna cable is still in good order.
3. After the azimuth and cable calibration switch on the modem. It will automatically
make a BUC calibration and is then ready.
4. When commissioning is completed, test all subscribed services.
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

Important
Make sure that the modem is not switched on at this point. The modem can
be switched on after the cable calibration.
