3. Type in its tracking frequency, 19.707 GHz.
4. Select Satellite identifier: GSC, NID, Orbital position (DVB-S, DVB-S2)

.
5. Click Start and wait typically 5 minutes for the azimuth calibration to finish. A progress
bar is shown during calibration and 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.
Satellite Position Frequency Satellite identifier
GX1 –IOR 62.6 E 19.707 GHz GSC
GX2 –AOR 55 W 19.707 GHz GSC
GX3 –POR 179.6 E 19.707 GHz GSC
GX4 –IOR 56.6 E 19.707 GHz GSC
GX5 –EME 11.0 E 19.701 GHz GSC

The calibration function is not able to verify the correctness or precision of
the supplied longitude. It is therefore important to supply the correct
longitude including the first decimal.
1. Use Orbital position and NID if you want to use NID or orbital position or other KA band
satellites with DVB-S2 support. The DVB symbol rate must be >5 Ms/s. For NID use
preferably a unique NID (ONID). An azimuth calibration without NID can be useful in
regions where the satellite operators do not broadcast NID (US, China, Australia etc.). For
NID=0 the NID is not used when checking the satellite link. For NID 1 to 65535 the
supplied NID is matched against the Network ID broadcast by the satellite. For orbital
position the supplied longitude is matched with the orbital position broadcast by the
satellite. Not all service providers broadcast the orbital position.
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.
