Configuration
6. Enter the data for the satellite that you want to use as a calibration reference. Note the
following calibration requirements:
Elevation angle: 5 – 70 degrees.
Not allowed for calibration: Inclined orbit.
Satellite identifier: GSC, NID, Orbital position (DVB-S, DVB-S2)

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