3. Enter the data for the satellite that you want to use as a calibration
reference. You can enter the satellite data manually or select a
satellite from the list of predefined satellites (Eutelsat). For satellite
information see
www.lyngsat.com.
Note the following calibration requirements:
Elevation cutoff: Not relevant for calibration.
Figure 6-3: Service profile for calibration
Satellite requirements for successful calibration
Elevation
Elevation angle: 5 — 70 degrees
Not allowed for calibration: Inclined orbit.
System encryption
DVB-S or DVB-S2
Polarisation
Horizontal or vertical polarisation.
Not allowed: Left-hand circular (L) or right-hand circular (R).
Symbol rate
The DVB symbol rate must be >5 Ms/s.
NID
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.
