Once the satellite adjusted, it is possible to see its spectrum.
- Press the Spectrum key : . The abscissa axis represents the frequencies and the ordinate axis the reception levels (in dBµV).
The spectrum displayed depends on the selected band and polarity.
Band
Low : 10 650MHz - 11 700MHz
High : 11 700MHZ - 12 750MHz
Polarity
Horizontal
Vertical
Notes :
- A transponder contains several.
- The transponder width changes : it can be 27MHz, 36MHz or 72MHz.

Inactive transponder
If a single transponder doesn’t synchronise (quality=0), it is possible that its frequency is not valid anymore (in satellite,
the used frequencies are regularly modified). Use the following sensitive keys to replace the non valid transponders by
active transponders.
The transponders of the different satellites are listed on websites that are regularly updated, like
. For the example with ASTRA 19.2°E :
