>
Signal Type:
OFF | QPSK | PI/4 QPSK | QAM16 | QAM32 | QAM64 | CW
>
Symbol Rate (ignored if CW is used):
16800, 33600, 67200, 84000,
151200, 168000
>
Backoff: in the range

Loss
to modify them
Note:
FEM Cable Loss setup functionality is not fully implemented yet. These two values,
“RX Cable Loss” and “TX Cable Loss” are intended to be employed in S-band systems. It
might be applied for L-band systems as well, in the future.
