2 – QPSK
3 – OQPSK
4 – 8-PSK
5 – 16-QAM
6 – 8-QAM
U
Select the Rx spectral inversion type:
1 – Normal
2 – Inverted
I
Select the Rx data inversion type:
1 – Normal
2 – Inverted
B
Select the Rx descrambling type:
1 – Off
2 – On-Default
3 – On-IESS-315
W
Set an acquisition value in the range from 0 to 200 kHz (1 to 32 kHz if
symbol rate < 625 Ksymbol) ("" is implied).
F
Set an alarm point value in the range from 0.1 to 16.0 dB. If the E
below this value, the modem generates a receive traffic fault.
