Command or Query.
Sets or returns Rx Descrambler state in th form x, where:
0 = Off
1 = On (default descrambler type)
2 = On – IESS-315
Note: When CnC mode is ON, Rx Descrambler state is fixed as IESS-315.
Example: <0/RDS=1 (Scrambler On)
Command or Query.
Sets or returns Rx ± acquisition sweep range of demodulator in the form xxx,
where:
xxx = value, in kHz...
For CDM-570A – From ±1 to ±32 kHz (rates<625 ksym/second)
For CDM/R-570AL – From ±1 to ±200 kHz (rates ≥625 ksym/second)
Note: When the modem is in CNC mode (CNM>0) and Rx Symbol Rate<64ksps,
acquisition sweep range is limited from ±1 to ±(Rx_Symbol Rate / 2) kHz
Example: <0/RSW=009 (±9 kHz)
Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns Rx Filter Rolloff Factor in the form x, where:
0 = 0.35
1 = 0.12
Example: <0/RXA=0 (0.35 Tx filter rolloff factor)
