Description of Arguments
Command or Query.
Rx Spectrum Invert, where:
0=Normal
1=Rx Spectrum Invert
Example: RSI=0 (selects Normal)
Command or Query.
Rx Descrambler state, where:
0=Off
1=Normal
2=IESS-315 when in Turbo mode
Example: RDS=1 (Scrambler On)
Command or Query.
Rx ± acquisition sweep range of demodulator, in kHz. Available
range depends on the symbol rate:
± 1 to the symbol rate (ksps)
18ksps to 32ksps:
± 1 to 32 kHz
32ksps to 389ksps:
389ksps to 2000ksps: ± 1 to 10% of sym rate
± 1 to 200 kHz
>2000ksps:
Example: RSW=009 (selects ± 9 kHz)
Command or Query.
Rx Clock Source, where:
0=Rx Satellite
1=Tx-Terrestrial
2=Internal(SCT)
3=INSERT (command valid only when Rx framing is Insert or
D&I++ and interface is G.703 or set for D&I loop.
Example: RCK=1 (selects Tx-Terrestrial)
Command or Query.
