Description of Arguments
Command or Query.
Invert Receive Data in the form x, where:
0=Normal
1=Inverted
Example: RDI=1 (selects Inverted RX Data)
Command or Query.
Rx RS decoding in the form x, where:
0=Normal (based on the Open Network framing selected)
1=IESS-310 mode, valid with QDI, unframed, IBS, D&I, IDR.
2=EF Data legacy standard (225,205) – unframed, QDI only
3=IBS (126,112) – unframed only
Note: Available in all framing modes, except EDMAC (this is a 'don't care' if no R-S is selected in FEC type)
Example: RRS=0 (selects Normal)
Command or Query.
Rx Spectrum Invert in the form x, where:
0=Normal
1=Rx Spectrum Invert
Example: RSI=0 (selects Normal)
Command or Query.
Rx Descrambler state in the form x, where:
0=Off
1=Normal
2=IESS-315
Example: RDS=1 (Scrambler On)
Command or Query.
Rx ± acquisition sweep range of demodulator, in kHz. Available range depends on the symbol rate:
18ksps to 64ksps: ± 1 to the symbol rate (ksps)/2
64ksps to 389ksps: ± 1 to 32 kHz
389ksps to 2000ksps: ± 1 to 10% of sym rate
>2000ksps: ± 1 to 200 kHz
Example: RSW=009 (selects ± 9 kHz)
