Description of Arguments
to Query
Command or Query.
Rx Reed-Solomon decoding, where:
0=Normal (based on the Open Network framing mode selected)
1=IESS-310 mode Available all framing modes, except
EDMAC.
2=EF Data legacy standard (225,205) – unframed only
3=IBS (126,112) – unframed only
Note: Available in all framing modes, except EDMAC.
(This is a 'don't care' if no RS is selected in FEC type)
Example: RRS=0 (selects Normal)
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=On
2=IESS-315 when in Turbo mode
2=Special when uncoded or Viterbi (needs FAST Special Option
1 installed
Example: RDS=1 (Scrambler On)
Command or Query.
Invert Receive Data, where:
0=Normal
1=Inverted
Example: IRD = 1 (selects Inverted RX Data)
Command or Query.
Rx ± acquisition sweep range of demodulator, in kHz, ranging
from ± 1 to ± 32 kHz.
Example: RSW=09 (selects ± 9 kHz)
