Description of Arguments
to Query
Command or Query.
Rx FEC Code Rate, where:
0 = Rate 5/16 (Turbo Only)
1 = Rate 21/44 (Turbo Only)
2 = Rate 1/2
3 = Rate 2/3 (8-PSK TCM or 8-QAM only)
4 = Rate 3/4
5 = Rate 7/8
6 = Rate 0.95 (Turbo Only)
7 = Rate 1/1 (Uncoded or No FEC)
Depending on FEC and demodulation type, not all of these
selections will be valid.
Example: RCR=1 (selects Rate 3/4)
Command or Query.
Rx Data Rate, in kbps, between 2.4 kbps to 9.98 Mbps.
Resolution=1 bps
Example: RDR=2047.999
Query only.
Rx Symbol rate, in ksymbols/sec, between 4.8 ksps and 3.00 Msps
Resolution = 1 sps.
Example: RSR=2047.999 (which is 2047.999 ksymbols/sec)
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 (default descrambler type)
2 = On - IESS-315 (Turbo only)
Example: RDS=1 (Scrambler On)
