Response to Query
Rx Modulation
Type N/A 1 byte Query only.
Rx Modulation type, where:
0=QPSK
1=8PSK
2=Reserved
3=16APSK
4=32APSK
Example: RMD=1 (which is 8PSK)
*NOTE: This command is query-only because the demodulation type is
automatically detected, but if the unit is not locked, the query returns ‘x’.
RMD?
RMD*
RMD# RMD? RMD=x
Rx FEC Code
Rate N/A 1 byte Query only.
Rx Code Rate, where:
0 = Rate 3/4
1 = Reserved
2 = Rate 3/5
3 = Rate 4/5
4 = Rate 5/6
5 = Rate 8/9
6 = Rate 9/10
7 = Rate 2/3
8 = Rate 1/2
Example: RCR=0 (which is Rate 3/4)
*NOTE: This command is query-only because the code rate is
automatically detected, but if the unit is not locked, the query returns ‘x’.
RCR?
RCR*
RCR# RCR? RCR=x
