Response to Query
Rx Frequency RFQ= 9 bytes Command or Query.
Rx Frequency
CDM-570L: 950 to 1950 MHz
CDM-570: 50 to 90 and 100 - 180 MHz
Resolution=100 Hz
Example: RFQ=0950.9872
Example: RFQ=0073.4528 RFQ=
RFQ?
RFQ*
RFQ# RFQ? RFQ=xxxx.xxxx
(see description of
arguments)
Rx FEC Type RFT= 1 byte, value
of 0 thru 6 Command or Query.
Rx FEC Type, where:
0=None (uncoded – no FEC) with differential encoding ON
1=Viterbi
2=Viterbi + Reed-Solomon
3= Reserved – do not use
4= Reserved – do not use
5=TCM + Reed-Solomon
6=Turbo
7= TPC/LDPC (Future option)
Example: RFT=1 (which is Viterbi only)
RFT=
RFT?
RFT*
RFT#
RFT+ RFT? RFT=x
(same format
as command argument)
Rx Demod
type RMD= 1 byte, value
of 0 thru 5 Command or Query.
Rx Demodulation, where:
0=BPSK
1=QPSK
2=OQPSK
3=8PSK
4=16QAM (Turbo or Viterbi + RS only)
5=8-QAM (Future option)
Depending on FEC type, not all of these selections will be valid.
All other codes are invalid.
Example: RMD=2 (selects OQPSK)
RMD=
RMD?
RMD*
RMD#
RMD+ RMD? RMD=x
