Response to Query
Rx Data Rate N/A 10 bytes Query Only.
Composite Rx Data rate, in kbps.
Resolution=1 bps.
Example: RDR=002047.999 (which is 2047.999 kbps)
RDR?
RDR*
RDR# RDR? RDR=xxxxxx.xxx
Redundancy
State RED= 1 byte Command or Query.
Unit returns the redundancy state of the unit, where:
0 = Offline
1 = Online
*** This command can be used to force the unit offline, this is done by
sending RED=0. This is only valid if redundancy mode is enabled. If
redundancy is not enabled, then RED=0 will return an error. The unit
cannot be forced online.
*** If the unit is not in redundancy mode, then the unit will always be online.
Example: RED=0 (force unit offline)
RED=
RED?
RED*
RED# RED? RED=x
(see description of
arguments)
Rx Frequency
Offset N/A 5 bytes Query only.
Unit returns the value of the measured frequency offset of the carrier being
demodulated. Values range from
± 0 to ± 100 kHz, 100 Hz resolution.
Returns 999999 if the demodulator is unlocked.
Example: RFO=+002.3 (which is + 2.3 kHz)
RFO?
RFO*
RFO# RFO? RFO=sxxx.x
Rx Frequency RFQ= 9 bytes Command or Query.
Rx Frequency (in MHz)
52 to 88 MHz, and 104 to 176 MHz (70/140 Modulator)
950 to 1950 MHz (L-Band Modulator)
Resolution=100Hz.
Example: RFQ=0950.0000
RFQ=
RFQ?
RFQ*
RFQ# RFQ? RFQ=xxxx.xxxx
Rx Frame Size N/A 1 byte Query Only.
Rx Frame Size Long/Short selection, where:
0=Short,
1=Long
Example: RFS =0 (which is Short FEC Frame Size)
Returns RFS=x if Demodulator unlocked.
This is automatically detected on demod acquisition.
N/A RFS? RFS =x
Rx FEC Type N/A 1 byte Query Only.
Rx FEC coding type, where:
1=LDPC
( FEC is dependent on the RX Mode Type.)
Example: RFT=1 (which is LDPC coding)
RFT?
RFT*
RFT# RFT? RFT=x
