RM Receive Modulation Type (Config) (NV)
Use this command to set the modulation type for the demodulator.
RM <type>
Remote/front panel <type> parameter values are:
■
0/BPSK
■
1/QPSK (default)
From the front panel select:

RO Receive Offset Frequency (Monitor)
Use this command to view the frequency offset between the demodulator
synthesizer frequency setting (remote RS command or front panel RxIF
command) and the actual demodulator RxIF carrier frequency.
RO ?
The response is displayed in Hertz, typically within the range of ±30000 Hz;
however, measurement capabilities may extend past 30000 Hz. If the demodulator
is not locked to a receive signal, a remote ER 4 or front panel N/A response will
display.
From the front panel select:
Monitor > Rx Offset
RR Receive Symbol Rate (Config) (NV)
It is recommended that the PRD command be used rather than RR.
Use this nonvolatile configuration command to set the demodulator symbol rate.
RR <symbol sps>
<symbol sps> parameter values are symbol rates of 4800 through 2500000 sps
which correspond to rates of 4.8 ksps through 2.5 Msps. The default is 1544000.
