[:SENSe]:DM:SQUelch <value>
[:SENSe]:DM:SQUelch?
Description: Sets the squelch power level. The squelch is applied to the NBFM
Cmd Parameters: <value>
Query Parameters: NA
Range: 0 dBm to -120 dBm or 1 fW to 1000000000000 fW
Default Value: -100 dBm or 100 fW or 2.24 μV
Default Unit: dBm or fW or fV
Example: To set the squelch to -10 dBm:
Front Panel Access: Setup, Squelch Lvl
16-44
Analyzer Summary Window, the NBFM Analyzer Audio Spectrum, and
the NBFM Audio Waveform on the front panel. If the Carrier power is
lower than the squelch level, the Audio Spectrum trace will drop to the
bottom of the graph, the Audio Waveform trace will stay in the middle
of the graph, and the all of the summary numerical values except for
Carrier Power will be dashed out. FETCh:SIGAnalyzer?,
READ:SIGAnalyzer?, and MEASure:SIGAnalyzer? will always
return all numerical values.
The query will be returned in the units (dBm, Watts, or Volts) selected
through the Rx Units button using the front panel or with the
command: UNIT:POWer:RX. If the Rx Units has been set to dBm, the
squelch setting is returned in dBm. If the unit is set to Watts, the
squelch setting is returned in fW. If the unit is set to Volts, the squelch
setting is returned in fV.
The set command is sent using the units selected with the Rx Units
button on the front panel or with the command: UNIT:POWer:RX. If the
Rx Units has been set to dBm, the squelch setting must be set in dBm.
If the unit is set to Watts, the squelch setting must be set in fW. If the
unit is set to Volts, the squelch setting must be set in fV.
