Example:
CALC:MARK:FUNC:DEM:SEL FM
Manual operation: See "Modulation" on page 517
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation[:STATe] <State>
This command turns the audio demodulator on and off when the measurement rea-
ches a marker position.
Parameters:
<State> ON | OFF
*RST: OFF
Example:
CALC:MARK3:FUNC:DEM ON
Switches on the demodulation for marker 3.
Manual operation: See "Marker Demodulation State" on page 516
[SENSe:]DEMod:SQUelch:LEVel <Threshold>
This command defines the threshold for selective demodulation.
All signals below the threshold are not demodulated.
Parameters:
<Threshold> Percentage of the display height.
Range: 0 to 100
*RST: 50
Example:
DEM:SQU:LEV 80
Sets the squelch level to 80% of the displayed signal.
Manual operation: See "Squelch level" on page 517
[SENSe:]DEMod:SQUelch[:STATe] <State>
This command turns selective demodulation at the marker position on and off.
For selective demodulation, the R&S FSW turns on a video trigger whose level corre-
ponds to the squelch level. Therefore it turns other triggers or gates off.
Parameters:
<State> ON | OFF
*RST: OFF
Example:
DEM:SQU ON
Signals below the level threshold are not sent to the audio out-
put.
Manual operation: See "Squelch" on page 517
