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 443
[SENSe:]DEMod:SQUelch[:STATe] <State>
This command turns selective demodulation at the marker position on and off.
For selective demodulation, the R&S FSV/A 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 | 0 | 1
OFF | 0
Switches the function off
ON | 1
Switches the function on
Example: DEM:SQU ON
Signals below the level threshold are not sent to the audio out-
put.
Manual operation: See "Squelch" on page 442
12.8.3.15 Programming examples for using markers and marker functions
Various programming examples on how to use markers and the special marker func-
tions are provided here.
The use of spectrogram markers is demonstrated in Chapter 12.8.2.7, "Programming
example: configuring a spectrogram" , on page 1167.
