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 | 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 547
14.8.3.15 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 14.8.2.7, "Programming
Example: Configuring a Spectrogram" , on page 1148.

Example: Basic Markers
This example demonstrates how to configure and define markers for a basic spectrum
measurement in a remote environment. It assumes that the basic frequency sweep
described in
Chapter 14.15.1, "Programming Example: Performing a Basic Frequency
Sweep" , on page 1375 has been performed and thus does not begin by presetting the
instrument.
