Marker Demodulation State
Activates or deactivates the demodulation output.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation[:STATe]
Continuous Demodulation
If activated, the signal is demodulated continuously (not only at the marker position)
and sent to the audio output. This allows you to monitor the frequency range acousti-
cally (assuming the sweep time is long enough).
For zero span measurements, demodulation is always active continuously.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:CONTinuous
Marker Stop Time
Defines how long the sweep is stopped at the marker position to output the demodula-
ted signal.
For zero span measurements, demodulation is always active continuously, regardless
of the marker stop time.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:HOLDoff
Modulation
Defines the demodulation mode for output (AM/FM). The default setting is AM.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:SELect
Squelch
Activates or deactivates the squelch function. If activated, the audible AF is cut off
below a defined threshold level. Thus, you avoid hearing noise at the audio output
when no signal is available.
The squelch function activates the video trigger function (see
and deactivates any other trigger or gating settings. The squelch level and trigger level
are set to the same value. The trigger source in the channel bar is indicated as "SQL"
for squelch. The squelch level is indicated by a red line in the diagram.

Remote command:
Squelch Level
Defines the level threshold below which the audible AF is cut off if squelching is
enabled. The video trigger level is set to the same value.
The squelch level is indicated by a red line in the diagram.
