For EMI measurements, the duration of the demodulation at each marker position is
limited by the dwell time of the EMI measurement marker (see "Dwell Time"
on page 303).
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:HOLDoff on page 965
Modulation
Defines the demodulation mode for output (AM/FM). The default setting is AM.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:SELect on page 965
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 "Video" on page 428)
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:
[SENSe:]DEMod:SQUelch[:STATe] on page 966
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.
Remote command:
[SENSe:]DEMod:SQUelch:LEVel on page 966
7.4.3.8 Marker Peak List Configuration
The marker peak list provides an overview of all marker peaks in the measurement.
You can define search and sort criteria to influence the results of the analysis. The
general marker search settings also apply to the marker peak list (see "Marker Search
Settings" on page 498).
For more information see chapter 7.4.1.4, "Searching for Signal Peaks", on page 486.
To display the "Marker Peak List" dialog, do one of the following:
●
Press the MKR FUNC key, then select the "Marker Peak List" softkey.
●
In the "Overview", select "Analysis", and switch to the vertical "Peak List" tab.
