For more information see Chapter 3.3.3.4, "AF Demodulation", on page 296.
Marker demodulation is only available with option R&S FSV-B3 and is not available for
Spectrum Emission Mask measurements.
Mkr Demod On/Off ← Marker Demod
Switches the demodulation output on or off.
For more information see Chapter 3.3.3.4, "AF Demodulation", on page 296.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation[:STATe] on page 682
AM ← Marker Demod
Sets AM as the output demodulation mode. This is the default setting.
For more information see Chapter 3.3.3.4, "AF Demodulation", on page 296.
Remote command:
CALC:MARK1:FUNC:DEM:SEL AM, see CALCulate<n>:MARKer<m>:FUNCtion:
DEModulation:SELect on page 681
FM ← Marker Demod
Sets FM as the output demodulation mode. Default setting is AM.
For more information see Chapter 3.3.3.4, "AF Demodulation", on page 296.
Remote command:
CALC:MARK1:FUNC:DEM:SEL FM, see CALCulate<n>:MARKer<m>:FUNCtion:
DEModulation:SELect on page 681
Mkr Stop Time ← Marker Demod
Opens an edit dialog box to define how long demodulation should be output for span >
0.
For more information see Chapter 3.3.3.4, "AF Demodulation", on page 296.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:HOLDoff on page 681
Continuous Demod (span > 0) ← Marker Demod
Switches the continuous demodulation on or off. If the sweep time is long enough, the
set frequency range can be monitored acoustically.
For more information see Chapter 3.3.3.4, "AF Demodulation", on page 296.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:DEModulation:CONTinuous
on page 680
Squelch ← Marker Demod
Activates the squelch function, i.e. 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 269)
and deactivates any other trigger or gating settings. The squelch level and trigger level
are set to the same value.
