R&S ESU Instrument Functions
Analyzer Mode
MKR STOP
TIME
The MKR STOP TIME softkey defines the stop time for demodulation at the
marker(s).
The R&S ESU interrupts the frequency sweep at the marker position and activates
the demodulation for the duration of the stop time (see also
MKR DEMOD ON/OFF ).
In the time domain (span = 0) the demodulation is continuously active irrespective of
the stop time set.
Remote command:
CALC:MARK1:FUNC:DEM:HOLD 3s
CONT DEMOD The CONT DEMOD softkey switches on the continuous demodulation in the fre-
quency domain. If the sweep time is long enough, the set frequency range can be
monitored acoustically.
Remote command:
CALC:MARK1:FUNC:DEM:CONT ON
4.8.11.7 Selecting the Trace
MKR
−>
TRACE
The MKR->TRACE softkey sets the active marker to different traces. Only those
traces can be selected which are visible on the screen in the same window.
The function of the softkey is identical to that of the softkey with the same name in
the
MKR-> menu.
Example
Three traces are displayed on the screen. The marker is always on Trace 1 on
switching on.
Remote command:
CALC:MARK:TRAC 2
[ MKR ->TRACE ] "1" The marker jumps to Trace 2, but remains at
the previous frequency or time.
[ MKR ->TRACE ] "3" The marker jumps to Trace 3.
