R&S ESCI CALCulate:MARKer Subsystem

CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:ZOOM <numeric_value>
This command defines the range to be zoomed around marker 1 in the selected measurement
window. Marker 1 is activated first, if necessary.
The subsequent frequency sweep is stopped at the marker position and the frequency of the signal is
counted. This frequency becomes the new center frequency, and the zoomed span is set. In order to
recognize the end of the operation the synchronization to the sweep end should be activated. This is
only possible in single sweep mode.
Example: "INIT:CONT OFF" 'Switches to single-sweep mode
"CALC:MARK:FUNC:ZOOM 1kHz;*WAI" 'Activates zooming in screen A and
'waits for its end.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A-F
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NOISe[:STATe] ON | OFF
This command switches the noise measurement on or off for all markers of the indicated
measurement window. The noise power density is measured at the position of the markers. The
result can be queried with CALCulate:MARKer:FUNCtion:NOISe:RESult?.
Example: "CALC2:MARK:FUNC:NOIS ON" 'Switches on the noise measurement for
'screen B.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NOISe:RESult?
This command queries the result of the noise measurement.
A complete sweep with synchronization to the sweep end must be performed between switching on
the function and querying the measured value in order to obtain a valid query result. This is only
possible in single sweep mode.
Example: "INIT:CONT OFF" 'Switches to single-sweep mode.
"CALC:MARK2 ON" 'Switches on marker 2 in screen A.
"CALC:MARK:FUNC:NOIS ON" 'Switches on noise measurement in screen A.
"INIT;*WAI" 'Starts a sweep and waits for the end.
"CALC:MARK2:NOIS:RES?" 'Outputs the noise result of marker 2 in
'screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:DEModulation:SELect AM | FM
This command selects the demodulation type for the audio demodulator. The command is
independent of the measurement window and of the selected marker, i.e. suffixes 1|2 and 1 to 4 are
irrelevant.
Example: "CALC:MARK:FUNC:DEM:SEL FM"
Characteristics: *RST value: AM
SCPI: device-specific
Mode: A
