R&S ESU Remote Control – Description of Commands
CALCulate Subsystem
6.56 Operating Manual 1302.6163.12 - 03
CALCulate<1|2>:MARKer<1...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...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:MARK2:FUNC:NOIS ON"
'Switches on noise measurement for marker 2.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK2:FUNC: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...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...4 are irrelevant.
Example:
"CALC:MARK:FUNC:DEM:SEL FM"
Characteristics: *RST value: AM
SCPI: device-specific
Mode: A
In receiver mode the audio demodulator is controlled by the
SENSe:DEMod
sub-
system.
