R&S FSQ Remote Control – Description of Commands
CALCulate:MARKer:FUNCtion:DEModulation[:STATe] ON | OFF
CALCulate Subsystem
This command switches on or off the audio demodulator when the indicated marker is reached in the
selected measurement window. In the frequency domain (span > 0) the hold time can be defined at
the corresponding marker position with CALCulate:MARKer:FUNCtion: DEModulation:HOLD.
In the time domain (span = 0) the demodulation is permanently active.
Example: "CALC2:MARK3:FUNC:DEM ON"
'Switches on the demodulation for marker 3 in screen B.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
CALCulate:MARKer:FUNCtion:MDEPth:RESult?
This command queries the AM modulation depth in the indicated measurement window.
A complete sweep with synchronization to sweep end must be performed between switching on the
function and querying the measured value to obtain a valid query result. This is only possible in singlesweep
mode.
The numeric suffix of :MARKer is irrelevant for this command.
Example: "INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK:X 10MHZ"
'Sets the reference marker (marker 1) to the carrier signal at 10 MHz.
"CALC:MARK:FUNC:MDEP ON"
'Switches on the modulation depth measurement in screen A.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:FUNC:MDEP:RES?"
'Outputs the measured value of screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is only a query and therefore has no *RST value.
CALCulate:MARKer:FUNCtion:MDEPth[:STATe]
This command switches on the measurement of the AM modulation depth. An AM-modulated carrier
is required on the screen for correct operation. If necessary, marker 1 is previously activated and set
to the largest signal available.
The level value of marker 1 is regarded as the carrier level. On activating the function, marker 2 and
marker 3 are automatically set as delta markers symmetrically to the carrier to the adjacent maxima of
the trace.
If the position of delta marker 2 is changed, delta marker 3 is moved symmetrically with respect to the
reference marker (marker 1). If the position of delta marker 3 is changed, fine adjustment can be
performed independently of delta marker 2.
The R&S FSQ calculates the power at the marker positions from the measured levels.
