R&S ESU Remote Control – Description of Commands
CALCulate Subsystem
CALCulate<1|2>:MARKer<1...4>: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 single-
sweep mode.
The numeric suffix <1...4> 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<1|2>:MARKer<1...4>:FUNCtion:TOI[:STATe] ON | OFF
This command initiates the measurement of the third-order intercept point.
A two-tone signal with equal carrier levels is expected at the RF input of the instrument. Marker 1 and
marker 2 (both normal markers) are set to the maximum of the two signals. Delta marker 3 and delta
marker 4 are positioned to the intermodulation products. The delta markers can be modified separately
afterwards with the commands CALCulate:DELTamarker3:X and CALCulate:DELTamarker4:
X.
The third-order intercept is calculated from the level spacing between the normal markers and the delta
markers.
The numeric suffix <1...4> of :MARKer is irrelevant for this command.
Example: "CALC:MARK:FUNC:TOI ON"
'Switches on the measurement of the third-order intercept in screen A.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
