R&S FSQ Remote Control – Description of Commands
CALCulate:MARKer:FUNCtion:TOI[:STATe] ON | OFF
CALCulate Subsystem
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 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
CALCulate:MARKer:FUNCtion:ZOOM
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.
for phase noise mode
"CALC1:MARK1:FUNC:ZOOM 10"
'Zooms in around marker 1 by a factor of 10.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is an event and therefore has no *RST value and no query.
