CALCulate<1|2>:MARKer<1...4>:FUNCtion:TOI:MARKer CALCulate | SEARch
This command controls the positioning of the intercept markers 3 and 4 for TOI measurement, based
on the two carrier signals.
• CALCulate:
Calculates the intermodulation product frequencies.
• SEARch:
Performs a local peak search near the expected intermodulation product frequencies.
Example:
"CALC:MARK:FUNC:TOI:MARK SEAR"
' selects TOI marker search mode
Characteristics: *RST value: CALC
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1...4>:FUNCtion:TOI:RESult?
This command queries the third-order intercept point measurement 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 of this command.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK:FUNC:TOI ON"
'Switches the intercept measurement in screen A.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:FUNC:TOI: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:CENTer
This command sets the receiver or center frequency of the selected measurement window equal to the
frequency of the indicated marker.
If marker 2, 3 or 4 is selected and used as delta marker, it is switched to the marker mode.
Example:
"CALC:MARK2:FUNC:CENT"
'Sets the receiver frequency to the frequency of marker 2.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A-F
This command is an "event" and therefore has no *RST value and no query.
