ALCulate<1|2>:DELTamarker<1...4>:FUNCtion:PNOise[:STATe]
This command switches on or off the phase–noise measurement with all active delta markers.
The correction values for the bandwidth and the log amplifier are taken into account in the
measurement.
Marker 1 will be activated, if necessary, and a peak search will be performed. If marker 1 is
activated, its position becomes the reference point for the measurement.
The reference point can then be modified with the
CALCulate<1|2>:DELTamarker<1...4>:FUNCtion:FIXed:RPOint:X and
CALCulate<1|2>:DELTamarker<1...4>:FUNCtion:FIXed:RPOint:Y commands
independently of the position of marker 1 and of a trace (the same commands used for the
measurement with fixed reference point).
The numeric suffixes <1|2> and <1...4> are irrelevant for this command.
Parameter
ON | OFF
Example
CALC:DELT:FUNC:PNO ON
Switches on the phase–noise measurement with all delta markers.
CALC:DELT:FUNC:FIX:RPO:X 128 MHZ
Sets the frequency reference to 128 MHz.
CALC:DELT:FUNC:FIX:RPO:Y 30 DBM
Sets the reference level to +30 dBm
Characteristics
RST value: OFF
SCPI: device–specific
Mode
A
CALCulate<1|2>:DELTamarker<1...4>:FUNCtion:PNOise:RESult?
This command queries the result of the phase–noise measurement. The measurement will be
switched on, if necessary.
The numeric suffixes <1|2> are irrelevant for this command.
This command is only a query and therefore has no *RST value.
Example
CALC:DELT:FUNC:PNO:RES?
Outputs the result of phase–noise measurement of the selected delta marker.
Characteristics
RST value: –
