CALCulate<1|2>:DELTamarker<1 to 4>:FUNCtion:FIXed:RPOint:Y:OFFSet <numeric_value>
This command defines an additional level offset for the measurement with fixed reference value
(CALCulate:DELTamarker:FUNCtion:FIXed:STATe ON). For this measurement, the offset is
included in the display of all delta markers of the selected measurement window.
For phase-noise measurements (CALCulate:DELTamarker:FUNCtion:PNOise:STATe ON),
the command defines an additional level offset which is included in the display of delta marker 2 in
the selected measurement window.
Example: "CALC:DELT:FUNC:FIX:RPO:Y:OFFS 10dB"
'Sets the level offset for the measurement with fixed reference
'value or the phase-noise measurement in screen A to 10 dB.
Characteristics: *RST value: 0 dB
SCPI: device-specific
Mode: A
CALCulate<1|2>:DELTamarker<1 to 4>:FUNCtion:FIXed:RPOint:X <numeric_value>
This command defines a new reference frequency (span > 0) or time (span = 0) for all delta markers
in the selected measurement window for a measurement with fixed reference value
(CALCulate:DELTamarker:FUNCtion:FIXed:STATe ON).
For phase-noise measurements (CALCulate:DELTamarker:FUNCtion:PNOise:STATe ON),
the command defines a new reference frequency or time for delta marker 2 in the selected
measurement window.
Example: "CALC2:DELT:FUNC:FIX:RPO:X 128MHz" 'Sets the reference frequency in
'screen B to 128 MHz.
Characteristics: *RST value: - (FUNction:FIXed[:STATe] is set to OFF)
SCPI: device-specific
Mode: A
CALCulate<1|2>:DELTamarker<1 to 4>:FUNCtion:PNOise[:STATe] ON | OFF
This command switches on or off the phase-noise measurement with all actíve delta markers in the
selected measurement window. 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 commands CALCulate:DELTamarker
:FUNCtion:FIXed:RPOint:X and ...:RPOint:Y independently of the position of marker 1 and
of a trace (the same commands used for the measurment with fixed reference point).
The numeric suffix <1 to 4> with DELTamarker is not relevant for this command.
Example: "CALC:DELT:FUNC:PNO ON" 'Switches on the phase-noise measurement
'with all delta markers in screen A.
"CALC:DELT:FUNC:FIX:RPO:X 128 MHZ" 'Sets the reference frequency
'to 128 MHz.
"CALC:DELT:FUNC:FIX:RPO:Y 30 DBM" 'Sets the reference level to
'+30 dBm
Characteristics: *RST value: OFF
