CALCulate<1|2>:DELTamarker<1 to 4>:FUNCtion:FIXed[:STATe] ON | OFF
This command switches the relative measurement to a fixed reference value on or off. Marker 1 will
be activated previously and a peak search will be performed, if necessary. 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 to
:RPOint:Y independently of the position of marker 1 and of a trace. It is valid for all delta markers
in the selected measurement window as long as the function is active.
Example: "CALC2:DELT:FUNC:FIX ON" 'Switches on the measurement with fixed
'reference value for all delta markers in
'screen B.
"CALC2:DELT:FUNC:FIX:RPO:X 128 MHZ" 'Sets the reference frequency
'in screen B to 128 MHz.
"CALC2:DELT:FUNC:FIX:RPO:Y 30 DBM" 'Sets the reference level in
'screen B to +30 dBm
Characteristics: *RST value: OFF
SCPI: device-specific.
Mode:A
CALCulate<1|2>:DELTamarker<1 to 4>:FUNCtion:FIXed:RPOint:MAXimum[:PEAK] <numeric_value>
This command sets the reference point level for all delta markers in the selected measurement
window for a measurement with fixed reference point (CALC:DELT:FUNC:FIX:STAT ON) to the peak
of the selected trace.
For phase-noise measurements (CALCulate:DELTamarker:FUNCtion:PNOise:STATe ON), the
command defines a new reference point level for delta marker 2 in the selected measurement
window.
Example: "CALC:DELT:FUNC:FIX:RPO:MAX"
Characteristics: *RST value: -
SCPI: device-specific
Mode:A
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:DELTamarker<1 to 4>:FUNCtion:FIXed:RPOint:Y <numeric_value>
This command defines a new reference point level for all delta markers in the selected measurement
window for a measurement with fixed reference point.
(CALCulate:DELTamarker:FUNCtion:FIXed:STATe ON).
For phase-noise measurements (CALCulate:DELTamarker:FUNCtion:PNOise:STATe ON),
the command defines a new reference point level for delta marker 2 in the selected measurement
window.
Example: "CALC:DELT:FUNC:FIX:RPO:Y -10dBm" 'Sets the reference point level for
'delta markers in screen A to -10
'dBm.
Characteristics: *RST value: - (FUNction:FIXed[:STATe] is set to OFF)
SCPI: device-specific
Mode:A
