R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
6.16 Operating Manual 1164.4556.12 - 06
CALCulate<1|2>:DELTamarker<1...4>:FUNCtion:PNOise:AUTO ON | OFF
This command adds an automatic peak search action for the reference fixed marker 1 at the end of
each particular sweep. This function may be used for tracking of a drifting source whilst phase noise
measurement. The delta marker 2 which shows the phase noise measurement result keeps the delta
frequency value. Therefore the phase noise measurement in a certain offset is valid although the
source is drifting. Only when the marker 2 is reaching the border of the span the delta marker value is
adjusted to be within the span. Choose a larger span in such situations.
Example:
"CALC:DELT:FUNC:PNO 1"
’Switches the phase noise measurement on.
“CALC:DELT:FUNC:PNO:AUTO ON”
’Activates the automatic peak search.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
The suffix at DELTamarker is ignored.
CALCulate<1|2>:DELTamarker<1...4>:FUNCtion:PNOise:RESult?
This command queries the result of the phase noise measurement in the selected measurement
window. The measurement will be switched on, if necessary.
Example:
"CALC:DELT:FUNC:PNO:RES?"
'Outputs the result of phase noise measurement of the selected delta marker in
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>:DELTamarker<1...4>:FUNCtion:PNOise[:STATe] ON | OFF
This command switches on or off the phase noise measurement with all active 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 measurement with fixed reference point).
The numeric suffix <1...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
SCPI: device-specific
Mode: A
