6.2.8 Notch Filter
In some models that support the RF Preselector, such as PXE, there is also a notch
filter to suppress signals in the frequency band from 2.4 GHz to 2.5 GHz. This control
allows you to turn the notch filter on or off.
Remote Command
[:SENSe]:POWer[:RF]:RFPSelector:NFILter[:STATe] OFF | ON | 0 | 1
[:SENSe]:POWer[:RF]:RFPSelector:NFILter[:STATe]?
Example
:POW:RFPS:NFIL 1
:POW:RFPS:NFIL?
Dependencies Only appears when RF Input is selected as the Input
Only appears in models that support the notch filter, such as PXE. Attempting to turn it on or off via
SCPI in models that do not support it generates error message: -241 Hardware missing; Not available
for this model number
Only appears in measurements that support the Notch Filter, such as EMI Receiver measurements.
Attempting to turn it on or off via SCPI in measurements that do not support it generates error
message: -221, Settings conflict; Feature not supported for this measurement
In Frequency Scan measurement, this control is grayed-out when final measurement is running,
aligned with the RF Preselector key. The warning message “Function not available while measurement
is running” appears if the grayed-out control is pressed

Presel state
–
RF Presel: On, NF, when both RF Presel and Notch Filter are turned on
–
RF Presel: On, when RF Presel = on and Notch Filter= off
–
RF Presel: Off, when RF Presel = off
