Remote command:
:SENSe<ch>[:POWer]:FILTer:SONCe
Noise Content
For "Filter > Fixed Noise", sets the noise content.
Remote command:
:SENSe<ch>[:POWer]:FILTer:NSRatio
Timeout
For "Filter > Fixed Noise", sets a time limit for the averaging process.
Remote command:
:SENSe<ch>[:POWer]:FILTer:NSRatio:MTIMe
Use Default Aperture Time
The sensor default setting is sufficient. Disable this parameter to specify a user-defined
aperture time per sensor, if for example the readings vary.
To obtain stable readings, set the
Remote command:
:SENSe<ch>[:POWer]:APERture:DEFault:STATe
Aperture Time
If "Use Default Aperture Time" > "Off", defines the acquisition time per sensor.
For example, to obtain a sufficient low average value, set the aperture time exactly to
one modulation period.
Remote command:
:SENSe<ch>[:POWer]:APERture:TIMe
Use SParameter
Activates the use of the S-Parameter correction data of the connected power sensor.
For sensors with attenuator, this checkbox is automatically checked.
Refer to the manual of the connected R&S NRP power sensor for a description of how
to use the SParameter table.
Remote command:
:SENSe<ch>[:POWer]:CORRection:SPDevice:STATe
Enable Logging
Activates recording of R&S NRP power sensor readings in a log file.
There is 1 log file per sensor. The log files are created automatically and filled in con-
tinuously. They are text files with predefined filename SensLog<n>.txt, where <n>
indicates the connected sensor. Log files are stored on the hard disk, in the direc-
tory /var/sgt/temp/SensorLogging.
