Auto Once
Searches the optimum filter length for the current measurement conditions. The result
is indicated with the parameter
Filter Length .
See also "About the measuring principle, averaging filter, filter length, and achieving
stable results" on page 222.
Remote command:
:SENSe<ch>[:POWer]:FILTer:SONCe
on page 334
Noise Content
For "Filter > Fixed Noise", sets the noise content.
Remote command:
:SENSe<ch>[:POWer]:FILTer:NSRatio
on page 333
Timeout
For "Filter > Fixed Noise", sets a time limit for the averaging process.
Remote command:
:SENSe<ch>[:POWer]:FILTer:NSRatio:MTIMe
on page 334
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 Aperture Time exactly to one modulation period.
Remote command:
:SENSe<ch>[:POWer]:APERture:DEFault:STATe
on page 331
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
on page 331
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
on page 332
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
.
