SENS:FILT:TYPE USER
selects user filter mode.
SENS:FILT:SONC
activates the search for the optimum filter length.
SENS:FILT:LENG?
returns the found optimum filter length.
Response: 128
Example:
EventUsage:
SENSe<ch>[:POWer]:FILTer:TYPE <Type>
The command selects the filter mode. The filter length is the multiplier for the time window
and thus directly influences the measurement time.
Parameters:
AUTO|USER|NSRatio
AUTO
The filter length is automatically selected depending on the
measured value. For high values, a short filter length is selected
and for low values a long filter length is selected.
USER
The filter length is set manually. As the filter length works as a
multiplier for the measurement time, this results in a constant
measurement time.
NSRatio
The filter lenghth (averaging factor) is selected so that the sensor's
intrinsic noise (2 standard deviations) does not exceed the
specified noise content. The desired noise content is entered with
command SENSe:FILTer:NSRatio.
To avoid very long settling times when the power is low, the
averaging factor can be limited with the Timeout parameter
(command SENSe:FILTer:NSRatio:MTIMe).
