: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:
<Type>
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).

*RST:AUTO
Example: SENS:FILT:TYPE AUTO

selects automatic filter selection.

Manual operation: See "Filter"
