Manual operation: See "Filter Length" on page 243
:SENSe<ch>[:POWer]:FILTer:NSRatio <NSRatio>
Sets an upper limit for the relative noise content in fixed noise filter mode (:
SENSe<ch>[:POWer]:FILTer:TYPE). This value determines the proportion of intrin-
sic noise in the measurement results.
Parameters:
<NSRatio> float
Range: 0.001 to 1
Increment: 0.001
*RST: 0.01
Example: See Example "Performing a power measurement with a fixed fil-
ter" on page 548.
Manual operation: See "Noise/Signal Ratio" on page 243
:SENSe<ch>[:POWer]:FILTer:NSRatio:MTIMe
<MTime>
Sets an upper limit for the settling time of the auto-averaging filter in the NSRatio
mode and thus limits the length of the filter. The filter type is set with command :
SENSe<ch>[:POWer]:FILTer:TYPE.
Parameters:
<MTime> float
Range: 1 to 999.99
Increment: 0.01
*RST: 4
Example: See Example "Performing a power measurement with a fixed fil-
ter" on page 548.
Manual operation: See "Timeout" on page 244
:SENSe<ch>[:POWer]:FILTer:SONCe
Starts searching the optimum filter length for the current measurement conditions. You
can check the result with command :SENS1:POW:FILT:LENG:USER? in filter mode
USER (:SENSe<ch>[:POWer]:FILTer:TYPE).
Example:
SENS1:FILT:TYPE USER
Selects user filter mode.
:SENS1:FILT:SONC
Activates the search for the optimum filter length.
:SENS1:FILT:LENG?
Returns the found optimum filter length.
