Example: SENS1:FILT:TYPE AUTO
selects auto filter mode for the power sensor connected to the
SENSOR connector.
SENS1:FILT:LENG:AUTO?
queries the automatically set filter length.
Response: 1024
Usage: Query only
Manual operation: See "Filter Length" on page 239
:SENSe<ch>[:POWer]:FILTer:LENGth[:USER] <User>
The command selects the filter length for user filter mode (
SENSe:POWer:FILTer:
TYPE USER
). As the filter length works as a multiplier for the time window, a constant
filter length results in a constant measurement time. Values 1 and 2^n are settable.
The time window is fixed to 20 ms.
Parameters:
<User> float
Range:
1 to 65536
*RST: 1
Example: SENS:FILT:TYPE USER
selects user filter mode.
SENS:FILT:LENG 16
sets a filter length of 16. The resulting measurement time is 640
ms (2x16x20 ms).
Manual operation: See "Filter Length" on page 239
:SENSe<ch>[:POWer]:FILTer:NSRatio <NSRatio>
The command defines the noise content for fixed noise filter mode
(
:SENSe<[1]...3>:POWer:FILTer:TYPE NSRatio
). This value determines the
proportion of intrinsic noise in the measured result.
Parameters:
<NSRatio> float
Range:
0.001 to 1
Increment: 0.001
*RST:
0.01
Example: SENS1:FILT:TYPE NSR
selects fixed noise filter mode for the power sensor connected to
the SENSOR connector.
SENS1:FILT:NSR 0.2
sets a noise content of 0.2.
Manual operation: See "Noise Content" on page 239
