R&S SMB100A
Example:
Usage:
Manual operation:
: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>
Example:
Manual operation:
: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>
