:SENSe<ch>[:POWer]:FILTer:TYPE <Type>
Selects the filter mode. The filter length is the multiplier for the time window and thus
directly affects the measurement time.
Parameters:
<Type> AUTO | USER | NSRatio
AUTO
Automatically selects the filter length, depending on the mea-
sured value. The higher the power, the shorter the filter length,
and vice versa.
USER
Allows you to set the filter length manually. As the filter-length
takes effect as a multiplier of the measurement time, you can
achieve constant measurement times.
NSRatio
Selects the filter length (averaging factor) according to the crite-
rion that the intrinsic noise of the sensor (2 standard deviations)
does not exceed the specified noise content. You can define the
noise content with command :SENSe<ch>[:POWer]:FILTer:
NSRatio.
Note: To avoid long settling times when the power is low, you
can limit the averaging factor limited with the "timeout" parame-
ter (:SENSe<ch>[:POWer]:FILTer:NSRatio:MTIMe).
*RST:
AUTO
Example: See Example "Performing a power measurement with a fixed fil-
ter" on page 548.
Manual operation: See "Filter" on page 243
:SENSe<ch>[:POWer]:FREQuency <Frequency>
Sets the RF frequency of the signal, if signal source "USER" is selected (:
SENSe<ch>[:POWer]:SOURce).
Parameters:
<Frequency> float
*RST: 1 GHz
Example:
:SENS1:SOUR USER
Selects user-defined source.
:SENS1:FREQ 2.44GHz
Sets the RF frequency of the source which is 2.44 GHz.
