Remote command:
:SENSe<ch>[:POWer]:SOURce
on page 337
Frequency
Defines the frequency value if "Source > User" is used.
Remote command:
:SENSe<ch>[:POWer]:FREQuency
on page 335
Level Offset
Activates and defines a level offset which is added to the measured value. The level
offset value is always expressed in dB, irrespective of the selected unit for result dis-
play.
This function allows you to consider for example an attenuator in the signal path.
Remote command:
:SENSe<ch>[:POWer]:OFFSet

Filter
Selects the way the length of the used filter is defined.
See also "About the measuring principle, averaging filter, filter length, and achieving
stable results" on page 222.
"Auto" The filter length is selected automatically and adjusted to the mea-
sured value. The value is indicated with the parameter
Filter Length
With high signals, the filter length and therefore the measurement
time can be short.
With low signal levels, the filter length and therefore the measure-
ment time is increased to reduce noise.
"User" The filter length is defined manually, with the parameter Filter Length .
As the filter length works as a multiplier for the time window, constant
filter length results in a constant measurement time.
Values 1 and 2N are allowed.
"Fixed Noise" The averaging factor is selected so that the sensor's intrinsic noise (2
standard deviations) does not exceed the specified noise content.
Set the noise content value with the parameter
Noise Content .
To avoid long settling times when the power is low, limit the averag-
ing factor with the parameter
Timeout .
Remote command:
:SENSe<ch>[:POWer]:FILTer:TYPE

Filter Length
For "Filter > Auto or User", indicates the used filter length.
