Configuring the RF Signal

"User"
Sets a user defined frequency.
Example:
If you have a frequency converting device between the generator and
the DUT. If the frequency converter doubles the frequency, you can
set twice the frequency in the R&S SMW. The R&S power sensor
considers this RF frequency setting.
Set the parameter Frequency to the measurement's frequency.
Remote command:
:SENSe<ch>[:POWer]:SOURce on page 902
Frequency ← Sensor Settings
Defines the frequency value if "Source > User" is used.
Remote command:
:SENSe<ch>[:POWer]:FREQuency on page 900
Level Offset State,Level Offset ← Sensor Settings
Activates and defines a level offset which is considered in the power meassurement
result. The level offset value is always expressed in dB, irrespective of the display of
the measurement result.
This function allows you to consider, for example, an attenuator in the signal path.
Remote command:
:SENSe<ch>[:POWer]:OFFSet on page 901
:SENSe<ch>[:POWer]:OFFSet:STATe on page 901
Filter ← Sensor Settings
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 586.
"Auto"
Selects the filter length automatically and adjusts it to the measured
value. The value is indicated with the parameter Filter Length.
When high output power is applied, the filter length and therefore the
measurement time can be short.
When low output power is applied, the filter length and therefore the
measurement time is increased which reduces the considered noise
content in your measurement.
"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.
