Remote command:
:SENSe<ch>[:POWer]:DISPlay:PERManent:STATe
Display ← Display ← Sensor settings
Sets the display of results on mean or peak power.
Remote command:
:SENSe<ch>[:POWer]:DISPlay:PERManent:PRIority
Use Frequency Of ← Sensor settings
Selects the source for measurement.
"RF"
The sensor measures the power of the RF signal at the current fre-
quency. It considers the correction factor and uses the level setting of
the instrument as reference level. Frequency variations are automati-
cally routed to the sensor.
"User"
Selects any freely selectable signal source, for example to measure
the amplifier gain with 2 sensors.
Set the parameter
to the measurement's frequency.
Remote command:
Frequency ← Sensor settings
Defines the frequency value if "Source > User" is used.
Remote command:
Level Offset State,Level Offset ← Sensor settings
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:STATe
Filter ← Sensor settings
Selects the way the length of the used filter is defined.

"Auto"
The filter length is selected automatically and adjusted to the mea-
sured value. The value is indicated with the parameter
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.
