The instrument shows the type of sensor, the used connector, the measurement
source and, if set, the offset.
You can activate the permanent display for several sensors.
Remote command:
:SENSe<ch>[:POWer]:DISPlay:PERManent:STATe on page 819
Priority ← Display ← Sensor Settings
Sets the display of results on mean or peak power.
Remote command:
:SENSe<ch>[:POWer]:DISPlay:PERManent:PRIority on page 819
Use Frequency Of ← Sensor Settings
Selects the source for measurement.
"RF"
Assigns one of the RF signals of the R&S SMW.
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.
You can also allocate two sensors in one path, for example to mea-
sure the power before and after the DUT.
"User"
Selects any freely selectable signal source, for example to measure
the amplifier gain with 2 sensors.
Set the parameter Frequency to the measurement's frequency.
Remote command:
:SENSe<ch>[:POWer]:SOURce on page 824
Frequency ← Sensor Settings
Defines the frequency value if "Source > User" is used.
Remote command:
:SENSe<ch>[:POWer]:FREQuency on page 822
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 on page 823
:SENSe<ch>[:POWer]:OFFSet:STATe on page 823
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 543.
