Permanent ← Display ← Sensor Settings
Activates the permanent indication of the power measurement result in the task bar.
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 656
Use Frequency Of ← Sensor Settings
Selects the source for measurement.
"RF" The R&S SMBV100B transfers the RF frequency and level settings to
the R&S power sensor automatically. Thus you achieve power read-
ings of high accuracy, irrespective from the connected sensor type.
"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
SMBV100B. The R&S power sen-
sor considers this RF frequency setting.
Set the parameter Frequency to the measurement's frequency.
Remote command:
:SENSe<ch>[:POWer]:SOURce
on page 660
Frequency ← Sensor Settings
Defines the frequency value if "Source > User" is used.
Remote command:
:SENSe<ch>[:POWer]:FREQuency
on page 659
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

:SENSe<ch>[:POWer]:OFFSet:STATe

Filter ← Sensor Settings
Selects the way the length of the used filter is defined.

stable results" on page 396.
