Continuous Value Update
If activated, the power sensor data is updated continuously during a sweep with a long
sweep time, and even after a single sweep has completed.
This function cannot be activated for individual sensors.
If the power sensor is being used as a trigger (see " Using the power sensor as an
external trigger " on page 370), continuous update is not possible; this setting is
ignored.
Remote command:
[SENSe:]PMETer<p>:UPDate[:STATe]
on page 678
Select
Selects the individual power sensor for usage if power measurement is generally acti-
vated (
State function).
The detected serial numbers of the power sensors connected to the instrument are
provided in a selection list. For each of the four available power sensor indexes
( "Power Sensor 1" ... "Power Sensor 4" ), which correspond to the tabs in the configu-
ration dialog, one of the detected serial numbers can be assigned. The physical sensor
is thus assigned to the configuration setting for the selected power sensor index.
By default, serial numbers not yet assigned are automatically assigned to the next free
power sensor index for which "Auto Assignment" is selected.
Alternatively, you can assign the sensors manually by deactivating the "Auto" option
and selecting a serial number from the list.

Zeroing Power Sensor
Starts zeroing of the power sensor.
For details on the zeroing process refer to "How to Zero the Power Sensor"
on page 372.
Remote command:
CALibration:PMETer<p>:ZERO:AUTO ONCE
on page 673
Frequency Manual
Defines the frequency of the signal to be measured. The power sensor has a memory
with frequency-dependent correction factors. This allows extreme accuracy for signals
of a known frequency.
Remote command:
[SENSe:]PMETer<p>:FREQuency
on page 675
Frequency Coupling
Selects the coupling option. The frequency can be coupled automatically to the center
frequency of the instrument or to the frequency of marker 1.
