Remote command:
CALCulate<n>:PMETer<p>:RELative[:MAGNitude]
on page 1088
Use Ref Level Offset
If activated, takes the reference level offset defined for the analyzer into account for the
measured power (see
"Shifting the Display (Offset)" on page 457).
If deactivated, takes the Sensor Level Offset into account.
Remote command:
[SENSe:]PMETer<p>:ROFFset[:STATe]
on page 1092
Sensor Level Offset
Takes the specified offset into account for the measured power. Only available if Use
Ref Level Offset is disabled.
Remote command:
[SENSe:]PMETer<p>:SOFFset

Average Count (Number of Readings)
Defines the number of readings (averages) to be performed after a single sweep has
been started. This setting is only available if manual averaging is selected (
Meas Time/
Average setting).
The values for the average count range from 0 to 256 in binary steps (1, 2, 4, 8, …).
For average count = 0 or 1, one reading is performed. The general averaging and
sweep count for the trace are independent from this setting.
Results become more stable with extended average, particularly if signals with low
power are measured. This setting can be used to minimize the influence of noise in the
power sensor measurement.
Remote command:
[SENSe:]PMETer<p>:MTIMe:AVERage:COUNt

Duty Cycle
Sets the duty cycle to a percent value for the correction of pulse-modulated signals and
activates the duty cycle correction. With the correction activated, the sensor calculates
the signal pulse power from this value and the mean power.

Using the power sensor as an external trigger
If activated, the power sensor creates a trigger signal when a power higher than the
defined "External Trigger Level" is measured. This trigger signal can be used as an
external power trigger by the R&S
FSV/A.
This setting is only available in conjunction with a compatible power sensor.
For details on using a power sensor as an external trigger, see "Using a power sensor
as an external power trigger" on page 363.
