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.

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
FPL1000.
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 365.

External Trigger Level ← Using the power sensor as an external trigger
Defines the trigger level for the power sensor trigger.
For details on supported trigger levels, see the data sheet.
Remote command:
[SENSe:]PMETer<p>:TRIGger:LEVel

Hysteresis ← Using the power sensor as an external trigger
Defines the distance in dB to the trigger level that the trigger source must exceed
before a trigger event occurs. Setting a hysteresis avoids unwanted trigger events
caused by noise oscillation around the trigger level.
