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 on page 798
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 on page 797
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.
Remote command:
[SENSe:]PMETer<p>:DCYCle[:STATe] on page 795
[SENSe:]PMETer<p>:DCYCle:VALue on page 795
7.3.2.3 How to Work With a Power Sensor
The following step-by-step instructions demonstrate how to set up a power sensor. For
details on individual functions and settings see Chapter 7.3.2.2, "Power Sensor Set-
tings", on page 278.
The remote commands required to perform these tasks are described in Chap-
ter 11.8.5.2, "Working with Power Sensors", on page 791.
How to Set Up a Power Sensor
Up to 4 external power sensors can be configured separately and used for precise
power measurement. All power sensors can be activated and deactivated individually.
The following procedure describes in detail how to configure and activate power sen-
sors.
1. To display the "Power Sensor" tab of the "Input" dialog box, do one of the following:
● Select "Input" from the "Overview".
● Select the [INPUT/OUTPUT] key and then the "Power Sensor Config" softkey.
