Setting the Reference Level from the Measurement (Meas->Ref)
Sets the currently measured power as a reference value for the relative display. The
reference value can also be set manually via the Reference Value setting.

Defines the reference value for relative measurements in the unit dBm.

on page 896Use Ref Lev 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 397). If deactivated,
takes no offset into account.

on page 900Average 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.

on page 899Duty 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.

on page 897Using 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 FSW.
This setting is only available in conjunction with a compatible power sensor.
