Remote command:
CALCulate<n>:PMETer<p>:RELative[:MAGNitude]:AUTO ONCE on page 729
Reference Value
Defines the reference value for relative measurements in the unit dBm.
Remote command:
CALCulate<n>:PMETer<p>:RELative[:MAGNitude] on page 729
Use Ref Level Offset
If activated, takes the reference level offset set for the analyzer (Ref Level Offset soft-
key) into account for the measured power.
Remote command:
[SENSe:]PMETer<p>:ROFFset[:STATe] on page 838
Number of Readings
Defines the number of readings (averagings) 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 averaging and sweep count
of the "Trace" menu are independent from this setting.
Results become more stable with extended averaging, 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 837
External Power Trigger
Activates the creation of a trigger signal in the power sensor.
For details see Figure 3-47.
