The statistics type is often combined with detector settings, see
4.3.4.2
Detectors
The detector setting specifies how a single measurement result is calculated from a set
of adjacent measurement points:
●
RMS:
The displayed result represents the RMS average (e.g. the mean power) in a
specified measurement interval. Over-estimation of stochastic signals (noise) is avoi-
ded.
●
Minimum:
The displayed result represents the minimum value in a specified mea-
surement interval. Narrow peaks cannot be smoothed out due to averaging.
●
Maximum:
The displayed result represents the maximum value in a specified mea-
surement interval.
Fig. 4-2: Detector Type
The measurement interval varies from one measurement to another; it is typically a par-
ticular time or frequency interval.
Detector and statistics type settings can be combined. E.g. in the GPRF Power mea-
surement, the following results are available:
●
Statistics type: Current, Detector: RMS:
The current trace, calculated from RMS-averaged values over the specified "Mea-
surement Length".
●
Statistics type: Current, Detector: Minimum:
The current trace, calculated from minimum values within the "Measurement Length".
●
Statistics type: Current, Detector: Maximum:
The current trace, calculated from maximum values within the "Measurement
Length".
●
Statistics type: Average, Detector: RMS:
The average trace, calculated from RMS-averaged values over the "Measurement
Length".
●
Statistics type: Minimum, Detector: Minimum:
The minimum trace, calculated from minimum values within the "Measurement
Length".
●
Statistics type: Maximum, Detector: Maximum:
The maximum trace, calculated from maximum values within the "Measurement
Length".
