settings in the measurement configuration dialogs. For single measurement results, the
R&S CMW 500 often displays a table with all statistics types.
The statistics type is often combined with detector settings; see below.
3.2.4.2 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.
Minimum: The displayed result represents the minimum value in a specified
measurement interval.
Maximum: The displayed result represents the maximum value in a specified
measurement interval.
Detector Type
The measurement interval varies from one measurement to another; it is typically a
particular time or frequency interval.
Detector and statistics type settings can be combined. E.g. in the GPRF Power
measurement, the following results are available:
Statistics type: Current, Detector: RMS: The current trace, calculated from
RMS-averaged values over the specified "Measurement 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".
3.2.4.3 Peak Values
"Peak" values are calculated as the maximum of the magnitude times the sign:
For positive quantities such as the EVM, the peak value is equal to the maximum.
