Channel Power Measurement
Trace/Detector
• Auto- the detector selected depends on marker functions, trace functions, average type, and the trace
averaging function.
• Normal-the detector determines the peak of the CW-like signals, and it yields alternating maximums
and minimums of noise-like signals. This is also referred to as Rosenfell detection.
• Average-the detector determines the average of the signal within the sweep points. The averaging
method depends upon the Average Type selection (voltage, power or log scales).
• Peak-the detector determines the maximum of the signal within the sweep points.
• Sample-the detector indicates the instantaneous level of the signal at the center of the sweep points
represented by each display point.
• Negative Peak-the detector determines the minimum of the signal within the sweep points.

Notes: When you manually select a detector (instead of selecting Auto), that detector
is used regardless of other analyzer settings.
The Normal detector determines the peak of CW-like signals, and it yields
alternating maximums and minimums of noise-like signals. This method of
detection is also referred to as Rosenfell detection.
The Average detector determines the average of the signal within the sweep
points. The averaging method is Power Average (RMS).
The Peak detector determines the maximum of the signal within the sweep
points.
The Sample detector indicates the instantaneous level of the signal at the
center of the sweep points represented by each display point.
The Negative Peak detector determines the minimum of the signal within the
sweep points.
