8 Channel Power Measurement
Trace/Detector
•
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.

Couplings
When Detector setting is “Auto” ([:SENSe]:CHPower:DETector:AUTO?), Detector
([:SENSe]:CHPower:DETector[:FUNCtion]?) switches aligning with the switch of this parameter:
“NORMal” with Clear Write, “AVERage” with AVERage, “POSitive (peak)” with MAXHold, and
“NEGative (peak)” with MINHold.
