10 Spectrum Emission Mask Measurement
Trace/Detector
•
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.

Chan Detector Auto
Sets the detector to the default detection mode for the reference channel. This mode is dependent upon
the current reference channel conditions.
