Spectrum Emission Mask Measurement
Trace/Detector
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.
Offset Detector Accesses a menu of functions that enable you to control the detector for offsets. The following choices
are available.
• 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.
