The Trace menu shows that two Detector controls are available, one for
the Reference Channel (default Auto is Average to facilitate the Power
Integration), and another for all the Offset segments (default Auto is PEAK,
to facilitate finding PEAK signal energy when comparing against Limits).
There is only 1 Trace available, and like the other Channel Measurements,
it is set to average.
