Specifies the detection mode. For each trace interval (bucket), average
detection displays the average of all the samples within the interval.
• Negative peak detection displays the lowest sample taken during the
interval being displayed.
• Positive peak detection displays the highest sample taken during the
interval being displayed.
• Sample detection displays the sample taken during the interval being
displayed, and is used primarily to display noise or noise-like signals.
In sample mode, the instantaneous signal value at the present display
point is placed into memory. This detection should not be used to
make the most accurate amplitude measurement of non noise-like
signals.
• Average detection is used when measuring the average value of the
amplitude across each trace interval (bucket). The averaging method
used by the average detector is set to either video or power as
appropriate when the average type is auto coupled.
• Normal detection selects the maximum and minimum video signal
values alternately. When selecting Normal detection, “Norm”
appears in the upper-left corner.
