a single point of trace data based on the detector
mode. The interval during which data for that
trace point is being collected is referred to as the
“bucket”. Thus, a trace is more than a series of
single points. It is actually a series of trace
“buckets”. The data may be sampled many times
within each bucket.
With the detector set to Auto, pressing [TRACE] >
{More (1 of 2)} > {Average} > {On} changes the detector.
The Auto choice that is made by the analyzer will
depend on the marker, trace, and trace averaging
functions chosen. If a marker function or
measurement is running, the Auto choice of the
detector is either Average or Sample. When a
detector (such as Average) is manually selected
instead of using the Auto function, that detector is
used without regard to other analyzer settings.
• Auto
Key access: [TRACE] > {More (1 of 2)} > {Detector} >
{Auto}
Selects the peak detector as the default. If a
measurement condition arises where a different
detector type is better, the system will use that
alternate selection.
•Normal
Selects the maximum and minimum video signal
values alternately. When selecting the normal
detector, “N” appears in the upper-left corner.
Key access: [TRACE] > {More (1 of 2)} > {Detector} >
{Normal}
•Average
Measures the average value of the amplitude
across each trace interval (bucket). When Average is
selected, “A” appears on the upper- left corner.
