When discussing detectors, it is important to understand the concept of
a trace "bucket." For every trace point displayed, there is a finite time
during which the data for that point is collected. The analyzer has the
ability to look at all of the data collected during that time and present a
single point of trace data based on the detector mode. We call the
interval during which the data for that trace point is being collected,
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.
