Softkey presents a submenu to select a specific detector
type, or allows the analyzer to select the appropriate
detector (select Auto) for a particular measurement.
Regarding detectors, it is important to understand what is a
trace “bucket”. For every trace point displayed, there is a
finite time during which the data for that point is collected.
The analyzer looks at all of the data collected during that
time and present a single point of trace data based on the
detector mode. The interval during which the data for that
trace point is being collected, is called 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.
