Detector
Auto Man
Selects a specific detector, or allows to pick the appropriate
detector (through Auto) for a particular measurement.
When discussing 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 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.
