data evaluated during that time and present a
single point of trace data based on the detector
mode. We call the interval during which 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.
With the detector sets to Auto, Pressing [TRACE] >
{More (1 of 2)} > {Average} and select On changes the
detector. The Auto choice depends on marker, and
trace functions, and the trace averaging function. If
a marker function or measurement is running, the
Auto choice of detector is either Average or
Sample. When one of the detectors (such as
Average) is manually selected instead of Auto, that
detector is used without regard to other analyzer
settings.
• Auto
Selects peak detector as the default. If a
measurement condition arises where a different
type of detector scheme would be better utilized,
the system will use the alternate scheme.
Key access: [TRACE] > {More (1 of 2)} > {Detector}
•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}
•Average
Measures the average value of the amplitude
across each trace interval (bucket). When Average is
selected, “A” appears on the left corner.
Key access: [TRACE] > {More (1 of 2)} > {Detector}
