data controlled 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.
When the detector sets to
Auto, Pressing [TRACE] >
{More (1 of 2)} > {Average} and select On changes the
detector. The Auto choice depends on marker
functions, 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 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}
• Pos Peak
Obtains the maximum video signal between the last
display point and the present display point and
stores this value in memory. It’s used primarily
