3.1.7.3 Peak Search
The controls on this tab allow you to move the marker to selected peaks of the
signal, giving you enormous analysis capabilities, particularly when combined with
the Delta marker function.
When "Pk Excursion" on page 215 and "Pk Threshold" on page 214 are both OFF:
–
"Peak Search" on page 209, "Continuous Peak Search" on page 212, and
maximum part of "Pk-Pk Search" on page 211 search the trace for the point with
the highest y-axis value that does not violate the LO feedthrough rules. A rising
and falling slope are not required for these three peak search functions
–
The remaining search functions: "Next Peak" on page 210, "Next Pk Right" on
page 210, etc. only consider trace points that have a rising and falling slope on
the left and right respectively
NOTE
Pressing the Peak Search hardkey automatically moves you to the Peak
Search page of the Marker menu
and
performs a peak search.
Pressing the Peak Search tab once you are already
in
the Marker menu does
not
perform a peak search.
Marker Frequency
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Frequency" on page 204 on the Settings tab.
