Peak Search
In the event that a sequence of trace points with precisely the same values represents the maximum, the
leftmost point is found.

More Information
If two signals are very close together and the peak excursion and threshold criteria are met at the
outside edges of the combined signals, this function finds the highest of these two signals as a
peak (or next peak). However, if a signal appears near the edge of the screen such that the full
extent of either the rising or falling edge cannot be determined, and the portion that is on screen
does not meet the excursion criteria, then the signal cannot be identified as a peak.
When measuring signals near the noise floor, you can reduce the excursion value even further to
make these signals recognizable. To prevent the marker from identifying noise as signals, reduce
the noise floor variations to a value less than the peak-excursion value by reducing the video
bandwidth or by using trace averaging.
