Peak Search
The Peak Search menu page allows you to define a specific threshold to determine which
signals can be considered peaks, excluding the unwanted signals from the search. A peak
can only qualify as a peak if there is a rising slope before the point and falling slope after
the point. A minimum can only qualify as a minimum if there is a falling slope before the
point and rising slope after the point.
