Next Peak Criteria

This key opens a menu that allows you to independently set the Peak Excursion and Peak Threshold and
turn them on and off.

Pk Excursion On/Off
Turns the peak excursion requirement on/off and sets the excursion value. The value defines the minimum
amplitude variation (rise and fall) required for a signal to be identified as peak. For example, if a value of
6 dB is selected, peak search functions like the marker Next Pk Right function move only to peaks that rise
and fall 6 dB or more.
When both Pk Excursion and Pk Threshold are on, a signal must rise above the Pk Threshold value by at
least the Peak Excursion value and then fall back from its local maximum by at least the Peak Excursion
value to be considered a peak.
Note that in the event that a sequence of trace points with precisely the same values represents the
maximum, the leftmost point is found.

Whenever you adjust the value of Pk Excursion (with the knob, step keys, or by completing a numeric
entry), and Peak Threshold is turned ON, the Peak Threshold Line and the Peak Excursion Region are
displayed. See Section "Pk Threshold Line On/Off" on page
