When this key is selected, pressing the Peak Search key or issuing the equivalent SCPI command
finds the maximum point on the trace, but subject to the Excursion and Threshold set under the
Next Peak Criteria menu. The search is, of course, also subject to the peak-search qualifications.
This also affects the Peak Search half of Pk-Pk search and the Continuous Peak Search.

“Next Peak” Criteria
This key opens up a menu which allows you to independently set the Peak Excursion and Peak
Threshold and turn them on and off.

Backwards Compatibility
Notes In the X-Series, you can enable Pk Excursion and Pk Threshold independently, but they default
to “both on”. Since “both on” is always the case in ESA and PSA, this difference should not
cause code compatibility problems.
Initial S/W Revision Prior to A.02.00
Pk Excursion
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.
