You can calculate the global Maximum
and add the FPScript formula into the 2D-diagram as new curve. Activate the symbols for this curve. Now you see directly the global maximum of your signal in the diagram.
With the cursor you can go to the next or previous extremum. You can use the commands To Previous Peak Value and To Next Peak Value to move the cursor from peak value to peak value. On the Cursors tab in the Properties dialog box of a worksheet or document, you can specify whether local maxima, local minima or both are to be addressed. Here you can also enter a hysteresis, which determines what should or should not be recognized as an extremum. If some are skipped when navigating the extrema, you need to decrease the hysteresis. If small waves or noise in the course of the signal are recognized as extrema, then you need to increase the hysteresis.
