Measurement definitions
Preshoot
Preshoot is distortion that precedes a major edge transition expressed as a
percentage of Amplitude. The X cursors show which edge is being measured
(edge closest to the trigger reference point).
Digital channel time measurements
Automatic measurements Preshoot and Overshoot are not valid measurements for
the math FFT function or for digital channels on the mixed-signal oscilloscope.
