Overshoot and Preshoot Measurements
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.
