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.

Rising edge preshoot = Base - D local Minimum
