13. Overshoot: Overshoot is distortion that follows a major edge transition expressed as a percentage of Amplitude. ROV
means rising edge overshoot and FOV means falling edge overshoot.

14. 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).
