Delay

Delay is defined as the difference between the selected edge on source 1
and the selected edge on source 2, closest trigger reference point being the
middle threshold points on the waveforms. Negative delay indicates that
the selected edge of source 1 occur after the selected edge of source 2.

Preshoot and Overshoot

Preshoot

Preshoot is the distortion that precedes a major edge transition expressed
as a percentage of amplitude (refer to Figure 3- 26).
