Preshoot; Average - Agilent Technologies InfiniiVision 3000 X-Series User Manual

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).
Rising edge preshοot =
Falling edge preshοot = Base − D local Minimum

Average

Average is the sum of the levels of the waveform samples divided by the
number of samples.
Where x
measurement interval.
The Full Screen measurement interval variation measures the value on all
displayed data points.
The N Cycles measurement interval variation measures the value on an
integral number of periods of the displayed signal. If less than three edges
are present, the measurement shows "No edges".
The X cursors show what interval of the waveform is being measured.
