Base level Base Low level of the displayed waveform -
the lower maximum of the sample distri-
bution. The measurement requires at
least one complete period of the signal.

Top level Top High level of the displayed waveform -
the upper maximum of the sample distri-
bution. The measurement requires at
least one complete period of the signal.
Top

Overshoot Over
in %
Overshoot of a square wave after a ris-
ing or falling edge. It is calculated from
measurement values top level, base
level, local maximum, local minimum,
and amplitude.
