Description
Integration
(Total)
Calculates the di󰀨erence between the area (V·s) enclosed
by the zero position (0 V position) and the part of the
signal waveform where its amplitude is positive and the
area (V·s) enclosed by the zero position (0 V position)
and the part of the signal waveform where its amplitude is
negative.
Calculates the integration between the cursors when
performing the calculation over a specic range (selected
using the A/B cursors).
