10. To display the integral of a single pulse, configure a V-marker cursor whose source

is the first math waveform ("MA1" or "Integral") and position the cursors at the
beginning and at the end of the pulse.
The procedure is described in the previous example,

chapter 4.5, "Performing Cur-

sor Measurements"

The integral between the two cursors is displayed as "

Δ

V" in the result table.
