Integrate
∫
dt (integrate) calculates the integral of the selected source.
You can use integrate to calculate the energy of a pulse in
volt-seconds or measure the area under a waveform.
∫
dt plots the integral of the source using the “Trapezoidal
Rule”. The equation is:
Where
I = integrated waveform
∆
t = point-to-point time difference
y = channel 1, 2, or function 1 + 2, 1 – 2, and 1 * 2 data

In Delayed sweep horizontal mode, the
∫
dt function does not
display in the delayed portion of the display.

dt. The source can be
any analog channel, or math functions 1 + 2, 1 – 2,
and 1 * 2.
• Scale
— lets you set your own vertical scale factors for
∫
dt expressed in unit-seconds/division, where units can
be V (Volts), A (Amps), or W (Watts). Units are set in
