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:
∑
=
∆+=
n
0i
i0n
ytcI
Where:
I = integrated waveform
Δt = point- to- point time difference
y = channel 1, 2, 3, or 4 data points
c
o
= arbitrary constant
i = data point index
The integrate operator provides an
Offset
softkey that lets you enter a DC offset correction
factor for the input signal. Small DC offset in the integrate function input (or even small
oscilloscope calibration errors) can cause the integrate function output to "ramp" up or
down. This DC offset correction lets you level the integrate waveform.
