Integrate
dt (integrate) calculates the integral (area under the curve) of the selected channel. 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:
l
I = integrated waveform
l
Δ t = point-to-point time difference
l
y = channel 1, 2, 3, or 4 data points
l
c
o
= arbitrary constant
l
i = data point index
The integrate operator provides an
Offset F key that lets you enter a DC offset correction factor for the
input signal. A small DC offset in the integrate function input (or even small oscilloscope calibration
errors) can cause the integral to "ramp" up or down. The DC offset correction lets you level the
integral waveform.
