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:
Where:
I = integrated waveform
Δt = point-to-point time difference
y = Channel or Math data points
c
o
= arbitrary constant
i = data point index
The Offset softkey lets you enter a DC offset correction for the input signal.
A small DC offset in the integrate function input or a small calibration error can cause the
integrate transform output to "ramp" as shown below. Use the Offset softkey to remove the
offset and prevent ramping.
