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;
Δt = point- to- point time difference;
y = channel 1, 2, or REFA,REFB
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.
