8.5 Integrate
(integrate) calculates the integral of the selected source. It shows the accumulated amount of
∫ ����
change.
Use integrate to calculate the energy of a pulse in volt-seconds or measure the area under a waveform
by measuring the difference in the integrate function value across the pulse or waveform.
plots the integral of the source using the "Trapezoidal Rule". The equation is:
∫ ����
Where:
•
= integrated waveform
��
•
= point- to- point time difference
��
•
= channel 1, 2, 3, or 4 data points
��
•
= arbitrary constant
��
��
•
= 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.
8.6 Square Root
√
Square root (
) calculates the square root of the selected soruce.
Where the transform is undefined for a particular input, holes (zero values) appear in the function output.
