9.3.2 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:
𝐼
𝑛

+Δ𝑡 +
𝑛
∑

Where:
• I = integrated waveform
• Δt = point- to- point time dierence
• y = channel 1, 2, 3, or 4 data points
• co = arbitrary constant
• i = data point index
The integrate operator provides an Oset softkey that lets you enter a DC oset correction factor for the input signal.
Small DC oset in the integrate function input (or even small oscilloscope calibration errors) can cause the integrate
function output to "ramp" up or down. This DC oset correction lets you level the integrate waveform.

9.3.3 Square Root
Square root (
√
) calculates the square root of the selected source. Where the transform is undened for a particular
input, holes (zero values) appear in the function output.
