5 Math Waveforms
Where:
• d = differential waveform.
• y = channel 1, 2, 3, 4, or Math 1, Math 2, Math 3 (lower math function) data
points.
• i = data point index.
•
∆t = point-to-point time difference.

Exponential
The Exponential (e^x) function performs a transform of the input source.

Integrate
dt (integrate) calculates the integral of the selected source. It shows the
accumulated amount of change.
