Math Function Operation
The oscilloscope supports math function operation including differential (d/dt), integral (∫dt)
and square root ( ).
Differentiate
d/dt (differentiate) calculates the discrete time derivative of the selected source.
Where:
d = differential waveform.
y = channel 1, 2, 3, or 4 data points.
i = data point index
Δ t = point- to- point time difference.
The dx option under d/dt math function operation menu shows the point- to- point time
difference, and it ranges from 0.02div to 0.40div. “div” indicates the number of the pixel
points that each division has. The oscilloscope has 50 pixel points per division. Take
0.2div as an example: 0.2*50=10. It means to calculate the ten point’s discrete time
derivative of the selected source, and the Δ t is the ten point’s point- to- point time
difference.
