mode to Average.
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.
Figure 79 Difference Function Operation
You can use differentiate to measure the instantaneous slope of a waveform. For example,
the slew rate of an operational amplifier may be measured using the differentiate function
