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
∆
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 t is the ten point’s point- to- point time
difference.
Figure 44 Differential 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
