Algebra
The oscilloscope supports math function operation including differential (d/dt), integral (
∫
𝑑𝑡
) and square root (
√
).
13.3.1
Differentiate
d/dt
(differentiate) calculates the discrete time derivative of the selected source. Where:
•
d = differential waveform
•
y = values of source data
•
i = data point index
•
dx= differential interval
The range of
dx
in the d/dt menu is 4~256.
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.

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.
Because differentiation is very sensitive to noise, it is helpful to set acquisition mode to Average.
