Differentiate
d/dt
(differentiate) calculates the discrete time derivative of the selected source.
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
Averaging
(see
"Selecting the Acquisition Mode"
d/dt
plots the derivative of the selected source using the "average slope estimate
at 4 points" formula. The equation is:
Where:
• d = differential waveform.
• y = channel 1, 2, 3, or 4, or g(t) (internal arithmetic operation) data points.
• i = data point index.
•
Δ
t = point-to-point time difference.
