20.3.1 Differential
The differential (d/dt) operator is used to calculate the derivative of the selected
source. It is always used to measure the instantaneous slope of the waveform,
such as the slew rate of an operational amplifier.
The differential equation is:
dx
y(i) - dx)+(iy
di
Where:
d = Differential result
y = Values of source data
i = Data point index
dx = Differential interval
The range of “dx” in the d/dt menu is 4~256 pts.
Note: Differentiation is sensitive to noise. It is helpful to set the acquisition mode
to “Average” or “ERES” to help minimize the visible effects of additional noise.
20.3.2 Integral
Integral operation integrates the waveforms on the screen or within the
specified gate.
Setting Offset in the integral menu provides an approach to correct the DC
offset of the source. Small DC offsets in the input signal (or even small offset
errors of the oscilloscope itself) may cause the integral output waveform to
