SDS5000X Series Digital Oscilloscope User Manual
y = Values of source data
i = Data point index
dx = Differential interval
The range of “dx” in the d/dt menu is 2~20. The measurement units are point
and the corresponding time difference range is 0.02~0.20 div. “div” indicates
the number of the pixel points that each division has and is 100 for the
SDS5000X. If dx = 10 points, the time difference is:
0.01*10 = 0.1 div
Then the differential operator calculates the "average slope in 10 points" of the
selected source and dx represents the time difference between the 10 sampled
points.
dx = 2
dx = 6
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.
19.3.2 Integral
Integral operation integrates the waveforms on the screen or within the
specified gate.
