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~ number of samples 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.
17.3.2 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 "ramp" up or down, as shown below:
Integral without Offset
Integral with Offset
In addition, the integral operation can be performed within a specified gate. Click Gate area in the
math dialog box, and enable the Gate function, then set Gate A and Gate B to define the gate.
The setting of the gate cursors is similar to that of normal cursors. See "Select and Move Cursors" for
details.
