Example: using cursors
Figure 97 shows both cursors on the V(1) waveform in the
analog area of the plot.
Cursor 1 is positioned on the first trough (dip) of the V(1)
waveform. Cursor 2 is positioned on the second peak of
the same waveform. In the Probe Cursor window, cursor
1 and cursor 2 coordinates are displayed (A1 and A2,
respectively) with their difference shown in the bottom
line (dif). The logic state of the Out signal is also displayed
to the right of the cursor coordinates.
