To place cursors on V(In) and V(Mid)
1 From PSpice’s Trace menu, point to Cursor and
choose Display.
Two cursors appear for the first trace defined in the
legend below the x-axis—V(In) in this example. The
Probe Cursor window also appears.
2 To display the cursor crosshairs:
a Position the mouse anywhere inside the Probe
window.
b Click to display the crosshairs for the first cursor.
c Right-click to display the crosshairs for the second
cursor.
In the trace legend, the part for V(In) is outlined in the
crosshair pattern for each cursor, resulting in a dashed
line as shown in Figure 11.
3 Place the first cursor on the V(In) waveform:
a Click the portion of the V(In) trace in the proximity
of 4 volts on the x-axis. The cursor crosshair
appears, and the current X and Y values for the
first cursor appear in the cursor window.
b To fine-tune the cursor location to 4 volts on the
x-axis, drag the crosshairs until the x-axis value of
the A1 cursor in the cursor window is
approximately 4.0. You can also press r and l
for tighter control.
4 Place the second cursor on the V(Mid) waveform:
a Right-click the trace legend part (diamond) for
V(Mid) to associate the second cursor with the Mid
waveform. The crosshair pattern for the second
cursor outlines the V(Mid) trace part as shown in
Figure 12.
b Right-click the portion on the V(Mid) trace that is
in the proximity of 4 volts on the x-axis. The X and
Y values for the second cursor appear in the cursor
window along with the difference (dif) between
the two cursors’ X and Y values.
