c To fine-tune the location of the second cursor to 4
volts on the x-axis, drag the crosshairs until the
x-axis value of the A2 cursor in the cursor window
is approximately 4.0. You can also press V+r
and V+l for tighter control.
Figure 13 shows the Probe window with both cursors
placed.
Figure 13 Voltage difference at V(In) = 4 volts.
To delete all of the traces
1 From the Trace menu, choose Delete All Traces.
At this point, the design has been saved. If needed,
you can quit Capture and PSpice and complete the
remaining analysis exercises later using the saved
design.
