Trace > Add Trace. . . from the menu bar but it’s easier to return to the Capture window, leaving

PSpice open. Turn off the V button if the original values are still displayed – they get in the

way. Choose the Voltage Probe tool (something like a magnifying glass with a V in it, or select

PSpice > Markers > Voltage Level from the menu bar) and click on the wire that joins the two

resistors as in ﬁgure 17. The probe will change colour. Return to PSpice and you will ﬁnd a

line whose colour matches that of the probe.

Make the PSpice window active again and you should see a line on the plot, as in ﬁgure 18

on the following page. This shows the voltage at the selected node as a function of V1.

There are many options to control the plot, selected from the menu or button bars. You can

also edit the simulation proﬁle and repeat the simulation from PSpice, which is convenient if

you ﬁnd that the range is wrong.

Cursors are useful if you want exact readings from a plot. Choose Trace > Cursor > Display

from the menu or click the button. This will generate two sets of cross-wires which can be
