The common emitter NPN BJT Ic-Vce characteristics is a plot of the collector current, Ic, (linear scale) vs. the collector-emitter voltage, Vce, (linear scale) with the base current, Ib, as a parameter for positive Vce . Do this for 0 <= Ib <= 100 µA and 0 <= Vce <= 4 V . The measurement configuration is shown in the above figure. The collector-emitter voltage, Vce, are swept from 0 to a positive voltage while Ic and Ib are measured. Users can use AIM-Spice to fit the experimental data and extract device parameters.

The experimental parameters to be entered in the Source Setup pop-up panel include the start, stop, and number of steps for the sweep. You may also set the current compliance for protection. The collector-emitter voltage, Vce, should not be set too high to reach the breakdown voltage.
