2.4.3 Diode Characterization
With the Model 224 it is possible to obtain the necessary data
volts function, allows the measurement to be made accurate-
to plot I-V current-voltage characteristics of a diode over
ly. Figure 2-13 shows several examples of diodes whose
several decades. Figure 2-12 shows the configuration to be
