SMUs are and have been useful tools in power engineering since they were first developed in the early 1980s for semiconductor characterization. The growth in utility and functionality of these products also are a testament to the extent semiconductor-based solutions have permeated the marketplace. SMUs address high-accuracy and -resolution applications beyond characterizing and testing semiconductors, testing other nonlinear devices and materials in which voltage and current embrace both positive and negative values. The Source/Measure Unit TechXchange provides informative and interesting material on this critical topic in power test.
