Rapidly Expanding Array of Test Applications Continues to Drive Source Measurement Unit Instrument Technology

SMUs are fast-response, read-back voltage and current sources with high accuracy measurement capabilities, all tightly integrated in a single enclosure. They are designed for circuit and device evaluation where a DC signal must be applied to a device under test (DUT) and the response to that signal measured. They are capable of four-quadrant operation, acting as a positive or negative DC source or as a sink (load). They also provide highly repeatable measurements. This white paper outlines why instrument-based SMUs, used either alone or integrated with other SMUs in a system, typically provide the fastest, most accurate, most flexible solutions for the widest range of demanding applications. ■
