SOURCE MEASURE UNITS

A Source Measurement Unit (SMU) is a flexible test instrument which is capable of both sourcing and measuring voltage and/or current at the same time. A SMU is made up of a constant current source, a constant voltage source, a voltmeter, and an ammeter. It allows seven modes of operation: voltage generation/current measurement (VS/IM), voltage generation/voltage measurement (VS/VM), current generation/voltage measurement (IS/VM), current generation/current measurement (IS/IM), and voltage generation (VS), current generation (IS), and resistance measurement (VS/IM or IS/VM).

SMUs are commonly used for characterization of semiconductor devices, electronic components and devices. Yokogawa offers single, dual, and low voltage/current SMUs to accommodate a wide variety of applications, and feature the fastest testing speeds in the industry.

The GS610 is a highly accurate and highly functional programmable voltage/current source that incorporates voltage/current generation and measurement functions. The maximum output voltage and current are 110 V and 3.2 A, respectively. Evaluation of over a wide range of basic electrical characteristics is possible, because the GS610 can operate as a current source or a current sink.

The GS820 is equipped with two analog channels with each channel consisting of a constant voltage source VS, a constant current source IS, a voltmeter VM, and an ammeter IM. The two source measure channels are isolated.

The GS200 is a low voltage/current DC source with high accuracy, high stability, and high resolution. With its excellent traceability, stability, and 5 1/2-digit resolution, the GS200 generates extremely low-noise DC voltage and current signals that are required for many applications. Additionally, the optional monitoring feature turns the GS200 into a voltage and current measuring instrument.
