Combining a precision current and voltage source with a high resolution digital multimeter, source measure units are precision DC instruments that can operate in all four quadrants to allow it to be used as a generator and load. As such, they have seen use in many applications where they are operated as a battery, a stimulus for transistors, a power supply, and as a test device for verifying analog to digital converters.

Yokogawa's instruments go beyond conventional options. They are highly accurate, highly functional with programmable voltage/current source that incorporates voltage/current generation for a broader application.
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.
