Source measure unit
The Source–measurement unit (SMU) is a type of test equipment which, as the name indicates, is capable of both sourcing and measuring at the same time.
Overview
The source-measurement unit, or source measure unit (SMU) as it is more commonly called, is an electronic instrument that is capable of both sourcing and measuring at the same time. It can precisely force voltage or current and simultaneously measure precise voltage and/or current.
SMUs are used for test applications requiring high accuracy, high resolution and measurement flexibility. Such applications include I-V characterizing and testing semiconductors and other non-linear devices and materials, where sourcing voltage and current source span across both positive and negative values.To accomplish this, SMUs have four-quadrant outputs.[1] For characterization purposes SMUs are bench instruments similar to a curve tracer. They are also commonly used in automatic test equipment and usually are equipped with an interface such as GPIB or USB to enable connection to a computer.
