The source measure unit (SMU) 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 voltage and/or current.
An SMU instrument can source and sink power in all four quadrants.
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.
