All SMU Tutorials

The Source Measure Unit (SMU) is an instrument that can precisely source voltage or current and simultaneously measure voltage and/or current. It combines the useful features of a digital multimeter (DMM), power supply, true current source, electronic load and pulse generator, all into a single, tightly synchronized instrument in a compact form factor. SMUs are considered more useful than the combination of any of the five instruments, due to the measuring instrument’s versatility and high accuracy performance.

Keithley, the leader in SMUs, offers the broadest choice of SMU instruments available. Our SMUs, also known as SourceMeter® instruments, are fully programmable while delivering higher precision, resolution, and flexibility. Keithley SMUs are categorized into six areas: Graphical, Basic, System, High Power, High Density, and Optical.
