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.
