Keithley Source Measure Unit (SMU) is also known as Keithley SourceMeter®. It is an instrument that can precisely source voltage or current and simultaneously measure voltage and/or current. It integrates the capabilities of an individual power supply, a digital multimeter (DMM), a current source, and an electronic load into a single, tightly synchronized bench instrument.

Keithley offers the broadest choice of SMU instruments available. All Keithley SourceMeter® instruments are fully programmable while delivering higher precision, resolution, and flexibility ideal for materials research, semiconductor devices (transistor, BJT, diode, power MOSFET, power semi, LED), electronic circuits and more.
