A Source Measurement Unit (SMU) is an instrument that incorporates both a sourcing and a measuring function, sourcing and measuring current or voltage simultaneously. The Source Measurement Unit combines the ability to be a power supply or generator with the functions of a digital multimeter. We offer a large range of Source Measurement Units from market-leading manufacturers such as Keithley, Keysight, Aim-TTi, and Rohde & Schwarz. These highly accurate devices are ideal for even the most challenging applications, such as lab or test situations. Most consumer products will have been tested by these machines prior to market launch.
