What is a Source Measure Unit (SMU)?
The Source Measure Unit (SMU) is a highly accurate and versatile instrument combining 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 for simultaneously sourcing and measuring voltage and current in a compact form factor.

Solution Brief
Simplifying DC-DC Converter Characterization
DC-DC converters are widely used electronic components that convert DC power from one voltage level to another while regulating the output voltage. This solution brief explains how to simplify DC-DC converter testing using a Keithley two-channel Series 2600B System SourceMeter SMU Instrument and a Tektronix Oscilloscope.
Application Note
Breakdown and Leakage Current Measurements on High Voltage Semiconductor Devices
Keithley has long had a strong presence in high power semiconductor device test. Most recently, Keithley introduced the 2470 1.1 kV Graphical SourceMeter® Source Measure Unit to address challenging measurements for SiC and GaN device testing. This application note considers the application of this new source measure unit with Keithley’s KickStart software for high voltage semiconductor.
