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.

Learning Center Learn Source Measure Units(SMU) basics - from fundamental measurement concepts to key industry applications, such as how to use an SMU in a 2 terminal and 3 terminal device obtaining IV curves and how an SMU can simplify the test setup and increase productivity. PRIMER Choosing the Optimal Source Measurement Unit Instrument for Your Test and Measurement Application In this comprehensive White Paper, you will learn more about the real benefits of SMU instruments for test and measurement applications and their ability to source and measure signals simultaneously. 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. APPLICATION NOTE Generating Clean 10 µs Pulses with the 2601B-PULSE System SourceMeter® Instrument Outputting high quality current pulses for characterizing VCSELs for LIDAR or other optoelectronic devices poses many challenges. Read this application note to learn how you can easily source current pulses as short as 10 μs and minimize device self heating.
