Transcat offers source measure units in various categories, from precision to application specific. A source and measurement unit (SMU) is a device that supports testing applications, including those that demand high accuracy and high resolution capabilities. The units essentially combine the functionality of a DMM with a precise power supply, while also offering excellent low current operations. An SMU can precisely source voltage or current to a device under test or development, while simultaneously measuring voltage and/or current. These simultaneous capabilities often equate to faster testing processes. An SMU is the smart solution when low-level voltage, current, and resistance are needed for functional tests and electronics profiling. Unit applications range from design validation to manufacturing, and SMUs are frequently used within the semiconductor and electronics industries.
