Source and Measure with a Single Unit
SMUs bring precision sourcing and measurement together in a single, unified instrument. Designed for modern semiconductor and electronic component testing, they deliver stable voltage and current output while capturing high-resolution measurement data in real time. This tight integration reveals device characteristics that traditional bench setups often miss, enabling faster, more confident design decisions.
With wide dynamic ranges, low noise, and smooth transitions between operating modes, SMUs support everything from simple biasing to advanced I-V sweeps and pulse testing. Engineers rely on them to characterize diodes, transistors, sensors, and silicon photonics with accuracy and repeatability.
By consolidating multiple instruments into one, SMUs simplify test setups, reduce measurement uncertainty, and streamline workflows in R&D, design validation, and production test.
