Source / Measure Units
High Accuracy. High Resolution. High Performance.

Keysight provides a wide range of source measure units (SMU) from precision, application-specific, general-purpose, to basic instruments. Keysight SMUs precisely force and simultaneously measure voltage and/or current.
Flexible Solution for Faster Workflows
Remove organizational test challenges with the PZ2100 high-channel density precision SMU solution. Meet all your evolving test system requirements with the 5 available SMU module options flexibly configurable and upgradable in the 1U, 4-slot mainframe. Address your application-specific needs with any module combination ranging from high-speed, high-resolution, and high-density SMUs. This flexibility reduces your system bring-up time while removing the need for multiple capital investments for every new project.
Learning Courses on All Things SMUs
Learn how the new PZ2100 SMU solution helps you overcome key challenges in application-specific tests, including low-power integrated circuits test, low-current LED test, VCSEL sensor and module test, narrow-pulsed LIV test, DC bias sourcing tests for optical receivers and modulators, datacenter applications, and more.
