Agilent/Keysight U281B

The Agilent/Keysight U2814B is a modular instrument chassis that enables construction of custom test systems by housing up to six USB modular instruments in a single 4U platform. Built on the U2781A chassis, it delivers flexible, scalable testing for R&D, manufacturing, and field environments through hot-swappable modules, integrated power management, and synchronized multi-instrument operation.
