The Keysight U4002A is a 2-slot AXIe chassis that serves as a modular, scalable platform for high-density test and measurement systems. This half-width instrument accommodates application-specific blades alongside an integrated chassis manager, enabling portable deployments or lab installations with optional rackmount brackets. The architecture supports system expansion through multi-chassis networking and centralized control, making it ideal for complex testing workflows that demand high-performance instrumentation.
