Agilent/Keysight U4970A

The Agilent/Keysight U4970A is a DDR5 Protocol Debug and Analysis Solution that delivers protocol debugging, compliance validation, and in-depth memory interface analysis across DDR through DDR5 generations. The system integrates a U4164A logic analyzer module, M9502A AXIe 2-slot chassis, M9537A embedded controller running Windows 10, and B4661A memory analysis software into a cohesive platform for high-speed memory characterization.
