The Agilent/Keysight W2631B is a DDR2 x16 BGA probe set engineered for non-intrusive signal access to command, address, and data buses in DDR2 DRAM devices. Designed for integration with 16900 Series logic analyzers and oscilloscope systems, it enables precision signal acquisition and analysis without requiring board redesign. The probe provides full electrical and mechanical isolation while maintaining signal integrity across DDR2 memory validation workflows.
