Agilent/Keysight W2631B

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.

Technical Specifications

• DDR2 x16 DRAM signal probing with support for 92-ball BGA packages (all signals) and 84-ball packages (without mechanical support balls)


• DDR2 data rates up to 667 MT/s with 16950B logic analyzer


• Compatible with all DDR2 speeds using 16962A logic analyzer


• Data capture capability up to 4 Gb/s with U4154A AXIe-based logic analyzer systems


• Non-intrusive connection maintains signal integrity during measurement

Key Features

• Zero Insertion Force (ZIF) probe integration - compatible with E5384A or E5826A probes


• DDR2/DDR3 eye finder and eye scan functionality for signal integrity analysis
