Agilent/Keysight E5847A

The Keysight E5847A is a single-ended ZIF probe that connects to the W3633A DDR3 DRAM BGA probe for direct access to data traffic on industry-standard DDR3 DIMMs. It integrates with Keysight 16000 Series and U4154A logic analyzers via 90-pin cable connectors, enabling comprehensive signal capture and analysis at the memory interface.

Technical Specifications

• 46 total channels: 44 single-ended data channels and 2 differential clock channels


• Maximum data rate: 1333 Mb/s


• Equivalent load capacitance: 1.5 pF


• Minimum measurable signal amplitude: 250 mV p-p

Key Features

• Low-profile load capacitance minimizes signal distortion and maintains signal integrity on target DDR3 modules


• Direct connection to W3633A BGA interposer eliminates intermediate cabling complexity


• Single-ended and differential channel architecture supports both data and clock signal observation


• 90-pin connector interface ensures reliable mechanical and electrical mating with compatible logic analyzers

Typical Applications

• DDR3 DRAM bus characterization and validation


• Memory subsystem debugging during hardware development


• Signal integrity measurement on high-density BGA packages


• Post-silicon validation and failure analysis

Compatibility & Integration Works exclusively with the W3633A DDR3 DRAM BGA probe. Compatible logic analyzers include Keysight 16000 Series modules and the U4154A AXIe-based logic analyzer module. All connections use industry-standard 90-pin cable connectors for plug-and-play integration into existing test benches.
