DDR4 Functional/Protocol Debug and Analysis Reference Solution

Solution Brochure

When DDR4 memory systems don’t behave as expected, Keysight’s DDR4 functional/protocol debug and analysis solution provides trace capture and analysis, enabling the insight needed to understand system behavior and get to the root cause of system issues.

Next-Generation DDR4 Test Challenges

System and memory designers implementing DDR4 are striving for innovations in performance, density and power efficiency in their systems. Reliable measurements and analysis enable market-changing innovations and rapid fault isolation by providing insight into actual system behavior.

Using Keysight’s DDR4 functional/protocol debug and analysis solution to address DDR4 test challenges

Keysight’s DDR4 functional/protocol debug and analysis reference solution is the industry’s only functional/protocol validation, debug, analysis and bus level signal integrity insight solution covering address/command and data for DDR4 systems operating at data rates up to and including 4000 Mb/s.

U4164A logic analyzer module

The U4164A logic analyzer system combines reliable data capture with powerful analysis and validation tools to enable you to quickly and confidently validate and debug high-speed digital designs operating at speeds up to 4 Gb/s. The U4164A logic analyzer module delivers unique capabilities that enable you to make measurements and achieve levels of insight not available with other logic analyzers.

M9502/05A AXIe 2-5 slot chassis

The M9502/05A AXIe chassis is fully compatible with the AXIe 1.0 specification. It includes an embedded system module (ESM) that does not take up an instrument slot. This system module performs the chassis management functions contained in the AXIe specification. Additionally, it provides PCI and LAN interfaces for connection to an external computer, external clock and trigger connectors, and Keysight-exclusive, inter-chassis synchronization connectors. The local bus implemented in the M9502/05A provides the maximum 62 pairs allowed by the AXIe specification. Combine the M9502/05A with the M9048A PCIe desktop adaptor to achieve the highest system bandwidth.

M9536A AXIe embedded controller

The Keysight M9536A is the first AXIe embedded controller available on the market. It provides a high-performance PCIe Gen2 link to the AXIe backplane and is a powerful one-slot computer that can be used to build compact AXIe systems. It easily integrates into hybrid test systems using GP-IB, USB, and LAN due to the built-in front panel interfaces.

Hardware – Probing

DDR4 DIMM and SODIMM interposers are available through Keysight.

Contact your Keysight representative to order the interposer for your system under test. 

FS2510AB DDR4 DIMM and FS2512 DDR4 SODIMM interposers offer:
