Key Features & Specifications

DDR3/4, LPDDR2/3/4 and ONFi analysis (licensed option -4FP/4NP/4TP)

  • Rapidly navigate DDR3/4, LPDDR2/3/4, or ONFi traffic flow using “Transaction Decode” and “Traffic Overview” views
  • View performance calculations and graphs of MByte data rates, % bus utilization, graphic rolling refresh window, and address mapping for DDR3/4 or LPDDR2/3/4
  • Navigate quickly across multiple ONFi targets using the condensed ONFi analysis “Timeline” view
  • Save time by visualizing an ONFi operation as a set of logically associated commands in a sequence, using the “Details” view of the ONFi transactions

DDR and LPDDR compliance violation analysis tools

  • Test compliance violations across speed changes using the post-process compliance violation tool
  • Identify DDR/2/3/4 or LPDDR/2/3/4 state machine, protocol compliance, and protocol level bus cycle timing violations using either post-process or real-time tools
  • Save time with automated real-time DDR2/3/4 or LPDDR2/3/4 protocol compliance measurements and trace captures using the real-time compliance violation analysis tool
  • Edit parameters of the DDR/LPDDR standard preset tests easily using the enhanced parameter editing interface for both post-process and real-time tools

DDR decoder

  • Decodes DDR, DDR2, DDR3, DDR4 and MRS commands
  • Includes selection to decode MRS of DDR4 RDIMM and LRDIMM
  • Enables fast physical address trigger setup with physical address trigger tool

LPDDR decoder

  • Decodes LPDDR, LPDDR2, LPDDR3 and LPDDR4 commands and MRS commands
  • Includes selection to decode MRS of DDR4 RDIMM and LRDIMM
  • Enables fast physical address trigger setup with trigger tool for LPDDR/2/3


The Keysight B4661A memory analysis software offers a suite of tools that include the industry’s first protocol compliance violation testing capability across speed changes, a condensed traffic overview for rapid navigation to areas of interest in the logic analyzer trace, powerful performance analysis graphics, and DDR and LPDDR decoders. With the B4661A memory analysis software and a Keysight logic analyzer*, users can monitor DDR3/4 or LPDDR2/3/4 systems to debug, improve performance, and validate protocol compliance. Powerful traffic overviews, multiple viewing choices, and real-time compliance violation triggering help identify elusive DDR/LPDDR system violations.

The Keysight B4661A memory analysis software provides four standard software features and four licensed memory analysis options. Enhanced ONFi (open NAND flash interface) analysis has been added to the B4661A Memory analysis SW, licensed option -4NP/TP/FP, starting with version 6.40 SW release in June 2017.

Standard software features:

  • Default configurations for DDR and LPDDR probing solutions for Keysight logic analyzers*
  • DDR setup assistant
  • DDR eye finder / eye scan
  • DDR configuration creator

* B4661A is compatible with Keysight logic analyzers supported by Version 6.20 or higher of the logic and protocol analyzer software. ONFi analysis is 6.40 supported in version 6.40 and higher SW.
