05 | Keysight | 16860A Series Portable Logic Analyzers - Data Sheet
Debug, Verify, and Optimize DDR, LPDDR, and ONFi Memory Systems
The 16860A Series logic analyzers, in conjunction with memory specific probing solutions and
B4661A Memory Analysis Software, provide a cost-effective platform for debugging, verifying
and optimizing memory designs operating at ≤ 1400 MT/s. You can get a comprehensive view
into your system’s memory operation with bus decode, transaction overview, compliance
testing and performance analysis.
The 16860A Series supports Add/Cmd/Data state mode measurements for the following DDR
and LPDDR memory families. For higher speed or channel count DDR/2/3, LPDDR/2/3, DDR4
and LPDDR4 memory applications, refer to Keysight’s U4164A logic analyzer module which is
designed specifically for high-speed memory applications.

In addition, the 2.5 GHz timing mode provides a 3:1 ratio of sample rate to data rate so you can
perform timing measurements on DDR/LPDDR devices with < 400 MHz clock rate/
< 800 Mb/s data rate. When a 16862A or 16864A logic analyzer is configured with the 10 GHz
quarter channel timing option, the analyzer is capable of capturing Open NAND Flash Interface
(ONFi) traffic. Analysis of captured ONFi traffic is provided through the Performance Analysis
option (4FP/4NP/4TP) of the B4661A Memory Analysis Software.
