Memory System Validation
Keysight Technologies has the measurement tools you need to validate the very latest
memory technologies. These include logic analyzers, oscilloscopes and software for
automated compliance, decode, and protocol checking.
To complement our high speed digital instruments and software, Keysight offers probing
solutions with a comprehensive range of Ball Grid Array (BGA) interposers. When posi-
tioned between the processor memory controller and the memory device, the interposers
allow you to make signal quality or protocol measurements with minimal effect on the
system-under-test.
Memory technology is constantly advancing in speed and density, and you need probing
solutions that keep up with these developments. Keysight Technologies is at the forefront
of the latest memory standards, chip technologies, and measurement techniques. Your
Keysight Applications Engineer and Keysight’s Interposer Design Team can assist you with
selecting the best BGA interposer and probing technique for your application.
You can choose from a large selection of existing interposer designs, or define probing
solutions customized to your specific needs. Keysight’s standard interposers are available
for several JEDEC standard packages with a variety of ball counts. The selection guide in
this catalog gives you an overview of the interposers available and provides links to the
corresponding data sheets. For additional DRAM packages or to meet different mechanical
requirements, Keysight’s proven development process can produce custom BGA interposer
designs of the highest quality.
Browse the catalog and then contact your local Keysight Applications Engineer for advice
on the right products and measurement techniques to ensure the successful validation of
your memory system.
