Agilent Technologies Inc. says it has developed the industry's first oscilloscope-based DDR3 compliance test application. This tool is suited for engineers working in the computer, data storage, electronic data processing and consumer electronics industries.

The U7231A DDR3 test application, which runs on Infiniium 54850 and 80000 Series oscilloscopes, provides DDR3 compliance measurements based on the JEDEC JESD79-3 DDR3 SDRAM specifications. It covers clock, electrical and timing parameters.

This application also features Advanced Debug mode, which provides critical measurements such as eye-diagram analysis, mask tests, ringing measurements and other tests that are not covered in the JEDEC specifications. Each of these tests helps engineers find the root causes of problems in their designs.

The Agilent U7231A DDR3 application automatically configures the oscilloscope for each test and generates an informative HTML report at the end of the test. It compares the results with the specification test limit and indicates how closely the device passes or fails each test. The complex analysis runs seamlessly within the scope, which saves users' time and effort compared to making and analyzing measurements manually.

When a problem is encountered during the test, engineers can use the Advanced Debug feature to analyze the cause. The application sets up the scope to separate read and write signals so engineers can debug signal integrity issues. Infiniium oscilloscopes also feature InfiniiScan, which is a powerful tool for finding signal problems.

The Agilent U7231A compliance test application is available now at a price of $3,000.
