USB 3.0 compliance test solution

21 January 2009 Test & Measurement

Agilent has developed a comprehensive solution for testing SuperSpeed USB 3.0 devices to ensure compliance with the newly published standards.

At the first USB 3.0 Developers Conference held recently in California, Agilent demonstrated its new USB 3.0 transmitter and receiver compliance test solutions. This demonstration included the industry’s first USB 3.0 signal quality test fixture. The complete solution enables engineers to quickly and accurately test their USB 3.0 designs.

Agilent’s solution will incorporate the final USB 3.0 specification announced by the USB-IF on 14 November 2008. USB 3.0, known as ‘SuperSpeed USB’ will deliver 10 times the data transfer rate of USB 2.0 and will manage power usage more efficiently. SuperSpeed USB will be necessary for data-storage devices transferring more than 25 Gbps. Industry experts expect manufacturers to adopt SuperSpeed USB by the end of 2009 and to have consumer products widely available in 2010. However, until the actual silicon is available for testing, no USB solution will be ready for official certification.

Agilent’s complete design, simulation and testing solution includes:

* Infinium DSO/DSA91304A 13 GHz oscilloscope for transmitter testing.

* USB 3.0 transmitter compliance test application.

* USB 3.0 test fixtures.

* J-BERT N4903A, a high-performance serial BERT with complete jitter tolerance test for characterising USB 3.0 SuperSpeed serial communication links.

* ADS simulation software for creating and analysing USB 3.0 channels.

* VNA/PNA network analyser N5230C-245 for measuring and analysing USB 3.0 channels.
