Software streamlines eDP 1.4 testing

The eDP 1.4 software eliminates the need to tailor a test process for eDP designs. The software offers a flexible approach that all companies and sites participating in the eDP ecosystem can use to evaluate device performance and share test process information consistently across design and validation stages.

The test software operates on Keysight’s 90000 X-, 90000 Q- and Z-Series Infiniium real-time oscilloscopes with bandwidths of 13 GHz and higher. Access to the test signals through an eDP test fixture is required.

“Adopted by almost every new laptop computer maker, embedded DisplayPort is one of VESA’s most widely implemented standards,” said VESA Board of Directors Chair Alan Kobayashi, fellow and executive R&D manager for Smart Connectivity Group at MegaChips Technology America. “We welcome Keysight’s new product offering, which will enrich the universe of eDP design, validation and test resources. VESA is continually evaluating and enhancing its standards with new features and capabilities. Companies like Keysight enable the engineering ecosystem to keep pace with the rapid technical evolution of our standards.”

Keysight eDP1.4 test solution features include a full suite of tests leveraged from the DisplayPort 1.2b compliance test specification, the ability to select bit rates and nominal values for level and pre-emphasis as well as the number of settings for each, the ability to create test limits for each test according to design needs and a template-driven test capability for better productivity in repeatedly testing a given device type, or to share with others for identical tests
