The software eliminates the need to tailor a test process for eDP designs. It 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.

Running on Keysight’s 90000 X-, 90000 Q- and Z-Series Infiniium real-time oscilloscopes, the software requires an eDP test fixture to test the signals. Also required is an oscilloscope vertical bandwidth of 13 GHz or higher.

Adopted by most laptop computer makers, embedded DisplayPort is one of the most widely implemented standards when it comes to connecting video source to a display device

Keysight eDP1.4 test solution features include:

  • A full suite of tests leveraged from the DisplayPort 1.2b compliance test specification
  • Ability to select bit rates and nominal values for level and pre-emphasis as well as the number of settings for each

Ability to create test limits for each test according to design needs

  • Ability to create a test plan that includes selecting the device states for specific tests
  • Template-driven test capability for better productivity in repeatedly testing a given device type, or to share with others for identical tests
  • Ability to deviate from a given template to suit specific debugging needs

Users can create 20-, 30-, 40- or 50-pin eDP implementations using the IPEX connector system. Fixtures are available from Wilder Technologies and LUXSHARE ICT.
