Approval covers link layer tests for sink devices in accordance with
the requirements of the DisplayPort Certified Logo Program
Elgin IL - December 30, 2008 - Quantum Data, a worldwide provider of video test equipment, announced that their 882E test instrument has been approved by VESA for testing link layer compliance on DisplayPort sink products against the requirements of the DisplayPort Certified Logo Program. The VESA approval was against draft 19 of the Compliance Test Specification which should become standard Version 1.1 next month.
The link layer test application-developed in close collaboration with leading silicon vendors -
enables manufacturers of DisplayPort devices to bring fully compliant products to market faster and without interoperability issues.
"Developers working to bring new video technologies such as DisplayPort to market require test tools to help ensure interoperability and compliance." remarked Bill Lempesis executive director, VESA. "Approval of the Quantum Data 882E for link layer compliance test is a welcome addition to this set of tools."
The VESA approved link layer compliance test is another piece of a comprehensive set of solutions for DisplayPort testing. The 882E also provides an HDCP compliance test application which leverages the expertise Quantum Data gained through successful DCP approval of the HDMI version of the HDCP compliance test. Additional compliance tests are planned for release in the near future.
Recently, Quantum Data announced the result of a collaboration with Agilent Technologies in the development of a DisplayPort test solution that fully automates physical layer testing of the DisplayPort main link for sink- and source-device testing.
To complement the compliance test solutions, the 882E provides an Auxiliary Channel Analyzer which enables developers to examine the details of transactions occurring over the DisplayPort Aux Channel. This useful analysis tool monitors MCCS commands, EDID reads, link training and HDCP handshaking during normal operation or during compliance testing.
Operation of the link layer compliance test is simple. Test personnel define the capabilities of the device under test through a form and then initiate the test suite through a GUI application. Once initiated, the tests run continuously until completion without requiring user interaction. The Auxiliary Channel Analyzer can be used to monitor the link layer transactions during the compliance test to provide additional insight into any failures that might occur. When a test series has been completed, the application issues a report that provides summary pass/fail results for each individual test and extensive detail about each distinct step for all tests. Reports can be viewed online, transferred over a network or printed.
