DisplayPort link layer compliance testing

The Quantum Data 882E video generator/ analyzer is now approved by VESA for DisplayPort link layer compliance testing.
The approval includes compliance testing for both DisplayPort source and sink products against the requirements of the DisplayPort Certified Logo Program which currently uses version 1.1a of the link layer compliance test specification.
This will enable developers of DisplayPort products to perform fast and comprehensive compliance tests.
Operation is simple. The compliance tests are initiated through a user friendly graphical application. Developers can run tests in batch mode or individually. When a test series has been completed, the system issues a pass/fail result for each individual test. Reports can be viewed online, transferred over a network or printed.
The 882E provides other useful features for testing link layer interoperability. Optional feature for link layer transaction logging is the auxiliary channel analyzer. This enables developers to monitor link layer transactions in real time during normal operation or during a link layer compliance test. Developers of DisplayPort source devices can utilize the custom link training feature to force particular values into the 882E reference sink to test their source's handling of specific sink DPCD behaviors.
