Tektronix Launches Fully Automated Solution for DisplayPort Conformance Testing

Fully automated solution covering DisplayPort 1.2 conformance testing specification helps manufacturers accelerate time to market

Beijing, China, November 17, 2011 - Tektronix, a leading global oscilloscope market leader, has announced the launch of new software and test fixtures to provide fully automated compliance testing support for the DisplayPort 1.2 Compliance Test Specification (CTS). These new products are used with the Tektronix DPO/DSA 70000 Series digital oscilloscopes with 8 GHz or higher bandwidth to ensure reliable and repeatable test results.

DisplayPort is a digital display interface standard developed by the Video Electronics Standards Association (VESA) for connecting video sources to display devices such as computer monitors or televisions. Improvements to DisplayPort 1.2 include doubling the effective signal transmission speed to 5.4Gbit/s, multiple independent video streams (daisy chaining of multiple displays), support for 3D stereo, increased AUX channel bandwidth, and support for more color spaces. All test patterns of DisplayPort 1.2 CTS, such as SSC, CTLE, signal swing, bit rate, Post Curser 2 settings, and pre-emphasis levels, are combined into more than a thousand test patterns, all of which are covered by the new Tektronix solution.

"The complexity of DisplayPort state control and the large number of transmitter parameter configuration patterns make testing the CTS1.2 specification very time-consuming and challenging for those who are not particularly familiar with the specification," said Mike Rizzo, Oscilloscope Solutions Manager at Tektronix. "This solution from Tektronix provides customers with a comprehensive range of consistent measurement types while automating the entire measurement process, helping to save engineers valuable time and making the best use of equipment."

Fully Automated Testing
Using the new DisplayPort 1.2 software option on the DPO/DSA70000 Series oscilloscopes, engineers and technicians can perform fully automated testing of DisplayPort 1.2 designs with complete hands-off control. The DisplayPort 1.2 solution is implemented within the Tektronix TekExpress automated compliance test software, which provides simple setup and test execution. The DUT state control is fully managed through the Tektronix DP-AUX auxiliary controller and automated through the TekExpress test framework. The graphical user interface provides an intuitive setup and test workflow. Test results reports are generated upon completion of the test.

In addition to software support, Tektronix now offers a comprehensive DisplayPort 1.2 test fixture for signal source, cable and heat sink testing, including support for miniDisplayPort plugs, and 13 GHz differential probes that allow full four-lane parallel testing.

Tektronix is ​​the industry-leading supplier of DisplayPort test solutions that fully support the previous DisplayPort 1.1 specification and was the first supplier to achieve VESA certification. This latest product demonstrates Tektronix's continued leadership in providing powerful and industry-recognized test solutions for all major high-speed serial data standards.

Availability
DisplayPort 1.2 software and test fixtures are available now worldwide.
