VESA Approves Tektronix DisplayPort Cable Testing Methods

Tektronix India, a leading worldwide provider of test, measurement and monitoring instrumentation, announced that the Video Electronics Standards Association (VESA) has approved the Tektronix Method of Implementation (MOI) for testing interconnect cables according to the DisplayPort 1.1a specification, the first MOI in the industry for DisplayPort 1.1 cable testing. The Tektronix methodology eliminates the need for expensive and complicated instruments promoted by alternative solutions. The new MOI and complete Tektronix DisplayPort test offering can be viewed at www.tek.com/displayport.

DisplayPort is the new digital display interface technology for computers, monitors and home-theater systems aimed at lower implementation costs and improved video performance. DisplayPort gives manufacturers of LCD panels, monitors, graphics cards, PC chipsets, projectors, peripherals, components, cables, and consumer electronics a next generation digital interface that is designed to replace LVDS, DVI, and eventually VGA.

The Tektronix interconnect MOI specifies a DSA8200 Digital Serial Analyzer and TDR/TDT and S-Parameter support through iConnect® software. This is the only approved single instrument DisplayPort interconnect test solution in the market for passive cables. Testing active cables additionally requires an AWG7102 Arbitrary Waveform Generator and 80SJNB jitter analysis software. Unlike alternative solutions that require expensive, complex instruments and setups the Tektronix configurations efficiently ensure a readable signal reaches the receiver

The Tektronix approach successfully performed the needed DisplayPort cable tests,” said Doron Lapidot, director of engineering, Circuit & Design Asia Pacific and EMEA, Tyco Electronics. “The Tektronix solution provides the needed compliance testing with reduced cost and complexity. We’ve selected this configuration as part of our DisplayPort interconnect testing.

“The DSA8200 measurement system provides channel characterization with TDR/TDT and S-Parameter support,” said Ian Valentine, general manager, Technology Solutions Group, Tektronix. “The acceptance of our DisplayPort MOI for interconnect testing by VESA and adoption by forward-looking organizations like Tyco Electronics demonstrate the utility and cost-effective advantages of the Tektronix tools and methodology.”

Tektronix has received VESA certification for source, cable, and sink compliance test solutions. “Tektronix is recognized around the world for its leadership in test solutions including DisplayPort,” said Bill Lempesis, executive director, VESA. “These tools enable companies to efficiently test their designs, helping to expedite compliance with DisplayPort through the CTS defined within the standard. The efforts of Tektronix increase the overall set of tools that companies have available to assist in DisplayPort development and industry adoption.”
