CHESTNUT RIDGE, N.Y.--(BUSINESS WIRE)--Teledyne LeCroy, part of Teledyne Technologies Incorporated (NYSE:TDY), today announces support for DisplayPort™ 2.1 physical layer (PHY) compliance testing in its second-generation QualiPHY 2 automated compliance test framework. Teledyne’s QualiPHY 2 software runs on Teledyne LeCroy oscilloscopes, performing standardized physical layer tests of high-speed serial data technologies such as PCI Express®, USB, Thunderbolt™, DisplayPort and HDMI®. The new QPHY2-DP2-SOURCE-TX and QPHY2-DP2-SINK-RX products run either on a Teledyne LeCroy oscilloscope or offline on a host PC installed with the QPHY2-PC option.DisplayPort 2.1 provides ultra-high resolution and fast display refresh rates using ultra-high bit rates (UHBR) and multiple serial data lanes. This combination of capabilities requires extensive testing to ensure compliance test specification (CTS) requirements are met. Despite this, DisplayPort links that pass compliance testing often fail interoperability tests, decreasing end-user satisfaction.Teledyne LeCroy’s VESA-approved QualiPHY 2 DisplayPort 2.1 PHY compliance test software options run on a Teledyne LeCroy oscilloscope in the lab to automate both Source (Tx) and Sink (Rx) testing in a single test framework. QPHY2-PC offline compliance test software provides flexibility to complete the testing outside the lab using already captured data. Used together, these products eliminate laboratory bottlenecks, performing validation and compliance tests in a fraction of the time required by previous products. The complete compliance test solution consists of:<ul><li>New QualiPHY 2 options QPHY2-DP2-SOURCE-TX and QPHY2-DP2-SINK-RX that support all UHBR, HBR and RBR test requirements, and QPHY2-PC option for offline analysis</li><li>QualiPHY 2-driven Device Under Test (DUT) automation using AUX controllers from Unigraf (UCD-323) and Wilder Technologies (DPAC-CAM)</li><li>WaveMaster 8000HD oscilloscope that performs both high-speed compliance testing and low-speed sideband interoperability debug testing</li><li>Anritsu SQA-R MP1900A Signal Quality Analyzer for DisplayPort 2.1 stressed signal generation during Sink (Rx) testing</li><li>WavePulser 40iX High-speed Interconnect Analyzer to automate S-parameter measurements for cable de-embedding, Tx/Rx return loss testing and Rx channel calibration</li><li>SDA Expert for DisplayPort (SDAX-DP) software to analyze signal quality during training</li></ul>The VESA PHY CTS does not expressly describe or require interoperability testing between Sources and Sinks. However, failures of PHY-Logic communications when setting up the Source-Sink link will lead to dropped display connections, timeouts or reduced resolution. Teledyne LeCroy’s interoperability debug solution improves end-user satisfaction. It consists of:<ul><li>WaveMaster 8000HD oscilloscope with both 50 Ω (high-speed) and 1 MΩ (low-speed) inputs, optimized for simultaneous acquisition of the SBU/AUX electrical signal and Main Link high-speed signals</li><li>DP-AUX TDMP and USB-PD TDMP software options to trigger on and decode any AUX channel or USB-C power delivery message, helping to debug Source and Sink link negotiation</li></ul>“Teledyne LeCroy is pleased to meet the need for fast and efficient DisplayPort 2.1 PHY compliance testing, and to provide interoperability debug tools to ensure that developers are able to meet end-user expectations for the highest performance possible with DisplayPort 2.1 UHBR speeds,” said Tyler Cox, Vice President, General Manager Scopes/Digitizers.For more information about Teledyne LeCroy’s DisplayPort 2.1 test solutions, visit: https://www.teledynelecroy.com/displayport-phy-test/.To access Teledyne LeCroy’s approved PHY test Methods of Implementation (MOI), visit: https://www.teledynelecroy.com/resources/details.aspx?doctypeid=2&amp;mseries=654About Teledyne LeCroyTeledyne LeCroy is a leading manufacturer of advanced oscilloscopes, protocol analyzers, and other test instruments that verify performance, validate compliance, and debug complex electronic systems quickly and thoroughly.
