The international standards body, the Video Electronics Standards Association (VESA), has certified Anritsu Corporation’s receiver test (SINK Test) solution for the most recent DisplayPort 2.1 standard. Data transmission quality and calibration can be automatically verified by combining Anritsu’s Signal Quality Analyzer-R MP1900A with automation software from Granite River Labs (GRL) or Teledyne LeCroy.
Digital transmission of high-definition, high-refresh-rate video, including 8K, is made possible via DisplayPort 2.1. The development of the standard is ongoing. DisplayPort 2.1’s adaptability and use in a variety of applications have significantly increased after the USB Type-C requirements were incorporated.
Nevertheless, the complexity of the test equipment settings and the drawn-out configuration and test methods make it difficult to manually verify transmission signal quality and calibrate, which presents a hurdle to the development of products that adhere to the new standard.
By automating the testing and calibration procedures, this solution increases development efficiency and guarantees the quality of video data transmission.
