The Teledyne LeCroy 980 DP Video Generator / Analyzer Module is a dual-function instrument for testing and validating DisplayPort interfaces across source devices, sinks, and repeater systems. It generates and analyzes video, audio, and protocol signals with full support for DisplayPort 1.2, 1.4, DP Alt Mode over USB-C, and Embedded DisplayPort (eDP). The module delivers end-to-end coverage for HDCP compliance, Display Stream Compression (DSC), Forward Error Correction (FEC), and comprehensive video parameter validation—making it essential for R&D, manufacturing, and quality assurance workflows.
