As DisplayPort evolves to support ultra-high resolutions and increased data rates, robust compliance testing is essential to ensure interoperability across devices and interconnects. This application note provides a structured overview of physical-layer testing for DisplayPort source transmitters and passive cables, aligned with VESA CTS v2.1. The note covers key test procedures using Rohde & Schwarz solutions, including oscilloscope-based measurement at standardized test points, automated test execution with ScopeSuite, and signal integrity debug via equalization and jitter decomposition. It further details cable characterization using mixed-mode S-parameter analysis on a Vector Network Analyzer (VNA), with support for simulated eye diagrams and TDR-based impedance diagnostics. Practical setup examples and product references are provided to help engineers perform repeatable, standards-compliant DisplayPort PHY validation.
