displayport: compliance and signal integrity debugging -55体育

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.
