Test HDMI source compliance with an oscilloscope

Testing high-definition multimedia interface (HDMI) 2.1 source devices requires authorized compliance testing by the HDMI Forum to ensure seamless interoperability. Backward compatible with earlier versions of the HDMI specification, HDMI 2.1 significantly increases transmission bandwidths up to 48 Gbps. HDMI 2.1 compliance source testing requires a high-performance real-time oscilloscope to capture and analyze a wide range of test patterns and the ability to include transfer functions, filters, different fixtures, cable models, skew, and equalizers.

A source device outputs video at various data rates for testing purposes. Use an oscilloscope and compliance test software to automate the testing process. This setup provides a detailed analysis of the test results, clearly highlighting each test’s pass or fail margins. The testing of HDMI devices must follow the HDMI Forum’s General Compliance Test Specifications and the approved Method of Implementation (MOI).
