The Teledyne LeCroy 780D HDMI Protocol Analyzer/Generator is a dual-function test instrument for HDMI and HDBaseT interface validation. It operates as both protocol analyzer and signal generator, combining real-time monitoring, compliance testing, and pattern generation in a single portable platform. The 7-inch color touchscreen provides direct access to protocol diagnostics, video pattern libraries, and audio verification tools—enabling field deployment and lab-based validation of digital video sources, sinks, cables, and distribution networks.
