The Teledyne LeCroy Quantum Data 780 is a portable, handheld digital video generator and analyzer purpose-built for HDMI source and sink testing, cable verification, and multimedia device troubleshooting. Operating across HDMI 1.4b compliance, it delivers pixel rates to 225 MHz on output and 150 MHz on input, supporting 1080p resolutions with deep color at 24/30/36 bit depths and 3D formats including Side-by-Side, Top/Bottom, and Frame Packing. The instrument integrates protocol analysis for HDCP (1.4 and 2.2 variants), EDID emulation and monitoring, CEC control, InfoFrames, timing data, and SCDC, alongside audio format support spanning LPCM at 32–192 kHz sampling rates and Dolby/DTS codecs. A color touch screen interface enables rapid on-site operation in R&D, manufacturing, and field service settings.
