The Teledyne LeCroy 780C is a portable handheld video generator and analyzer for testing digital video devices and network distribution systems across HDMI, HDBaseT, and 3G-SDI interfaces. Dual Tx/Rx ports enable source and sink emulation, supporting end-to-end validation of video sources, displays, audio devices, distribution equipment, and cables. A 7-inch color touchscreen provides real-time status and access to an extensive library of routine and diagnostic tests.
