The Faraday HDTV cable clone has a known, accurate loss vs frequency characteristic against cable over the significant frequency spectrum of the serial digital signal. It can therefore be used as a more convenient substitute for actual cable when installing or testing HDTV serial digital equipment to ensure sufficient margin (head room) is available, or to establish the maximum length of cable over which the serial digital signal will remain usable.
