In bit-serial digital coaxial interfaces for HDTV component signal data rates of 1.5 Gb/s are common. It is known that
a signal adhering to SMPTE 292M will ensure correct operation of automatic cable equalisers provided a coaxial cable
with a 1/ f frequency response from 1 MHz to the clock frequency is used.
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. The
individual cable lengths may be patched together to simulate a maximum length of 150 metres. The use of switches
has been avoided as they introduce unacceptable errors into the simulation.
