5.11 Verification of distribution networks
(SAT IF Test / Attenuation Test)
This application allows to verify easily the TCI features (Telecommunications
Common Infrastructures) before the antennas and head-end devices are operative. The
procedure allows to evaluate the frequency response of a whole TV signals distribution
network by means of two steps:
