The Tilt / Limit test is an efficient solution to check the order of the cable system and the further weakening of the
signal at high frequencies. It is possible to acquire the signal levels of 12 channels (fig. 111) and easily observe the
measurement result thanks to the graphic display (fig. 112). It is possible to select the first 6 frequencies of the group
starting from the beginning of the television band and the last 6 frequencies starting from the end. Then you can control
the slope and arrange the amplifiers and distribution elements based on this inclination.
