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. 155) and easily observe the
measurement result thanks to the graphic display (fig. 156). 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.

The channel scan function allows you to quickly test the order and gain of the T / T2 system. It is possible to select the
range of steps and the end frequencies and scan all the signals within the band on one of the bandwidths of 6, 7 or 8
MHz (fig. 157-159).
Since there may be some amplifiers on the terrestrial TV antennas, it is possible in this case to select a supply voltage
of 5V, 12V, 20V at the output.

A table similar to that of fig. 160 will appear by scanning the selected band. Going to a frequency in the table and
pressing ENTER it is possible to measure the channel in real time.
Then pressing the EDIT button it is possible to download the signal parameters to a USB memory (fig. 161).
