The RF input signal is converted into a standard 36 MHz IF frequency by a fully agile down converter. This signal is digitally filtered, elaborated, precorrected and then presented at 997 MHz to the channel converter. The channel converter provides to generate the final frequency in a fully agile mode.

Screen Service SDT ARK 1 ECHO Operations This tool provides two grids for the drawing of:  Module of the filter’s curve.  Group Delay of the filter’s curve. The two curves are used to calculate the linear pre-correction coefficients. The curves are drawn by the interpolation of 1024 points referring to the points inserted and using a linear or polynomial interpolation algorithm.
