Additional note: The topology network is N+3 (Node plus 3 amplifiers in cascade).
1.      The attenuation value measured in the last client, applying frequency swaps (reply in frequency), measured in the interval from 55MHz to 1 GHz for ‘forward’,
and shall be equal to 4dB. (Use fix attenuation value for use EQ/Attenuator).
2.      The attenuation value measured in the last client, applying frequency swaps (reply in frequency), measured in the interval from 5MHz to 42MHz for ‘rewind’,
and shall be equal to 2dB. (Use fix attenuation value for use EQ/Attenuator).
