The Tx IF input signal is fed from the customers equipment to the RSU-5060 at
connector J6. The RSU-5060 contains a power splitter which feeds the IF input
signal to both CSAT A and CSAT B via the J7 and J8 connectors. The IF power
at J7 and J8 will nominally be 3dBm less than the IF input power at J6.
