4.5.2.6 TX IF I
NTERFACES
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.
