Analog Receive Signal Path and Analog Rx Path

Figure 7-183 Card Rack - GFI configuration
Echoes received by transducer pass through the GRLY Board, across the Front Planes and to the GRX
Board.
The GRX Board amplifies the signal and passes it to the DRX Boards via the Backplane.
The DRX Boards convert the analog signal to a digital signal which then gets passed on to the GFI
Board.
The GRX64 Board passes signals to the DRX1 Board.
The GRX128 Board passes signals to DRX2 and DRX3 Boards.
