Compact Front End Board (C-FEB)
5-5-1
General Information
The main purpose of the Venue Fit™ Front End Board (C-FEB) is to transmit/receive all the channels
data signals to/from the 128 TRX channels on the board. In addition, it contains all the control and status
lines required for HV MUX setup, probe selection, reading probes status, probes information and the
power supplies for transmission and operation of the scanner.
The Venue Fit™ Front End Board is designed to support the cSound SW beam-forming architecture for
128 channels.
