6. BPM Analogue Processor Version 1 New PCB front-end processors designed and built – based on FONT3 processor (connectorised components) Integrated 2-channel board (sum and difference), ease- of-use (less set-up), greater reliability, simplified phasing of the local oscillator, optional amplifier mounting. Stripline Inputs Raw sum loopback LO input Difference output Sum (I) output Sum Q output

10. Future Work Modify Digital Board for minor errors or redesign its layout which needs more investigation of the board and finding its shortcomings Design a new board for FONT5 considering the experiences obtained from Digital Board, newer ADCs, DACs and FPGA Modify the layout of the BPM Analogue Processor considering the necessity of the output amplifiers or redesigning the board considering higher resolution Designing an FPGA board for signal simulation Is the design of the Kicker Amplifier final or some improvements or redesign are needed? The need of integrating the MiniCircuits Amplifier in our boards? Other considerations?
