The Design of Multi-functional Signal-generator Based on FPGA and AD5422

Design a high-precision Multi-function signal generator based on AD5422, with FPGA as the core controller. The program achieve voltage and current signal output. It can output square wave, sine wave, triangle wave, constant voltage, constant current other waveforms of voltage and current signals, etc. with the frequency, amplitude adjustable within a certain range. And it designed interactive interface to make the operation intuitive and easy to use. The systems compared to conventional signal generator has the advantages of fast processing speed, convenience, flexibility, anti-interference ability and so on. After debugging the designed signal generator can meet the design requirements.
