The article introduces how to achieve the arbitrary waveform generated system based on the single chip using Direct Digital Synthesis（DDS）technology,whose core module - DDS is realized by FPGA chip. The waveform generated system can produce many kinds of waveforms. The waveforms are of high - frequency resolution, wide bandwidth, while achieving phase regulation functions. This article mainly introduces the design of the system core module, and gives specific theoretical and experimental data analysis conclusions.
