摘　　要：目前复杂测试任务对信号发生器的要求越来越高,设计了一种基于FPGA/DDS的以可重配置合成仪器为核心架构的周期信号发生器,分析了信号发生器的总体设计方案,给出了系统的总体框架并分析了各部分的功能,介绍了硬件核心架构.在EADS newWaveX软件平台上验证了信号的准确度,并通过比较合成信号与模拟信号,验证了利用FPGA/DDS设计周期信号发生器的合理性与可行性.Under the circumstances that the present-day complex testing tasks establish increasingly higher requirements for signal generator,the authors design a FPFA/DDS-based reconfigurable periodic waveform generator system with the composite equipment as the core structure.They analyze the overall designing plan of the signal generator,present its overall structure and the functions of relevant components,and introduce the core structure of the hardware.Finally,they test and verify the accuracy of signals on the software platform of EADS newWaveX and the rationality and practicality of the signal generator system.
