摘要
介绍一种采用SOPC技术设计的DDS任意波形发生器。该任意波形发生器采用了FPGA+USB通信芯片的硬件架构,具有即插即用的特性,能实现两路可调相位差的任意波形输出,波形频率分辨率达到0.1Hz。设计中对DDS的结构进行了改进,使其可以在波形切换时实现平滑输出。
A new design of arbitrary waveform generator（AWG） based on DDS, with SOPC technology adopted, was introduced in this paper. In the design, FPGA plus USB device were employed in AWG, The designed generator has the function of plug and play, transmitting two channels of arbitrary waveform whose phase-difference was adjustable. The AWG＇s frequency resolusion reached 0,1Hz. In addition, the structure of DDS was improved to keep output smooth at the time of the waveform data changing,
