| Abstract: | 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. |
