| Abstract: | The principle and advantage of guided wave testing technology were introduced. Some analysis for parameters of incentive source has made,which was used in pipeline guided wave detector. On the basis of direct digital frequency synthesizer （DDS）,it focused on the use of DDS chip AD9850,microcontroller and high performance operational amplifier to design an incentive source for guided wave detector. Result showed that the design completely met the requirements, and had excellent frequency and phase output. It could be used for high accurate incentive source in practice. |
