为满足通信继转站故障测试时频率转换、相位噪声性能好的要求,介绍一种以DDS（AD9852）为频率合成核心芯片、单片机（C8051F020）为数据处理器的高速频率合成系统的设计方法,并详细地介绍了系统的组成,给出了系统在扫描和单音工作方式下的测试结果。实验结果表明,该方案完全符合设计要求。

In order to meet the needs of frequency conversion and good phase noise performance for testing communication transfer station faults, a high speed frequency synthesis system with AD9852 as frequency synthesis chip and C8051F020 MCU as the data processor was designed in this paper. And a detailed introduction of the system composition was given. The system test results were presented in scanning and monophonic mode. The experimental results show that...
