摘　　要：设计实现了一种以AD9959为核心的二进制数字调制信号源,该信号源采用CPCI模块化设计,可将二进制调制数据调制到射频工作频率,产生多路2ASK/2FSK信号。该文从2ASK/2FSK调制原理入手,提出了基于AD9959的二进制数字调制信号源总体框架,并着重阐述了多路2ASK/2FSK信号的实现过程。该信号源已应用于某技改项目上,实际结果表明,该信号源产生的2ASK/2FSK信号频率分辨率高、抗干扰能力强、控制参数灵活,完全满足广播通信领域的功能要求。A kind of Binary Digital Modulationgenerator based on AD9959 is designed,The generator use CPCIModular design,the binary Modulation Datacould be modulated into RF directly,Multi- channel2 ASK and 2FSKsignal is achieved. The article starting with2ASK/2FSKModulation Principle,System framework of Binary Digital Modulationgenerator Based on AD9959 is gived,and mainly introducesthe Implementation Process of Multi- channel2ASK/ 2FSK. The generator have been applied in a improvement project,and the experimental results showed that the generator had several advantages such as high frequency stability、strong anti-jamming、parameters flexibly,which fully meet the function requirements in the Field of Broadcasting-Communication.
