摘　　要：用AD985 6正交数字上变频器件 ,通过软件控制进行数字信号处理得到两路正交信号作为AD985 6的输入信号进行调制 ,处理操作过程借助于软件来实现 ,因此程序操作简单可控。This paper adopts AD9856 cross digital up-transducer. By software control, we put up Digital Signal Processing to obtain two channels of cross signal as input signal for modulation. The process of disposal is completed in virtue of software. Therefore, the process is simple and can be controlled, has superior performance.
