| 摘 要： | 信号发生器是电路系统设计、测试的重要环节，也是电路课程相关实验的基本组成模块。现有的信号发生器硬件规模大，发生信号种类少，功能扩展需更改硬件电路，不能完全满足系统设计、测试和复杂实验需求。AD9857可工作于正交调制、单音、内插DAC等三种模式，内部集成DDS、DAC等模块，实现信号发生的基本硬件功能。对以AD9857为核心设计的基于计算机和基本硬件电路的信号发生器进行探讨。为信号发生器设计提供借鉴：为系统设计和测试，特别是为电路课程实验中信号源种类多的问题提供一种解决方案。

| Abstract: | Signal generator is not only an important part in circuit system design and test,but also the basic module in experiments of electric circuit course.The existing signal generators do not fully meet the system requirements of the system design,test and complex experiments,which have many defects such as more hardware scale,less kinds of signal,and more difficult expanding.AD9867 works in three modes,including quadrature modulator mode,sigle-tone mode and interpolation DAC mode.AD9867 integrates DDS,DAC,it ac... |
