摘要
将数字直接频率合成技术(DDS)同虚拟仪器技术结合可有效解决传统信号发生器体积大、携带不便、通信接口少、不具备网络功能的缺陷,以及一般虚拟信号发生器生成高频信号困难的问题.为此,利用LabVIEW虚拟仪器软件设计上位机控制软件平台,利用DDS器件构建信号发生硬件平台.借助以太网将软硬件平台连接起来共同构成以太网DDS信号发生器,并且以具体实例详细讨论了该信号发生器软硬件平台的设计.
Direct digital frequency synthesis （DDS） technology combined with the virtual instrument technology can be an effective solution to the traditional signal generator bulky carrying inconvenience, communication interface less, and no network capabilities, as well as general virtual signal generator for generating high-frequency signal difficulty. For this purpose, a design plan of PC control software platform was proposed by using LabVIEW virtual instrument software, the hardware platform was constructed by using DDS signal device, software and hardware platform were connected to construct a common DDS signal generator by Ethernet. The particular design of signal generator hardware and software platform is discussed by specific examples.
