基于LABVIEW的数字合成信号源设计

Design of digital synthesis signal source based on LABVIEW

传统仪器根据不同的功能要求采用不同的硬件结构,受生产厂家定义仪器机箱的约束,功能由其硬件结构固定死的,很不灵活。基于虚拟仪器编程语言LabVIEW的数字合成信号源,使用户根据自己的需要,利用LabVIEW丰富的资源,能实现方波和正弦波等多种波形在较大的频率范围内的输出,满足多种多样的应用需求。对设计的数字合成信号源运行结果进行分析,验证了数字合成信号源设计的正确性。数字合成源大大突破传统仪器在信号的种类少、频率范围小、升级困难等方面的限制,还降低了成本,达到传统仪器无法比拟的效果。

According to different functions,traditional instruments require different hardware architecture.All the functions are fixed by hardware architecture and very flexible because manufacturer constraints the instrument chassis.The Digital Synthesis Signal Source,based on the virtual instrument programming language LabVIEW,allows the users to achieve many kinds of waveform output in the big frequency range,such as the square-wave and the sine wave,etc…Therefore,the diverse requirements can be met by use of the rich resources of LabView.The running results of the designed Digital Synthesis Signal Source has been analyzed and the correctness of the designed Digital Synthesis Signal Source has been verified.Digital Synthesis Signal Source substantially has not only broken through the traditional instruments in data processing,transfering and other restrictions on convenience,but also reduced the cost so that traditional instruments are beyond incomparable results.
