基于虚拟仪器的信号源产生控制技术研究

Control Technique to Signal Generator Based on Virtual Instrument

分别以LabVIEW8.5和LabWindows CⅥ9.0为开发平台,构建基于Agilent信号源的虚拟信号源来控制产生各类激励信号.各类信号产生过程均采用Event Structure事件触发模式来实现,能够方便地对信号产生进行控制和实现,并对两种控制仪器的实现方法进行了比较.整个设计方法在合成孔径雷达(SAR)系统集成测试中得到了较好的应用.

Virtual instrument control technique based on LabVIEW8.5 and LabWindows CVI9.0 environment respectively is used to simulating the Agilent signal generator to produce various stimulated signal. Various signal generation process is realized by the event structure mode so that the signal generation can be controlled and implemented conveniently. Comparison between two control instrument methods is given. The whole design has been applied well to the system integrating test of Synthetic Aperture Radar （SAR）.
