摘　　要：LabWindows/CVI是一款面向测控领域的开发工具,而Matlab则是一款在数学领域中优秀的软件。在结合两者优势的基础上,提出了利用软件补偿来满足高频信号功率测试精度需求的方法。首先利用Matlab对某平台高频传输通道建立功率衰减模型,之后根据此模型采用LabWindows/CVI控制测试仪器资源对所得到的高频信号功率值予以补偿。最后,对已知高频信号源进行测试,所得测试数据满足平台测试精度要求。LabWindows/CVI is a software development tool applied to the field of observation and control,while Matlab is an excellent math software.In combination with the advantages of both mentioned above,a method to meet the requirement of the high-frequency signal power testing accuracy by software compensation is proposed.A power attenuation model of high-frequency transmission channel is established with Matlab,and then based on the model,LabWindows/CVI is used to control the testing instruments and compensate the measured power value of high frequency signal.At last,the known high-frequency signal source is tested.The tested result satisfies the requirement of testing accuracy of platform.
