摘　　要： 针对介质复介电常数测量自动化的需要,根据微扰法理论设计一套基于LabWindows/CVI的介质复介电常数的测量软件系统。该测试系统主要包括校准、矢网控制、计算三个模块。用户只需按照测试面板的提示即可完成对介质复介电常数测量。并创新性地提出直接将校准文件存于计算机内,这样可以大大减少测量时的校准耗时。测量结果表明,利用该测试系统测得的数据基本与标称值吻合,且该系统操作方便,性能优良,提高了测试效率,并具有良好的扩展性。 According to the practial need of automation and precition in the measurement of complex permittivity,an automatic measurement software system of measuring the complex permitivity based on LabWindows/CVI is designed. This system is composed of calibration, vector network analyzer controlling and calculation. Client can finish the calibration according to the instruction int the software panel. The calibration file can be stored in the computer so that the time of measuring can be reduced. The measurement results indicate that the obtained data is similar to documentary value,and the system can be operated conveniently and has good extensibility.
