摘　　要：本文介绍EMI滤波器的静态指标（直流阻抗）和瞬态指标（插入损耗）的测试原理和方法。通过LabVIEW的图形化编程实现自动化测试，实现批量产品的信息显示、数据采集、数据显示、数据存储等功能。该系统的实现，提高了EMI滤波器的测试效率，减少了因人为操作对测试结果引起误判事件的发生，对产品的高低温测试数据的准确度和稳定度都有较大的改善，并且能够根据测试对象的不同需求随时改变测量参数。This article describes the testing principles and methods about static indicators（ DC resistance）and dynamic indi- cators （ insertion loss） of the EMI filter. Completing automated testing by the LabVIEW graphical programming, and achieving in- formation display,data acquisition,data display, data processing, and data storage of mass products and other functions. Imple- mentation of the system,the test efficiency of the EMI filter is improved. It can reduce the incidence of false event caused by hu- man actions on the test data, and the accuracy and stability of high and low temperature test data are increased. Also it can change the measured parameters of the test object according to the different needs at any time.
