To solve the problem of some type nonstandard impedance filter measure owing to sweep generator＇s aging, an impedance matching circuit is designed to measure filters by network analyzer. In this paper, measuring principles of sweep generator and network analyzer are introduced as well as their differences. The implement of net- work analyzer HP E5100B instead of sweep generator JW1252W in filter measure is given, and the principles of impedance matching circuit and its application in filter measure are expatiated. Experiments show that the use of the network analyzer can guarantee the consistency of numerical values to be measured. This method also has the advantages of easy operation and high precision and it can save labor and cost.
