英文摘要：

In the field of wireless, network analyzer is a new measuring instrument in recent years and it develops in high speed. It is mainly used to measure the four terminal network, filter, and amplifier and so on. The analogue filter and amplifier were replaced and network analyzer makes the measurement more automatic and accurate. This article mainly discussed the structure principle and the use of network analyzer. The sample cables were measured, and compared with the industry standards.
