矢量网络分析仪的维护

Maintenance of Vector Network Analyzer

矢量网络分析仪不仅能测量网络的幅频特性而且还能测量相频特性和群时延特性。校准过程考虑了所有的主要系统误差来源,并能进行很精确的测量,其优异的性能和丰富的功能非常适合网络参数的测量需求,因此广泛应用于研发和生产。本文结合了多年的实践经验积累,介绍了如何保持矢量网络分析仪常处于可靠运行状态,以及对出现问题的分析和最佳解决途径。

The vector network analyzers can measure not only the amplitude-frequency but also the phase-frequency and group delay of the network. The calibration pro- cess accounts for all major sources of systematic errors and permits very accurate measurements. Their excellent perfor- mance and plentiful function can meet. the measuring re- quirements of the network parameter, so it has already been widely used in the researching and manufacturing. This pa- per presents how to maintain vector network analyzer in a regular and reliable operation of state, as well as the analy- sis of the problem and the best solution.
