试验设计在PCB阻抗、插入损耗测量中的应用

Application of Experimental Design in Measurement of PCB Impedance and Insertion Loss

本文将通过试验设计的方式对网络分析仪的测量能力及配套的辅材进行分析评价。以PCB成品板的阻抗、插入损耗模块为测试对象,分析在Delta L和AFR测试条件下,不同测试方法测得的阻抗和插入损耗数值产生差异的原因,进而为后续网络分析仪的使用和维护提供帮助。

This paper will analyze and evaluate the measurement ability and supporting auxiliary materials of the network analyzer through the way of experimental design.Taking the impedance and insertion loss module of finished PCB board as the test object,this paper analyzes the reasons for the differences between the impedance and insertion loss values measured by different test methods under Delta L and AFR test conditions,thus providing help for the use and maintenance of the network analyzer in the subsequent.
