摘　　要：使用矢量网络分析仪研究高速印制电路板差分阻抗折线设计各影响因素对高速信号插入损耗及回波损耗的影响情况。通过实验结果表明,不确定性度与折线夹角呈反比,随折线夹角增大而减小;不确定度与折线线长呈反比,随单段折线线长增大而减小。The influence of various factors on the insertion loss and return loss of high speed signal in differential impedance polyline design of high speed printed circuit board is studied by using vector network analyzer.The experimental results show that the uncertainty is inversely proportional to the Angle of the broken line,which decreases with the increase of the Angle of the broken line.The uncertainty is inversely proportional to the length of the broken line and decreases with the increase of the length of the single broken line.
