摘要
在采用电压电平差法测量固有衰减时 ,由于测量仪器的输出阻抗、输入阻抗与被测信号传输线的特性阻抗的不匹配 ,将造成测量误差 ,本文详细论述其误差的修正。
Measurement of inherent attenuation by the method of voltage level gap has errors caused by the unbalance between the input/output impedance of the measuring instrument and the characteristic impedance of the signal wire under test. This article discusses in detail the rectification of the errors.
