| 摘 要： | 采用基于波传播矩阵（T-Matrix）的10项误差模型对三通道二端口矢量网络分析仪（Vector network analy-zer,VNA）进行短路-开路-匹配-直通（SOLT）校准,校准过程中只需计算并保存两个特征变量,即可推导出二端口待测件（Device Under Test,DUT）的T矩阵,进而得到待测件（DUT）的散射矩阵。与传统的SOLT校准相比,这种算法不必计算各个系统误差项,DUT的散射矩阵直接由校准和测试过程中的散射参数测量值表示得到。最后,利用此方法计算二端口待测件的真实散射参数,并与传统的SOLT算法进行对比,其结果吻合良好。

| Abstract: | A simplified calibration procedure using T-matrix concept is presented for two-port vector network analyzer(VNA) with three measurement channels.Compared with Short-Open-Load-Thru(SOLT) calibration method based on 10-term error model where 10 error terms must be solved and saved at each frequency,the proposed method need define fewer characteristic variables.Simple formulas involved in calibration procedure are rederived for two-port VNA and only two characteristic variables need be calculated by the measur... |
