Four-port de-embedding analysis method based on S2P file and medium

The invention discloses a four-port de-embedding analysis method based on an S2P file and a medium, and relates to the field of port de-embedding, and the four-port de-embedding analysis method comprises the following steps: connecting a test fixture and a measuring device to measure original data; carrying out calculation by using 12 error term models; the six forward error terms are EDF, ESF, ELF, ERF, ETF and EXF, the six reverse error terms are EDR, ESR, ELR, ERR, ETR and EXR, and a 4 * 4 error term array is used for representing all error terms of the four ports; updating the 4 * 4 error term array by using the test fixture characterization file; and calculating an S parameter by using the updated 4 * 4 error term array. Through formula calculation, the S2P file is used through the global error term array, so that the computational logic complexity is reduced. 本申请公开了一种基于S2P文件的四端口去嵌入分析方法和介质，涉及端口去嵌入领域，本申请包括，连接测试夹具和测量器件测量原始数据；使用12项误差项模型进行计算；6个前向误差项：EDF,ESF,ELF,ERF,ETF,EXF，6个反向误差项：EDR,ESR,ELR,ERR,ETR,EXR，其中用
