摘要
通过校准修正矢量网络分析仪全部12项系统误差,利用Matlab程序实现了SOLT(short、open、load、through)和TRL(through、reflect、line)校准算法,去除误差项,得到真实的S参数.通过与矢网校准结果相对比验证了算法和程序的正确性,并在此基础上制作了SOLT和TRL微带结构校准件,并成功用于滤波器测试.
Short, open, load, through (SOLT) and through, reflect, line (TRL) calibration techniques were described. The 12-term system errors for two-port calibration were shown, and the actual S-parame- ters device was derived from the measured S-parameters by using matlab programs. Comparison between the matlab programs results and the vector network analyzer measurement data validated the correctness of the calibration approaches and procedures. The SOLT and TRL microstrip calibration standards were de- signed for microstrip filter measurement
