A Method for the Correction of N-Ports Scattering Parameters Measurement

In this paper, a method used to reduce the errors in the scattering parameters measurement of N-ports based on two-port vector network analyzer (VNA) is presented, which is based on the normalization and renormalization of the scattering matrix, formulated equations are introduced to correct the reflective parameters of terminations according to the transformed scattering matrices, and an optimization procedure is given to precise the values of reflective parameters, the errors of the scattering parameters can be reduced for the corrected reflective parameters. The corrected method is proved by measured results
