System and method for calibrating a network analyzer and characterizing a measuring fixture

摘要

A method and a system for calibrating a network analyzer using a 16-term error model determines a matrix (A) with measured scattering parameters (Sm) of different calibration standards (3) and associated actual scattering parameters (Sa) of the calibration standards (3) and determines linearly -in-T system errors (T ~ i) for calibrating the network analyzer (1) by solving a linear system of equations with the determined matrix (A). For solving the linear system of equations, first and second linear-in-T system errors (k, p) are each freely chosen. When using reciprocal calibration standards, the determined linear-in-T system errors will become the second system selected linear-in-T error (T ~ i) or a second correct one dependent on the first linear-in-T system error (k) linear-in-T system error (pkor (k)) weighted.
