Abstract :
We use a general description of transmission lines to develop analytic descriptions for offset OSLT (Open-Short-Load-Thru) standards used to calibrate vector network analyzers. We then formulate approximations for coaxial standards that implement the equivalent circuit parameters in common use. A comparison of calibrated verification device measurements demonstrates that our representations agree well with the models used in commercial instruments.
