Abstract
An RF network analyzer is disclosed which is suitable for both laboratory and automated production measurements. An important feature of the invention is the ability of the user to completely specify the method of calibration to be used. In particular the user can select any three arbitrary RF standards having known electromagnetic response characteristics and can attach them in any arbitrary order to perform the calibration of the instrument. This calibration is carried out by measuring the RF scattering parameters S.sub.11, S.sub.21, S.sub.12, and S.sub.22, storing the data in a memory, and then calculating vector error correction coefficients that are characteristic of systematic errors introduced by the RF network analyzer into measured scattering parameters.
