This contribution illustrates a multi-frequency calibration approach for reflectometer measwements. The described algorithm is based on the weD-known calibration procedure introduced by the 3-Term error model. Therefore, three difl'erent reflection standards are necessary to obtain the error terms of the reDectometer. In contrast to existing methods with calibration standards of different medlanicallengtbs as a sliding short, our approach uses a frequency shift to change the electrical length of a given reflection standard resulting in a new so-called synthetic calibration standard. Thus, the number of physical calibration standards can be reduced and no mecbanical displacements are required.
