Effects of adapters present only during calibration of a network analyzer are removed. Scattering parameters are obtained for the adapters. For example, the scattering parameters for the adapters are obtained by characterizing the adapters. Systematic error terms for the calibration which remove adapters effects are generated using the scattering parameters for the adapters. In one embodiment, the scattering parameters for the adapters are used to pre-load adapter error terms into the network analyzer before the calibration. The calibration is then performed with the adapter error terms pre-loaded to generate systematic error terms for the calibration. In an alternative embodiment, the calibration is performed (without pre-loading error terms) in order to generate preliminary systematic error terms for the calibration. The preliminary systematic error terms and the scattering parameters for the adapter are used to generate the systematic error terms which do not include effects of the adapters.
