ABSTRACT:
The invention relates to a method for correcting errors by de-embedding scattering parameters of a device under test associated with measuring ports (11), the parameters being measured by a vector network analyzer including n measuring ports. The aim of the invention is to create a universal, precise and fast method of correcting errors of scattering parameters. To this end, the method includes the following steps: formula (1) two-port calibrations are carried out on different calibrating standards in any order in the active state between the measuring ports (11), as a basis for a first error correction; the reflection parameters of at least one part of the n measuring ports (11) are determined in the inactive state, by way of the results of two-port measurements carried out on at least one calibrating standard switched in the active and/or inactive state on measuring ports (11), as a basis for a second error correction. The invention also relates to a network analyzer and to a switching module for a network analyzer.
