Patent ID: 8504315

Claim:
A method for error correction of a vector network analyzer with at least two test ports, with the following method steps: performing a primary system calibration using a calibration kit, performing, via at least one processor, a first secondary error correction on relevant one-port networks of the vector network analyzer, performing, via the at least one processor, a second secondary error correction, wherein, after the first secondary error correction of at least two one-port networks and a determination of at least one of system parameters directivity, source match and reflection tracking on the one-port networks, the second secondary error correction is performed, wherein, for this purpose, the at least two one-port networks are through connected in an ideal manner and, taking into consideration system-error parameter(s) of the first secondary error correction for at least one frequency point of the test-frequency range, a scattering parameter matrix is measured, from this, an un-corrected scattering parameter matrix is determined and, from this, a corrected load match and/or a corrected transmission tracking in a forward and/or a reverse direction is determined.
