Ferrero, A. 6579057 Corpus ID: 12712854; Measurement uncertainties due to non-ideal calibration standards for unknown thru calibration @article{Lenk2013MeasurementUD, title={Measurement uncertainties due to non-ideal calibration standards for unknown thru calibration}, author={Friedrich Lenk and Ralf Doerner and Paul Kurpas and Andrej It allows the thru to be unknown, other than it must be reciprocal. For this purpose, the software includes an UNKNOWN THRU standard in the description of each predefined calibration kit. Unfortunately in many applications, for example when measuring MMIC or on-wafer devices with not aligned ports, a custom thru line must be used. Typical calibrations are 12-term, but the quad-RX architecture reduces some errors so much that the much simpler 8-term calibration can be used, reducing calibration time. This is less than the minimum number of Thrus of a standard 4-port Cal.
