Claims

C1strongest claim

The system exploits the Short-Open-Load-Reciprocal technique to realize error-corrected cryogenic measurements within a single cooling cycle, with calibration standards referenced to SI-traceable room-temperature measurements and a numerical approach to evaluate response shift upon cooling for the uncertainty budget; test result on a 20 dB attenuator yields 20.70 +/- 0.08 dB at 6 GHz.

C2weakest assumption

The numerical approach used to evaluate the response shift of the artifacts upon cooling accurately captures all relevant cryogenic changes and derives a valid additional uncertainty contribution without significant unmodeled systematic effects or biases (abstract: 'a numerical approach is used to evaluate the response shift of the artifacts upon cooling and to derive an additional cryogenic uncertainty contribution for the measurement uncertainty budget').

C3one line summary

A calibration strategy and uncertainty budget for full two-port S-parameter measurements at mK temperatures over 4-12 GHz using SOLR in coaxial line with SI-traceable room-temperature references and numerical cryo-shift modeling.
