Towards establishing traceable coaxial Type-N scattering-parameter measurements at NIT

We present results of our work aimed at establishing traceable coaxial type-N vector-network-analyzer scattering-parameter measurements at the National Institute of Telecommunications, Poland. To this end, we employed a set of high-grade coaxial air-dielectric transmission lines as the primary calibration standards and a calibration procedure based on the multiline through-reflect-line method. In order to verify our procedure, we compared it with the calibration procedure implemented in the vector-network-analyzer and based on an electronic calibrator. Preliminary experimental results show very good agreement between the two procedures.
