Comparing intemet-enabled VNA measurements with primary national standards

This paper presents a comparison of measurements made between an Internet-enabled measurement facility and two primary national standard facilities. On this occasion, the client for the Internet-enabled facility was Agilent Technologies, South Queensferry, Scotland, and the UK's National Physical Laboratory (NPL) operated the primary national standard facilities. Both Internet-enabled and national standard facilities performed measurements of reflection coefficient and attenuation (i.e. S-parameters) at frequencies ranging from 05 GHz to 26.5GHz of coaxial devices fitted with precision 3.5 mm connectors.
