Traceability via the Internet for microwave measurements using vector network analyzers

The Internet has been utilized to provide highly efficient and cost-effective measurement services using vector network analyzers (VNAs). Remote calibration and measurement using VNAs from two of the leading instrument manufacturers has been achieved with direct access to primary national measurement standards and procedures, via the Internet, for microwave frequencies in the range 45 MHz to 110 GHz.
