Abstract

National Research Council Canada (NRC) recently established an AC Josephson Voltage Standard system based on NIST pulse-driven Josephson junction arrays. This paper describes the efforts undertaken at NRC and the experience that was gained. An experimental method of measuring corrections of the probe lead errors is described and first results are reported. By introducing ACJVS, NRC can now reduce thermal transfer standard calibration uncertainties 3-fold on the 200 mV range and 5- to 10-fold on the 20 mV range, in comparison to TVC- and micropotentiometer-based calibrations.
