An AC Josephson voltage standard system for frequencies up to the kHz range tested in an industrial environment

This paper describes the performance of a new turn-key AC quantum voltmeter, an AC Josephson voltage standard system, used for calibration of common DC and AC voltage standards. The capabilities and handling of the system in an industrial environment were investigated and are discussed here. Several Fluke 5700A series calibrators were tested and their voltage and frequency dependence is characterized in the range of DC to 1 kHz with amplitudes up to 10 V. The combined measurement uncertainty for AC measurements was determined to be less than 1 μV/V.
