Uncertainties in the Measurement of AC Voltage Using a Programmable Josephson Voltage Standard and a Phase-Sensitive Null Detector

Providing the traceability of alternating-current (ac) voltage measurements by means of a stepwise-approximated sine wave (SASW) produced by a programmable Josephson voltage standard (PJVS) is an attractive alternative to the conventional ac voltage standards based on thermal voltage converters, because a programmable Josephson standard has a calculable… CONTINUE READING
