Abstract: This paper presents results of an international comparison of two quantum AC voltage standards based on pulse-driven Josephson arrays. The two systems differ in several hardware and software characteristics as well as in the level of automation, features which can influence the accuracy of transferring the quantum-standard voltage value to a calibrated instrument. The comparison was performed at 100mV, 20mV and 12mV, at frequencies between 2.5kHz and 100kHz. An electronically-aided thermal transfer standard was used as a travelling standard. At the most accurate voltage and frequency point, 100mV at 2.5kHz, both laboratories agreed to better than 1 part in 106. [Copyright &y& Elsevier]
