Abstract

Comparisons of the 10 V Josephson array voltage standard (JAVS) of the Bureau International des Poids et Mesures (BIPM) were made at the Physikalisch-Technische Bundesansalt (PTB), Braunschweig, Germany with those of the PTB and of the Swedish National Testing and Research Institute (SP), Boras, Sweden, in January 1998. Although the results agree within an overall uncertainty of less than one part in 10⁹, a small but interesting dependence on microwave power was observed in the dc output of one array
