Comparisons of the 10 V Josephson array voltage standard (JAVS) of the Bure
au 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), Bor (a) ov
er circle s, Sweden, in January 1998, Although the results agree within an
overall uncertainty of less than one part in 10(9), a small but interesting
dependence on microwave power was observed in the de output of one array.
