Abstract :
A new 4-terminal-pair bridge, capable of a relative uncertainty of 1 in 10/sup 9/, has been constructed at NIST by converting a 2-terminal pair bridge. The conversion requires only addition of components which are easily removed if 2-pair measurements are to be made. The design and testing of this bridge are described.
