Abstract :
The principle of digitally synthesised AC voltage standards is well established. This paper describes a new AC voltage standard which uses a traceable DC voltage standard as an input and produces an AC output at an equivalent r.m.s. voltage to 1 ppm uncertainty. The system works using digital synthesis with a so called 1-bit digital to analogue convertor (DAC).
