Abstract :
The European JAWS project addresses the lack of instrumentation and knowledge for accurate and traceable measurement and generation of alternating (AC) voltage with arbitrary waveforms. The objective is to develop a standard based on a Josephson Arbitrary Waveform Synthesizer (JAWS), a precise instrument that links the generated voltage to the Josephson effect, which in turn relates the voltage to fundamental constants and a frequency. The standard aims at synthesized voltages up to 10 mV, frequencies up to 10 kHz and uncertainty smaller than 1 part in 104. This paper reports on the progress in developing the key components for JAWS
