Aim: The JRP will bring about a fundamental change to the way in which the volt is disseminated in the SI for AC waveforms. Direct traceability to the quantum standard of voltage, based on the Josephson effect will be provided for sampled electrical measurements. Thus there will no longer be a distinction between so-called DC and AC measurements for the volt and a direct link to the SI for digital measurement systems will be provided at operating frequencies of up to 10 MHz.
