BIPM, NPL and PTB comparison carried out as part of EMPIR project will be used to validate AC quantum voltage standard.
Thanks to the collaboration of BIPM in the project, a pioneering intercomparison of AC quantum voltage standards has been arranged and will start this year. The BIPM, NPL and PTB comparison will be used to validate the AC quantum voltage standard design. The design is based on the combination of a PJVS and ultra-stable synthesiser so different waveform can be compared. This will serve as a basis for future worldwide comparisons of AC quantum voltage standards.
