Abstract :
This paper reports recent developments of the VSL high frequency AC-DC transfer facilities. For the calculable HF AC-DC standard, figures are given on the long-term stability and consistency between other users. Furthermore, improvements of the measurement set-up (frequency and voltage range and stability) and the RF voltage control are discussed.
