Characterization of low-voltage AC-DC transfer standards between 10 Hz and 1 MHz at LNE

This paper describes the procedure recently introduced at LNE to calibrate low-voltage AC-DC transfer reference standards from 10 Hz to 1 MHz. Especially, a set of micro-potentiometers was developed in order to take into account the voltage level dependence of the standards during the step-down procedure. First measurement results are presented.
