In this paper, the realization of an inductance scale from 1~$\mu$H to 10~Hfor frequencies ranging between 50~Hz to 20~kHz is presented. The scale isrealized directly from a series of resistance standards using a fully automatedsynchronous sampling system. A careful systematic characterization of thesystem shows that the lowest uncertainties, around 12~$\mu$H/H, are obtainedfor inductances in the range from 10~mH to 100~mH at frequencies in the kHzrange. This new measurement system which was successfully evaluated during aninternational comparison, provides a primary realization of the henry, directlytraceable to the quantum Hall effect. An additional key feature of this systemis its versatility. In addition to resistance-inductance (R-L) comparison, anykind of impedances can be compared: R-R, R-C, L-L or C-C, giving this samplingsystem a great potential of use in many laboratories around the world.
