An analysis was undertaken of the dynamic parameters of standard cells in a circuit for the direct measurement of a standard cell with a Josephson junction array voltage standard. The parameters of the models of a null detector and a standard cell were determined experimentally. It is shown that, according to these parameters, a standard cell can be measured directly with a voltage standard, with an uncertainty at the nanovolt level.
