It is shown that the external behavior of a cell of two interacting Josephson junctions in the vicinity of phase locking is quantitatively the same as that of a single equivalent resistively shunted junction operated at the difference frequency of the two interacting junctions, as predicted by perturbation theory. Steps of constant voltage difference closely obeying the familiar Bessel dependence are observed when an external current with a frequency equal to the difference of the two Josephson frequencies is applied.
