In this presentation, we consider two mechanisms, of force and parametric types, for resonance oscillation excitations (actuations) in an autonomous high-Q oscillatory circuit coupled with Josephson junction, as well as the oscillation phase locking under an external microwave signal. Similarity and difference in the phenomena and the phenomenon manifestation in IV-curve of the Josephson junction are analyzed and discussed. The developed analytic theory is compared with results of numerical simulation.
