We implement the impedance measurement technique (IMT) for characterization of interferometer-
type superconducting qubits. In the framework of this method, the interferometer loop is inductively
coupled to a high-quality tank circuit. We show that the IMT is a powerful tool to study
a response of externally controlled two-level system to different types of excitations. Conclusive
information about qubits is obtained from the read-out of the tank properties.
