Josephson junctions act as active elements in superconducting electronics. The behavior of this nonlinear element is characterized by the relation between current and the quantum mechanical phase-difference. For an accurate device modeling detailed knowledge about this relation is necessary. To obtain detailed information, a method for direct measurement of the current-phase relation of different types of Josephson junctions was accomplished.
