We experimentally and numerically study one-dimensional, temporally forced wave patterns and analyze the transition from unforced traveling waves to forced standing waves when a source defect is present in the system. Our control parameter is the amplitude of the forcing. Two scenarios are identified, depending on the distance from the bifurcation threshold of traveling waves.
