<p>An optical device under test - DUT - (10) having m inputs, with m = 1, 2, 3, ..., M, and n outputs, with n = 1, 2, 3, ..., N, is tested by applying a plurality of different characteristic stimulus signals (Si) to at least one of the m inputs. A response signal (Ri) is received at at least one of the n outputs, and a property of the DUT (10) can be determined or verified by evaluating the received response signal in conjunction with at least one of the applied stimulus signals (Si) or at least an indication thereof. The plurality of different characteristic stimulus signals (Si) are provided in a way allowing tracing each respectively applied stimulus signal (Si) in each received response signal (Ri) - if present or beyond a detectability threshold. <IMAGE></p> |
