ABSTRACT:
Detecting different spectral components of a response signal received from a device under test -DUT- in response to a stimulus signal, with a first splitter receiving the response signal and wavelength depending splitting from response signal a first partial signal and a second partial signal, a second splitter receiving the second partial signal and wavelength depending splitting there from a third partial signal, an optical detector, for receiving the first partial signal and the third partial signal and determining a corresponding optical power, and an optical shutter arranged to be moved to either let through to or block from the optical detector one of: the first partial signal and the third partial signal.
