An improved wavelength division multiplexing device is disclosed. According to the invention, adaptation to a video frequency response sought is in each case carried out automatically by means of corresponding shifting of the vision carrier relative to the IF total transmission curve. When the plate electrodes need to be removed, the electrode loading compartment can be moved translationally with respect to the housing to define a gap therebetween. A determination is made as to whether the graphical program meets the performance criteria.
