The large-screen oscilloscope here described is characterized by versatility and convenience of operation. Colored pictures are particularly suited for demonstration experiments. In a first part the paper discusses the general requirements to be met by such a system and a few typical applications. An ordinary color picture tube as designed for television type scanning deflection is used. To present multicolor-multichannel pictures by a fixed frequency scanning system would, however, involve very complex circuity. Thus an x-y-deflection system customary with ordinary oscilloscopes is employed. This provides, incidentally, a better contrast. In a second part of the article deflection and convergence units of the system are discussed.
