Abstract:

A cathode ray oscilloscope assembly adapted to be connected to a circuit for conveying electrical input signals and electrical power thereto, includes a cathode ray oscilloscope tube adapted to be connected to the input circuit to establish an electron beam for illuminating the face of the tube screen, a deflection device mounted on the tube neck portion and connected electrically to the input circuit for moving selectively the beam, a rear end circuit panel fixedly connected to the tube and extending transversely to the neck portion of the tube, a plurality of side circuit panels extending forwardly from said rear panel toward the tube screen parallel to the axis of the neck portion of the tube to form an open boxlike configuration with the rear end panel for receiving the neck portion of the tube, and connectors interconnecting mechanically the adjoining marginal edges of the side panels to the rear panel and interconnecting electrically circuit elements mounted on the rear end and side panels for controlling the deflection device to selectively illuminate the tube screen in response to the input signals. The height and width of the face of the rear panel are less than the respective height and width of the screen, and the length of the entire cathode ray oscilloscope assembly is substantially the same as the length of the cathode ray tube itself. The width of the side panels is less than the corresponding dimensions of the tube screen.
