Electron tube mounted on terminal base for investigating the design and operation of a cathode ray tube. The electron beam can be deflected by an electric field produced by the deflection plates integrated into the tube, and by a magnetic field from three external coils mounted on a ring. A Wehnelt cylinder is used to focus the beam. A gas filling and fluorescent screen make it possible to observe the beam in the tube. A continuously adjustable saw-tooth generator can be used to analyze and visualize time dependent processes. The device comes with a socket and printed wiring scheme.
