A cathode-ray oscillograph equipment embodying a high-voltage, gas-filled, sealed-glass oscillograph tube

A description is given of an oscillograph equipment for high recording speeds incorporating a recently developed type of high-voltage, gas-filled, cold-cathode, sealed-glass oscillograph tube, and therefore requiring no pumps. Constructional details and characteristics of the tubes and all accompanying accessories necessary for the operation of the oscillograph, with their arrangement in a common housing, are given. The means of beam control are described; also the mode of action of electromagnetic and of electrostatic deflection circuits for cyclic and single-sweep phenomena, and for controlled and uncontrolled events, is explained. Specimen oscillograms illustrating each case are given. As far as possible, the more recent features only of cathode-ray oscillograph technique are emphasized.
