Abstract :
Techniques at present in use for the recording of single-shot phenomena by cathode-ray oscillographs are reviewed. Cathode-ray tubes are discussed, with particular attention to the conflicting requirements of high writing speed, wide bandwidth and high sensitivity. These requirements can be met to a large extent by the use of very small spot size and travelling-wave techniques. An account is given also of associated circuits including high-speed time-bases, amplifiers and calibration equipment.
