ABSTRACT
Electronic oscilloscopes are widely applied for display of form and measurement of parameters of electric signals. Traveling-wave oscilloscopes with traveling-wave cathode-ray tubes have been developed for investigation of single short electric pulses and fast nonrepetitive processes. In a traveling-wave deflecting system, the signal wave propagates along the electrodynamical deflecting system. The velocity of the wave must be close to the velocity of the electrons of the electronic beam. A simplified model of the signal path in traveling-wave cathode-ray tubes (TW CRT) for analysis of processes in transitions to traveling-wave deflecting systems is proposed, and the influence of transitions on properties of traveling-wave deflecting systems and TW CRTs is discovered. The width of the pass-band and operation speed of TW CRTs and traveling-wave oscilloscopes depend on many factors. The rise time of the transient response is minimal when wave and electron velocities are matched at higher frequency.
