Equipment based on a measurement of the noise produced by cathodes in vacuum devices, and designed for the diagnostics of thermionic cathodes under mass production conditions, is developed. Problems of automation and noise immunity to reduce the diagnostics time are solved. Software for controlling the measurement conditions, for investigating the noise characteristics, and for obtaining informative noise parameters is developed.
