Abstract

The invention discloses a klystron testing and aging system and a corresponding method. The system comprises a signal source, a solid-state amplifier, a first directional coupler, an arc light protection waveguide, a second directional coupler, a water load, a high-voltage power supply, a rigid tube modulator, a cooling system, a titanium pump power supply, a filament power supply, a current detection circuit, a timer and a control protection module. According to the klystron testing and aging system, insulation testing, static and dynamic aging, working point parameter testing, output power,gain, bandwidth and frequency response testing and efficiency testing of the cathode modulation klystron can be achieved, the automation degree is high, unattended operation is achieved, and the tedious, time-consuming and labor-consuming testing, aging and debugging processes are simplified.

Description

technical field [0001] The invention relates to the field of radar testing, in particular to a klystron testing and aging system and a corresponding method. Background technique [0002] In the field of high-power radar transmitters, electric vacuum tubes are the key components that determine system functions, especially single-shot and multi-shot klystrons with permanent magnet focusing, which are small in size, light in weight, simple in control mode, and have significantly improved efficiency and bandwidth The product greatly reduces the operating voltage and has been widely used. In the process of debugging and using the transmitter, it is very important to accurately grasp the working parameters of the klystron. In addition, in general, electric vacuum transmitters generally have backup klystrons, and the burn-in and debugging of backup klystrons is also an important task. In order to master the working parameters of the klystron, perform aging and debugging, and simp...
