Abstract :
In this paper, a high-power microwave amplifier system is discussed with main emphasis on the method of control and detection, which can protect the core component of the amplifier system - traveling wave tubes (TWT) effectively, detect the real-time input and output power of the amplifier system and caculate the data which detected from the amplifier. In this system a human machine interface (HMI) is adopted as the master platform and a programmable logic controller (PLC) is adopted as the slave to make real-time contral and protection. The software structure is modulized. A friendly interface for automatical test of TWT is provided in this system.
