Application of CPLD to TWT Transmitter

This paper introduces the application of CPLD in monitoring and controlling system of TWT transmitter. The system has both advantages of real-time in hardware and programming in software. The use of EDA tool decrease software development time. The paper analyzes the sources of disturbances of TWT transmitter. It introduces EMC measures used in hardware and software designs to improve the system's EMC. These measures prove highly effective for improvement of system reliability. The system can accomplish logic control, fault detection, time-sequence control and communication between CPLD and RS232, which is proved to be good in use.
