This paper presents a stable millimeter-wave power monitoring system for ECRH on EAST tokamak. The real-time power monitoring was realized based on power monitor miter bends. The “Exchange”method was proposed to monitor the reflection power for RF protection. A cRIO-based signal process unit was designed, it is robust and has the response time of 1 μs. The power monitoring system was tested and the experimental results were discussed.
