| Abstract: | A synchronous phase signal source based on synchronous set direct digital synthesis（DDS）technology as a various frequency and strict in-phase reference signal source of system was designed for low level phase and magnitude stabilization system of HIRFL. Taking FPGA as the kernel,the functional modules was designed with the VHDL language,which simplified the design process. It is easy to upgrade. The validity of system was verified by the circuit design,module simulation and test on spot. Performance test results show that the system has the advantages of high reliability,high precision,high stability and wide frequency range,and is easy to control. |
