Abstract
In order to test the function and performance of the electronic control unit of lunar-based extreme ultraviolet camera,a test system based on FPGA is designed.This system adopts FPGA as processing and control core.The system uses the communication with the computer through USB bus.And it can analyse remote data and image data which are collected by external interface of electronic control unit.Therefore,this system can complete the test of each function and each performance of the electronic unit.The result of the testing experiment of lunar-based extreme ultraviolet camera control unit and test system shows that test method of the system is accurate,and the test results are correct and effective.Because it has been fully used during the development of extreme ultraviolet camera,this test system played a great important role on the smooth degree of designing process in the program,which has the features of practical,efficient and portable.
