To solve the test problems of launch vehicles ground test equipment such as long calibration cycle,com-plex and various test methods, a timing simulation test system is designed based on SOPC and USB 3. 0 ( CYUSB3014) for launch vehicle. 64-channels of timing timing sequence and timing bunchs can be produced to test launch vehicles ground test equipment with different test requirements. This system has advantages easy to ap-proach,versatility,high precision and a large number of channels which can improve the test efficiency.
