A Study On Ultra-Lower Frequency Phase Source System And Its Key Technology

With the application and development of computer technology there has been plenty of room for measuring instruments to develop and improve. In view of the fact that ultra-low frequency phase sources could not meet the needs of test and verification for instruments in our defense industry at the moment, an A/D-D/A technology was suggested in this paper to realize the program about ultra-low frequency phase, and an ultra-low frequency phase source system has been developed by means of computer and arbitrary wave-form generator.The key technology of the system was discussed and its composition and working-principles were described. With these studies, it is desired to acquire some methods and experiences in utilizing relatively advanced or widely employed instruments, and to explore a new aspect of designing approaches to the research and development of domestic equipments with ultra-low frequency parameters.
