The Research And Development Of The Pulse Generator Based On SOPC

With the high speed pulse generator developed, its application is very broad. Teaching and research,industry control,the research and development of communication products and so many other field in which products need the signal generator module to realize its perfect functions. Therefore, a high speed pulse generator with a good stability, nanosecond pulse width and controllable period plays an important role in the development of electronic technology.The intention of the design is to provide the electro-optic modulator of distributed optical-fiber brillouin measurement system a driving source which consists of numerical control pulse generator system and automatic bias voltage system. The paper set down the implementation scheme with SOPC technique, based on the seriously analysis to the measurement system, and give a detailed account to the hardware circuit and software design about the high speed pulse generator along with impulsive control system and bias voltage generator along with automatic bias voltage contol system. Finally, successfully accomplish the driving source as the electro-optic modulator.
