Research of the Distributed Digital Delay Pulse Generator in the Prototype of Laser System
激光打靶装置中的集散式数字同步系统的研究

A distributed digital delay pulse generator is described,which combines skillfully the analog delay circuit and the digital delay circuit. It includes a lot of local control units and a remote control unit based a computer. The system incorporates the local control, the remote control and the centralized remote control of the digital delay pulse generator into the body. RS-422 bus is used for the communication between the remote control unit and the local control units.
