摘　　要：介绍了一种基于 VXI总线的宽带网络测试仪终端控制系统的硬件和软件设计。该系统将带有读写控制的双口 RAM作为邮箱 ,利用自定协议的“邮件”与嵌入式系统通信 ,交换控制信息和响应信息。其主要设计目标是提供用户与宽带测试仪之间高速友好的接口 ,该接口已全面实现。As an excellent platform of instrument buses and automatic test systems, VXI bus is widely applied in the fields of test and instrumentation in China. This paper introduces the hardware and the software designs of a terminal control system for a wideband net tester based on VXI bus. The terminal control system uses a dual port RAM with read and write controls as a mailbox to communicate with an embedded system. Control information and response information is exchanged by mails in the format of protocol made by us. The main goal of this scheme is to provide a high speed and friendly interface between users and the wideband net tester.
