【摘要】The data transfer rate of UM-BUS can reach 200 Mbps/lane,and the effective bandwidth can reach 149. 5 MB/s at 8 lanes.The channel bandwidth between data acquisition terminal and PC must meet the above requirement.The USB3. 0’s theo-retical transmission rate can reach 5 Gbps,which meets requirement of UM-BUS test system.the design and application of USB3. 0 in the bus test system was put porward.The experimental result show that the USB3. 0 can ensure data transmission running at 180 MB/s.Data’s monitor with no filter and fault injection are both the bus test system’s important functions,the performance of USB3. 0 application lays the foundation of these functions realization.%UM-BUS总线单通道最高通信速率为200 Mbps，采用8通道并发传输时，总线有效带宽可达149．5 MB／s，其测试系统需要在采集终端与PC机之间建立不低于此带宽的通信通道，USB3．0理论传输速率可达5 Gbps，可满足UM-BUS总线测试系统的传输需求，由此设计实现UM-BUS总线测试系统的USB3．0应用方案。实验测试结果表明，该方案实际传输速度可达180 MB／s，为实现UM-BUS测试系统的无过滤监听和故障注入等功能打下了基础。 【总页数】7页(514-519,538)
