易于操作的快速自动测试系统带有USB接口。在测试产品应用中，使用480Mbps的USB数据传输速率可缩短测试时间。在产品研发时，USB的易用性使工程师能够快速搭建一个测试系统，并很快得到其频率或温度特性。本文给出了在自动测试中使用USB的优点、用USB实现与测试测量设备通讯的可能方法及一些USB的设计指南。 -Express easy-to-use automatic test system with USB interface. Products in the test applications, the use of 480Mbps data transfer rate of USB test time can be shortened. Product R &　D at the time, USB' s ease of use so that engineers can quickly build a test system, and soon its frequency or temperature characteristics. In this paper, the use of automated testing at the advantages of USB, the USB implementation and test and measurement equipment, communication method and some possible USB Design Guide.
