基于 Wince6.0 USBTMC 协议的研究与实现

摘要

USB 总线技术是目前测试测量类仪器主要的通信方式之一，USBTMC 协议是实现与仪器 USB 通信的唯一行业标准。本文分析了USBTMC 协议，并介绍了在 wince6.0系统中，结合 USB Function 特点实现 USBTMC 协议。实现了 USBTMC 协议的 USB 设备，可以与装有 VISA驱动的主机直接通信。 USBTMC 协议的实现对于与仪器进行信息交互有着重要的现实意义。%The USB is one of the most important communication in test and meansurement instrument,and USBTMC is the only professional standard that which communicates with instrument through USB. This dissertation analyses USBTMC protocol,and introduces the implementation of USBTMC based on USB Function of Wince6.0.The USB device with USBTMC protocol can directly communicate with host which installed drive of VISA. The implementation of USBTMC protocol has a practical significance to communicate with instrument.
