摘　　要：为了使非LXI(LAN e Xtensions for Instrumentation)接口的仪器仪表可以接入到支持LXI标准的仪器仪表系统中,并且能够同时使用SCPI(Standard Commands for Programmable Instruments,SCPI)标准可编程仪器命令对设备进行统一管理,提出一种基于嵌入式LXI代理模块的SCPI命令转换方法。通过对USB数据包流图的捕获,验证了USB主机驱动的编程是成功的,并且通过上位机发送查询和控制命令,实现了LXI接口规范以及SCPI命令与厂家自定义命令之间的转换。In order to make the non-LXI instrumentation interface instrument access to the instrumentation system of support- ing LXI standard, and simu[taneously also apply the standard programmable instruments command to manage equipment and device uniformly,a method of SCPI command conversion based on embedded LXI agent module is proposed. By means of capturing the datagram of USB, verifying the USB host-driven programming is successful. And through sending the query and control commands from the host computer,we can achieve the LXI interface specification,and implement the conversion between the SCPI commands and the manufacturers custom commands.
