【摘要】：LXI总线作为下一代测试总线，使用开放的以太网技术作为通信手段，充分利用当前和未来以太网的能力。本课题主要是以频谱分析仪为载体研究LXI-C接口的实现，并提出了一种基于ARM11处理器和Linux操作系统的LXI频谱分析仪实现方案。文章先介绍自动测试系统及总线技术的发展概况，从而引出新一代的测试总线LXI总线。在详细论述LXI总线特点与优势后，并且提出了本课题的研究任务。论文接着介绍频谱分析技术和LXI接口中的关键技术，并提出本课题的实施方案。本文按照前面提出的硬件系统实现方案详细介绍了频谱分析仪硬件系统的设计过程，包括处理平台、LAN接口和模拟信号调理通道等。按照软件系统方案，软件主要分为两个部分：软件平台的搭建及仪器功能的实现和LXI接口功能的实现。前者包括Linux平台移植、设备驱动程序编写和FFT频谱分析算法实现等。后者包括基于VXI-11的仪器发现与识别、LAN配置、仪器驱动和Web服务器等的实现。论文最后总结了本课题的工作，提出下一步的完善设想。 LXI频谱分析仪的研究为后续LXI仪器的研究提供了参考方案和实现技术，为推动LXI总线技术的发展做了一定的贡献。
[Abstract]:As the next generation test bus, LXI bus uses open Ethernet technology as the means of communication. Make full use of the current and future Ethernet capabilities. This topic is mainly based on the spectrum analyzer as the carrier to study the implementation of the LXI-C interface. An implementation scheme of LXI spectrum analyzer based on ARM11 processor and Linux operating system is proposed. This paper first introduces the development of automatic test system and bus technology, and then leads to a new generation of test bus LXI bus. After discussing the characteristics and advantages of LXI bus in detail. Then the paper introduces the spectrum analysis technology and the key technology of LXI interface, and puts forward the implementation scheme of this subject. In this paper, the hardware system design process of spectrum analyzer is introduced in detail according to the hardware system implementation scheme, including processing platform LAN interface and analog signal conditioning channel, etc. According to the software system scheme. The software is mainly divided into two parts: the construction of the software platform, the realization of the instrument function and the realization of the LXI interface function. The former includes the transplantation of the Linux platform. Device driver programming and FFT spectrum analysis algorithm are implemented. The latter includes VXI-11 based instrument discovery and identification configuration. The realization of instrument driver and Web server. Finally, this paper summarizes the work of this subject, and puts forward the next perfect assumption. The study of LXI spectrum analyzer provides a reference scheme and implementation technology for the subsequent research of LXI instruments, and makes a certain contribution to the development of LXI bus technology.
