There is an unprecedented enthusiasm for radio frequency identification (RFID) technologies today. RFID is based on the exchange of information carried by electromagnetic waves between a label, or tag, and a reader. This technology is currently in full economic expansion, which has manifested itself in widely backed research activities, some of which will be examined in this book.

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level. Additional Notices Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC This product complies with the WEEE Directive (2002/96/EC) marking requirement. The affixed product label (see below) indicates that you must not discard this electrical/electronic product in domestic household waste. Product Category: With reference to the equipment types in the WEEE directive Annex 1, this product is classified as a "Monitoring and Control instrumentation" product. Do not dispose in domestic household waste. To return unwanted products, contact your local Agilent office, or see www.agilent.com/environment/product for more information. Agilent 34138A Test Lead Set The Agilent 34401A is compatible with the Agilent 34138A Test Lead Set described below.

第一步：新建PCB工程文件 并向工程文件里添加PCB文件和原理图文件 第二步：元件库、封装库设计 部分元器件厂商或者经销商不提供元件库和封装库，只给了元器件尺寸图，所以需要自行设计元件 库文件或是封装库文件 元件库设计： 新建 .SchLib 文件：File -> New -> Library -> Schematic Library 使用Place下拉菜单或使用快捷工具栏放置图形，引脚等，记得保存！ 封装库的设计 新建.PcbLib文件：File -> New -> Library -> PCB Library 使用Place下拉菜单或使用快捷工具栏，画线，放置孔位，记得保存！第三步：原理图的绘制 新建.SchDoc文件 ：File -> New -> Schematic 添加元器件库和封装库 在软件底部菜单栏System中勾选Libraries，打开侧面工具栏 在侧面工具栏中点击“Libraries...” -> “Add Library”找到自己保存的库文件并添加 添加各元器件 可直接从侧面工具栏中选择元器件拖入原理图中，在拖动过程中按Tab键修改元器件信息 添加网络标识Place -> Net label 快捷键（PN） 确定各元器件封装 打开封装管理器Tools -> Footprint Manager 快捷键（TG） 可挨个修改、检查各元器件封装
