ATAPI标准资料。硬盘接口IDE（Integrated Drive Electronies）也称AT总线接口，是当前新型硬盘驱动器普遍采用的一种接口。它最早由Texan和Compaq公司提出，目的是把硬盘控制器嵌入到驱动器中。1988年10月，ANSI中的X3T9．2工作组的一个委员会开始讨论IDE的有关问题。1993年2月发表了该标准的3．1版本，使其成为了正式的ANSI标准，并赋予了一个新的名称--ATA（AT Attachment）。从概念上说，ATA与IDE具有基本相同的含义。

Learn about the design tradeoffs involved in creating Windows CE .NET operating system (OS) solutions for hardware that implements one of many nonvolatile storage technologies. Different storage technologies, such as NAND and NOR flash memory, masked ROM, and electromechanical Advanced Technology Attachment (ATA) or Integrated Drive Electronics (IDE) storage, impose design constraints and create opportunities for the software environment.

Wireless penetration has witnessed explosive growth over the last two decades. Accordingly, wireless devices have become much denser per unit area, resulting in an overcrowded usage of wireless resources. To avoid radio interferences and packet collisions, wireless stations have to exchange control messages to coordinate well. The existing wisdoms of conveying control messages could be classified into three categories: explicit, implicit, or hybrid.

A power semiconductor module is basically a power circuit of different materials assembled together using hybrid technology, such as semiconduc- tor chip Attachment, wire bonding, encapsulation, etc. The materials involved cover a wide range from insulators, conductors, and semiconduc- tors to organics and inorganics. Since these materials all behave differently under various environmental, electrical, and thermal stresses, proper selec- tion of these materials and the assembly processes are critical. In-depth knowledge of the material properties and the processing techniques is there- fore required to build a high-performance and highly reliable power module.

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.
