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. Test Lead Ratings Test Leads - 1000V, 15A Fine Tip Probe Attachments - 300V, 3A Mini Grabber Attachment - 300V, 3A SMT Grabber Attachments - 300V, 3A Operation The Fine Tip, Mini Grabber, and SMT Grabber attachments plug onto the probe end of the Test Leads. Maintenance If any portion of the Test Lead Set is worn or damaged, do not use. Replace with a new Agilent 3413

好吧，電路很簡單，可是元件值如何選？射頻器件差一點就差很多，是不是一定要用專用的射頻元件？做為常溫測試來說，普通器件就可以滿足，當然，如果要考慮溫度、諧波、靈敏度等，電感還是選用高Q的，電容選擇COG材質的。看看PA元件如何選，AN435里寫得很清楚。不想看原理的可以直接參考其值：按以上參考值出17-19dBm是可以的，但是要滿打滿的出到20dBm，或者大于20dBm則需要根據板子微調部分元件，在你不知道如果調試時，可以小范圍調整一下CM以及天線開關后面的低通濾波器，如果還是不行，那就調電感吧。不想深究的可以跳過本節了，下面是AN435里對于PA匹配的原理性說明，感興趣的可以繼續往下面看，其實Sl4432的硬件手冊里說得是很全的，多看手冊可以學到很多。Sl4432內部的PA并非傳統的A，B，C類放大器，也不是D類，而是E類放大器，其實就是一個開關而已。下圖是AN435里一個開關類射頻放大器的結構圖。這個放大器理解起來很容易，比傳統ABC類放大器容易多了。其中Lchoke為上拉電感，與三極管C極的電阻是一樣的作用，在S0開關時，會給Cshunt充電，經過CO和LO組成的帶通濾器器，濾除開關過程中產生的雜波及諧波，再經過Lx就可以得到一個正弦波。這類放大器只是提供一個方波，再通過LC選頻。
