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.

電子書-RTL Design Style Guide for Verilog HDL540頁A FF having a fixed input value is generated from the description in the upper portion of Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input, and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at the power supply, since the typical value ’1’ is output following the rise of the START signal. When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementing a scan design and converting to a scan FF, the scan may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that the clock signal is input to the clock pin of the FF. Other than the sample shown in Example 2-21, there are situations where for certain control signals, those that had been switched due to the conditions of an external input will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a fixed value is input from an upper level, the input value of the FF may also end up being fixed as the result of optimization with logic synthesis tools. In a situation like this, while perhaps difficult to completely eliminate, the problem should be avoided as much as possible.

天線是作無線電波的發(fā)射或接收用的一種 金屬裝置。無線電通信、廣播、電視、雷達(dá)、導(dǎo)航、電子對抗、遙感、射電天文等工程系統(tǒng),凡是利用電磁波來傳遞信息的,都依靠天線來進(jìn)行工作。此外,在用電磁波傳送能量方面,非信號的能量輻射也需要天線。一般天線都具有可逆性,即同一副天線既可用作發(fā)射天線,也可用作接收天線。同一天線作為發(fā)射或接收的基本特性參數(shù)是相同的。這就是天線的互易定理。射頻天線設(shè)計(jì)TOP2.2 微帶貼片天線微帶貼片天線是由 貼在帶有金屬地板 的介質(zhì)基片上的輻射貼片導(dǎo)體所構(gòu)成的 如圖3所示,根據(jù)天線輻射特性的需要,可以設(shè)計(jì)貼片導(dǎo)體為各種形狀,通常貼片天線的輻射導(dǎo)體 與金屬地板距離為幾十分之一波長,假設(shè)輻射電場沿導(dǎo)體的橫向與縱向兩個(gè)方向沒有變化,僅沿約為半波長(Ag/2)的導(dǎo)體長度方向變化.則微帶貼片天線的輻射基本上是由貼片導(dǎo)體 開路邊沿的邊緣場 引起的,輻射方向基本確定,因此,一般適用于通訊方向變化不大的 RFID應(yīng)用系統(tǒng)中,為了提高天線的性能并考慮其通訊方向性問題,人們還提出了各種不同的微帶縫隙天線,如文獻(xiàn)[5,6]設(shè)計(jì)了一種工作在 24 GHz的單縫隙天線和 5.9 GHz的雙縫隙天線,其輻射波為線極化波;文獻(xiàn)[7,81開發(fā)了一種圓極化縫隙耦合貼片天線,它是可以采用左旋圓極化和右旋圓極化來對二進(jìn)制數(shù)據(jù)中的"R"進(jìn)行編碼.2.3偶極子天線在遠(yuǎn)距離耦合的 RFID應(yīng)用系統(tǒng)中,最常用的是偶極子天線(又稱對稱振子天線).偶極子天線及其演化形式如圖4所示,其中偶極子天線由兩段同樣粗細(xì)和等長的直導(dǎo)線排成一條直線構(gòu)成,信號從中間的兩個(gè)端點(diǎn)饋入,在偶極子的兩臂上將產(chǎn)生一定的電流分布,這種電流分布就在天線周圍空間激發(fā)起電磁場利用麥克斯韋方程就可以求出其輻射場方程:
