<delect id="i6scc"></delect> 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.

超聲波換能器作為一種實(shí)用的檢測手段，能實(shí)現(xiàn)聲波所攜帶的信息和電能之間轉(zhuǎn)換。它的性能優(yōu)良，價(jià)格低廉，操作方便，易于調(diào)試，因此在工農(nóng)業(yè)生產(chǎn)中發(fā)揮著重要的作用。但目前換能器驅(qū)動(dòng)電路的發(fā)射頻率多為40 kHz，本文針對(duì)1 MHz的超聲波換能器電路進(jìn)行了設(shè)計(jì)，主要介紹了它的發(fā)射驅(qū)動(dòng)電路和接收驅(qū)動(dòng)電路的設(shè)計(jì)方案，并對(duì)它們的功能進(jìn)行了詳細(xì)地說明。最后搭建實(shí)驗(yàn)平臺(tái)，并對(duì)電路的輸入、輸出模塊進(jìn)行了測試。實(shí)驗(yàn)結(jié)果表明，換能器電路運(yùn)行良好，可以為超聲波高精度測量領(lǐng)域的應(yīng)用提供參考。As a practical means of detection, ultrasonic transducer can realize the conversion between theinformation carried by sound wave and electric energy.It has the advantages of excellent performance,low cost, convenient operation and debugging, so plays an important role in industrial and agriculturalproduction.However, the transmitting frequency of the driving circuit for most transducer is 40 kHz.Thecircuit of 1 MHz ultrasonic transducer is designed In this paper. It mainly introduces the emissive drivingcircuit and the receiving circuit design and the detailed function of them. Finally, the experimentalplatform is built, and the circuit of input and output were tested. Experiments show that the transducer＇ s...

VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.
