【正文】 tion.Ⅱ.Recent development results development of digital instrumentsIn recent years, as DSP(digital signal processing)technology, the rapid development of a variety of outstanding performance DSP integrated chips are emerging, digital instruments to get a new example, digital oscilloscope, digital modulation devices, digital function generator, arbitrary waveform generators, digital frequency counter and many other Domain Analyzer successful researchModulation Domain testing techniques in the frequency domain and frequency domain has been developed very mature late 20th century the emergence of a new type of measurement Test technologies that known as the “three field” testing domain test is to measure the input signal varies over time the frequency value, the displayed graphical representation of the signal generated by the modulation domain, the frequency value of the signal versus Domain testing technology is an emerging technology very important and difficult and very large test techniques, depending on the science and technology and electronic equipment rapid method is very suitable for measuring the timing signal, phase or frequencycoded signal is coded Domain TestingTechnology Surgery appears bound to numerous test problems and make new have proved that modulation domain analysis techniques, in an increasingly more applications bee an indispensable testing technology, especially in the field of military electronic test more of its bus technology has made significant progressVXI bus technology is the twentieth century the emergence of a new bus first appeared in the United States, used in the United States Air Military electronic measuring and GPIB bus to the VME bus are bined to form a new standard for modular instrumentation platform that can meet the needs of future instrumentation, electronic measurement instruments and systems to make step into a new period of bus is a new industry standard interface bus 121 is a pletely open, multivendor equipment to adapt products(modules, plugin)industry introduction of this standard there are three reasons: First, to adapt to technical requirements of the development, the second is the lack of multivendor instrument connectivity, three is the military39。Intelligent。macro grasp of electronic measurement technology future DDS technology as an example of modern electronic measurement field the new 。參考英文文獻(xiàn)The Development and Future of Electronic MeasurementTechnology Abstract—This paper describes the electronic measurement on the importance of the development of modern science and technology。目前與國外相比雖然還有些差距,但已經(jīng)基本改變過去跟著國外走的狀況。為了滿足這些改變的用戶需求,我國電子儀器工程師不斷地在原有電子測量技術(shù)及儀器水平的基礎(chǔ)上改革創(chuàng)新,趕追世界先進(jìn)水平,使得國產(chǎn)電子測量儀器向以計算機(jī)為基礎(chǔ)的功能越來越多,處理信息量越來越大,應(yīng)用領(lǐng)域越來越廣泛的現(xiàn)代電子測量儀器方向發(fā)展。但國產(chǎn)電子測量儀器在發(fā)展過程中還存在一些問題,在對其發(fā)展現(xiàn)狀進(jìn)行分析基礎(chǔ)上,指出了當(dāng)前我國電子測量儀器發(fā)展的機(jī)遇與挑戰(zhàn)。虛擬儀器是指以通用計算機(jī)作為核心的硬件平臺,配以相應(yīng)測試功能的硬件作為信號輸入/輸出接口,利用儀器軟件開發(fā)平臺在計算機(jī)的屏幕上虛擬出儀器的面板和相應(yīng)的功能,通過鼠標(biāo)或鍵盤操作的儀器。自動測試系統(tǒng)的組成包括控制器、程控儀器設(shè)備、總線與接口、測試軟件、被測對象5部分。(3)以通用計算機(jī)為核心,以國際上標(biāo)準(zhǔn)化的儀器接口總線為基礎(chǔ),由可程控的通用電子儀器構(gòu)成的現(xiàn)代自動測試系統(tǒng)。個人儀器系統(tǒng)將若干儀器的測試功能模塊并聯(lián)接入個人計算機(jī)的內(nèi)部總線,借助于測試軟件,各儀器模塊與計算機(jī)靈活地結(jié)合起來,實(shí)現(xiàn)計算機(jī)輔助測試、程控操作、數(shù)據(jù)采集和運(yùn)算處理,以及多種方式輸出測試結(jié)果。它的硬件組成通常包括微處理器與存儲器、鍵盤開關(guān)與顯示輸出、測試功能模塊或測試信號源、總線與標(biāo)準(zhǔn)接口等部分。它主要有以下幾種類型:(1)以通用微處理器為核心構(gòu)成的智能化電子儀器。傳統(tǒng)儀器很難滿足這些要求,這就迫使儀器朝著數(shù)字化、智能化、多功能、小型化、模塊化、虛擬化、標(biāo)準(zhǔn)化和開放型方向發(fā)展,隨著技術(shù)進(jìn)步和應(yīng)用領(lǐng)域的擴(kuò)大,這種演進(jìn)的趨勢也在明顯加強(qiáng)。四、電子測量儀器發(fā)展趨勢隨著科學(xué)技術(shù)和工業(yè)生產(chǎn)的發(fā)展,測量范圍日益擴(kuò)大,測量任務(wù)越來越復(fù)雜,測量工作量隨之加大,對測量精度和速度的要求也越來越高。目前,雖然國產(chǎn)電子測量儀器發(fā)展面臨著前所未有的機(jī)遇,但是由于多種原因,使得在這一行業(yè)發(fā)展過程中還存在著許許多多的挑戰(zhàn)。數(shù)字電視、新一代移動通信和下一代互聯(lián)網(wǎng)等新興產(chǎn)業(yè)、新的生產(chǎn)工藝和技術(shù)要求也為儀器發(fā)展創(chuàng)造了新的發(fā)展機(jī)遇。三、國產(chǎn)電子測量儀器發(fā)展的機(jī)遇隨著科學(xué)技術(shù)的不斷發(fā)展,新產(chǎn)品新技術(shù)日新月異,對電子測量儀器提出很多新需求,由于測量儀器的先導(dǎo)作用,所有電子技術(shù)的應(yīng)用熱點(diǎn)都會成為測量測試技術(shù)的生長點(diǎn),國內(nèi)儀器企業(yè)研制并成功向市場推出了大量新技術(shù)、新型儀器產(chǎn)品,適應(yīng)市場需要。(6)數(shù)字化儀器迅速發(fā)展。通信產(chǎn)業(yè)的發(fā)展十分迅速,為適應(yīng)通信產(chǎn)業(yè)的發(fā)展,我國加快發(fā)展通信電子測量儀器。近幾年,我們十分重視電子儀
