【摘要】：高速數(shù)據(jù)發(fā)生器作為現(xiàn)代數(shù)據(jù)域測(cè)試的重要信號(hào)源,已廣泛應(yīng)用于數(shù)字通信系統(tǒng)、數(shù)字集成電路等領(lǐng)域。在系統(tǒng)故障診斷或調(diào)試以及對(duì)半導(dǎo)體器件進(jìn)行測(cè)試等場合,可用于提供激勵(lì)信號(hào),因此高速數(shù)據(jù)發(fā)生器已成為現(xiàn)代數(shù)據(jù)域測(cè)試中不可或缺的一種工具。作為高速數(shù)據(jù)發(fā)生器的重要組成部分,模擬通道板決定了輸出信號(hào)的許多參數(shù),如高低電平、幅度、轉(zhuǎn)換時(shí)間等。高速數(shù)據(jù)發(fā)生器的通道板模塊如何完成高頻脈沖信號(hào)的調(diào)理,是研發(fā)高性能數(shù)據(jù)發(fā)生器的難點(diǎn)。高頻脈沖信號(hào)包含高次諧波,使得信號(hào)具有較高的帶寬,這對(duì)通道調(diào)理電路的設(shè)計(jì)是一個(gè)很大的考驗(yàn),如果設(shè)計(jì)不當(dāng),會(huì)限制信號(hào)數(shù)據(jù)率的擴(kuò)展。對(duì)于高頻脈沖信號(hào)的直流偏置也是通道調(diào)理電路的一個(gè)難點(diǎn),直流偏置器所適用的頻率范圍、插損等指標(biāo)都會(huì)對(duì)輸出信號(hào)的波形造成很大的影響,本文將會(huì)對(duì)這些問題進(jìn)行具體闡述�；诟咚贁�(shù)據(jù)發(fā)生器在現(xiàn)代測(cè)試領(lǐng)域的重要性,本文主要針對(duì)高頻脈沖信號(hào)調(diào)理技術(shù)展開研究,并將研究結(jié)論應(yīng)用到數(shù)據(jù)發(fā)生器(Data Generator,簡稱DG)通道的設(shè)計(jì)當(dāng)中。線性調(diào)理技術(shù)和非線性調(diào)理技術(shù)是信號(hào)調(diào)理技術(shù)的兩個(gè)重要分支,本文根據(jù)兩種調(diào)理技術(shù)分別進(jìn)行相應(yīng)的電路設(shè)計(jì),通過對(duì)兩種實(shí)驗(yàn)電路結(jié)果的分析確定出兩種調(diào)理技術(shù)的優(yōu)點(diǎn)和缺點(diǎn),并確定出適合用于完成本項(xiàng)目設(shè)計(jì)要求的調(diào)理技術(shù)。本論文的主要內(nèi)容包括：1、結(jié)合國內(nèi)外發(fā)展現(xiàn)狀,針對(duì)本項(xiàng)目的具體要求,結(jié)合高頻脈沖信號(hào)的特點(diǎn)來分析通道調(diào)理技術(shù)的難點(diǎn)。2、對(duì)線性調(diào)理技術(shù)展開論述,并對(duì)相關(guān)技術(shù)進(jìn)行研究。根據(jù)研究結(jié)果進(jìn)行相應(yīng)的電路設(shè)計(jì),并根據(jù)實(shí)驗(yàn)結(jié)果對(duì)線性調(diào)理技術(shù)進(jìn)行總結(jié),分析出線性調(diào)理技術(shù)的優(yōu)點(diǎn)和缺點(diǎn)以及所適用的范圍。3、對(duì)非線性調(diào)理技術(shù)展開論述,并對(duì)相關(guān)技術(shù)進(jìn)行研究。根據(jù)研究結(jié)果進(jìn)行相應(yīng)的電路設(shè)計(jì),并對(duì)非線性調(diào)理技術(shù)進(jìn)行總結(jié),然后分析出非線性調(diào)理技術(shù)所適用的范圍。最后給出線性調(diào)理技術(shù)與非線性調(diào)理技術(shù)的區(qū)別。
[Abstract]:As an important signal source in modern data domain testing, high speed data generator has been widely used in digital communication systems, digital integrated circuits and other fields. High speed data generators have become an indispensable tool in modern data domain testing because they can be used to provide excitation signals in fault diagnosis or debugging of systems and testing of semiconductor devices. As an important part of high speed data generator, analog channel board determines many parameters of output signal, such as high and low level, amplitude, conversion time and so on. How to adjust the high frequency pulse signal in the channel board module of the high speed data generator is a difficult point in the research and development of the high performance data generator. The high frequency pulse signal contains high order harmonics, which makes the signal have higher bandwidth, which is a great test for the design of channel conditioning circuit. If the design is not proper, the expansion of signal data rate will be limited. The DC bias of the high frequency pulse signal is also a difficult point in the channel conditioning circuit. The frequency range and the insertion loss of the DC offset will have a great influence on the waveform of the output signal. This article will carry on the concrete elaboration to these questions. Based on the importance of high-speed data generator in the field of modern testing, this paper mainly focuses on the high-frequency pulse signal conditioning technology, and applies the research conclusion to the design of data generator (DG) channel. Linear conditioning technology and nonlinear conditioning technology are two important branches of signal conditioning technology. By analyzing the results of two kinds of experimental circuits, the advantages and disadvantages of the two conditioning techniques are determined, and the conditioning techniques suitable for the design requirements of this project are determined. The main contents of this paper include: 1. According to the development situation at home and abroad, according to the specific requirements of this project, combined with the characteristics of high frequency pulse signal to analyze the difficult point of channel conditioning technology, to discuss the linear conditioning technology. And the related technology is studied. According to the results of the research, the corresponding circuit design is carried out, and the linear conditioning technology is summarized according to the experimental results. The advantages and disadvantages of the linear conditioning technology and the applicable range. 3 are analyzed, and the nonlinear conditioning technology is discussed. And the related technology is studied. According to the results of the research, the corresponding circuit design is carried out, and the nonlinear conditioning technology is summarized, and then the scope of application of the nonlinear conditioning technology is analyzed. Finally, the difference between linear conditioning and nonlinear conditioning is given.
