【摘要】：高速數(shù)據(jù)發(fā)生器作為現(xiàn)代數(shù)據(jù)域測試的重要信號源,已廣泛應用于數(shù)字通信系統(tǒng)、數(shù)字集成電路等領域。在系統(tǒng)故障診斷或調(diào)試以及對半導體器件進行測試等場合,可用于提供激勵信號,因此高速數(shù)據(jù)發(fā)生器已成為現(xiàn)代數(shù)據(jù)域測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的許多參數(shù),如高低電平、幅度、轉換時間等。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的調(diào)理,是研發(fā)高性能數(shù)據(jù)發(fā)生器的難點。高頻脈沖信號包含高次諧波,使得信號具有較高的帶寬,這對通道調(diào)理電路的設計是一個很大的考驗,如果設計不當,會限制信號數(shù)據(jù)率的擴展。對于高頻脈沖信號的直流偏置也是通道調(diào)理電路的一個難點,直流偏置器所適用的頻率范圍、插損等指標都會對輸出信號的波形造成很大的影響,本文將會對這些問題進行具體闡述�；诟咚贁�(shù)據(jù)發(fā)生器在現(xiàn)代測試領域的重要性,本文主要針對高頻脈沖信號調(diào)理技術展開研究,并將研究結論應用到數(shù)據(jù)發(fā)生器(Data Generator,簡稱DG)通道的設計當中。線性調(diào)理技術和非線性調(diào)理技術是信號調(diào)理技術的兩個重要分支,本文根據(jù)兩種調(diào)理技術分別進行相應的電路設計,通過對兩種實驗電路結果的分析確定出兩種調(diào)理技術的優(yōu)點和缺點,并確定出適合用于完成本項目設計要求的調(diào)理技術。本論文的主要內(nèi)容包括：1、結合國內(nèi)外發(fā)展現(xiàn)狀,針對本項目的具體要求,結合高頻脈沖信號的特點來分析通道調(diào)理技術的難點。2、對線性調(diào)理技術展開論述,并對相關技術進行研究。根據(jù)研究結果進行相應的電路設計,并根據(jù)實驗結果對線性調(diào)理技術進行總結,分析出線性調(diào)理技術的優(yōu)點和缺點以及所適用的范圍。3、對非線性調(diào)理技術展開論述,并對相關技術進行研究。根據(jù)研究結果進行相應的電路設計,并對非線性調(diào)理技術進行總結,然后分析出非線性調(diào)理技術所適用的范圍。最后給出線性調(diào)理技術與非線性調(diào)理技術的區(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.
