【摘要】：高速数据发生器作为现代数据域测试的重要信号源,已广泛应用于数字通信系统、数字集成电路等领域。在系统故障诊断或调试以及对半导体器件进行测试等场合,可用于提供激励信号,因此高速数据发生器已成为现代数据域测试中不可或缺的一种工具。作为高速数据发生器的重要组成部分,模拟通道板决定了输出信号的许多参数,如高低电平、幅度、转换时间等。高速数据发生器的通道板模块如何完成高频脉冲信号的调理,是研发高性能数据发生器的难点。高频脉冲信号包含高次谐波,使得信号具有较高的带宽,这对通道调理电路的设计是一个很大的考验,如果设计不当,会限制信号数据率的扩展。对于高频脉冲信号的直流偏置也是通道调理电路的一个难点,直流偏置器所适用的频率范围、插损等指标都会对输出信号的波形造成很大的影响,本文将会对这些问题进行具体阐述。基于高速数据发生器在现代测试领域的重要性,本文主要针对高频脉冲信号调理技术展开研究,并将研究结论应用到数据发生器(Data Generator,简称DG)通道的设计当中。线性调理技术和非线性调理技术是信号调理技术的两个重要分支,本文根据两种调理技术分别进行相应的电路设计,通过对两种实验电路结果的分析确定出两种调理技术的优点和缺点,并确定出适合用于完成本项目设计要求的调理技术。本论文的主要内容包括：1、结合国内外发展现状,针对本项目的具体要求,结合高频脉冲信号的特点来分析通道调理技术的难点。2、对线性调理技术展开论述,并对相关技术进行研究。根据研究结果进行相应的电路设计,并根据实验结果对线性调理技术进行总结,分析出线性调理技术的优点和缺点以及所适用的范围。3、对非线性调理技术展开论述,并对相关技术进行研究。根据研究结果进行相应的电路设计,并对非线性调理技术进行总结,然后分析出非线性调理技术所适用的范围。最后给出线性调理技术与非线性调理技术的区别。
[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 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.
