示波器探头基础系列之五——示波器探头使用指南美国力科公司概述:本文旨在帮助读者对常用的示波器探头建立一个基本认识。
此外,我们通过一系列的例子说明探头的不正确使用如何影响测量的结果。
理解探测问题注意!连接示波器和待测物会给被测波形带来失真。
示波器上应该贴上上面类似的警告标签吗?或许是的。
示波器同其它测量仪器一样,受制于各种测量问题——显然,示波器和待测物的连接会影响到测量,使用者理解这样的影响是非常重要的。
随着示波器技术的发展,连接示波器和待测物的工具和技术已经变得非常成熟。
早期的示波器,测量带宽只有几百KHz数量级,常使用电缆连接电路。
现代示波器使用各种连接技术以最小化测量误差。
使用者应该熟悉示波器本身以及示波器连接电路的各种方法的特性和限制。
考虑示波器连接待测电路的方式如何影响测量,待测电路可以等效为包含内置电阻和电容的戴维宁等效电压源。
同样,示波器输入电路和连接部分可以被等效为负载电阻和旁路电容。
该模型如图1所示。
当示波器连接信号源时,示波器的负载效应会减小测量到的电压。
低频的损耗取决于电阻比率Rs和Ro。
对于高频时的损耗,Cs和Co成了主要因素。
另外一个影响是系统带宽由于示波器的容性负载而变小,这也会影响到动态时间量的测量,如脉冲上升时间Risetime。
图1 包括信号源和示波器的简单测量模型示波器的设计者需要从两个方面入手来减少负载效应的影响:a.高阻探头,利用有源和无源电路来减少负载效应,这些电路包括补偿衰减器或者低容值场效应晶体管缓冲放大器。
b.对于高频应用的直接连接,示波器的输入电路采用50ohm的内部端接。
在这些场合,示波器输入电路被设计成常数的50ohm负载阻抗。
低电容的探头被设计为50ohm端接来减少负载效应。
如何选择合适的探头通常,探头可以被分成三大类。
1、无源高阻探头;2、无源低阻探头;3、有源探头。
针对特定应用选择特定探头,这些探头的优点和缺点都需要被仔细考虑。
表1给出了三种探头以及它们适合的频响范围和输入电压。

示波器基础系列之八——关于示波器捕获信号的基本原则及基本操作步骤汪进进 美国力科公司深圳代表处很多初学示波器的工程师最关心的是“怎么让波形出来”,这时候我们一般都被教会了要用“AutoSet”键。
但如果AutoSet之后波形还是出不来,我们往往不知所措了; 或者是即使Auto Set能使波形出来,就可以往下进行测量和分析了吗? 只有很初级的工程师会用AutoSet,所以我们很低端示波器WaveJet系列设计的AutoSet反应速度全世界最快,按一下Auto Set,1秒左右就有波形出来。
但AutoSet不能保证信号被准确地高保真地捕获。
高保真地捕获信号是操作示波器的第一要著,否则再继续一些测量和分析就没有什么意义了。
为实现高保真地捕获信号,我们需要掌握设置示波器的一些基本原则。
捕获信号的基本原则是:第一,最小化量化误差; 第二,时刻警惕采样率; 第三,至少捕获感兴趣的一个周期的低频成分; 第四,在有些时候使用一些特别的获取模式或处理方法。
首先,我们要了解示波器的屏幕显示。
示波器是人机交互的工具,每一个操作会带来屏幕上显示的变化,这变化代表什么含义? 这是基础之基础呵。
如图一所示,示波器的水平轴有十大格,捕获时间=10 x [Time/Div],调节面板上的水平时基旋钮,就会相应增加或减小捕获的时间。
展开波形可以看到波形有一个个的点组成,这相邻两点之间的时间间隔就是采样周期,是采样率的倒数。
屏幕上显示的全部点的个数就表示为示波器的存储深度。
采样率x 采样时间= 存储深度。
这是示波器的第一关系式,非常重要。
如图一右下边显示的是力科示波器的一次菜单Timebase,上面显示的三个数值,右边的两个数相乘再乘以10就等于左边的数。
在调节时基的时候我们要“keep an eye on the sample rate”——时刻警惕采样率。
示波器的垂直轴有8大格,垂直范围=8 x [Volts/Div]≈ 256二进制码,对应8位的ADC。
自定义示波器系列之一自定义示波器系列之一使用指南力科示波器MATLAB使用指南——力科示波器——美国力科公司 万力劢基于X-Stream技术的力科示波器既是一个高速信号采集平台,也是一个功能强大的信号处理平台。
示波器软件本身提供了丰富的测量和运算功能,能够满足常见的信号处理应用。
此外,力科示波器还能借助MATLAB及其丰富的函数、工具箱做更复杂、更个性化的实时信号处理。
使用MATLAB实时处理力科示波器采集的数据,可以采取以下三种方式:遥控((Remote Control)方式1.遥控MATLAB在计算机上运行,通过计算机的GPIB、以太网Ethernet或者串口RS232来控制示波器、读取采集的数据,如图1:图 1 遥控方式在这种联机方式下,MATLAB对力科示波器的控制方式又可分为1)装有MATLAB的计算机作为控制器,通过SCPI程控命令(Standard Commands for Programmable Instruments,即IEEE488.2标准)来控制示波器。
这和NI公司的Labview, LabWindows/CVI程控仪器的方式是类似的。
MathWorks公司提供了MATLAB工具箱Instrument Control Toolbox,可以方便地实现SCPI方式的程控。
详情请参考该工具箱的帮助文件以及/LeCroy。
力科示波器支持的SCPI程控指令请参考LeCroy X-Stream Oscilloscopes Remote Control Manual。
2)力科示波器软件提供了基于COM(Component Object Model)技术的自动化接口(Automation interface)。
外部程序通过这种接口可以读取示波器属性、控制示波器和采集数据。
这种方式下,力科示波器作为COM Automation server, MATLAB程序作为COM Client。
这种示波器软件与MATLAB程序分别在不同平台上运行的方式,导致两者交互数据的效率受限于GPIB/ENET/RS232接口的数据吞吐率。
