安捷伦示波器说明书解决multisim仿真速度慢multisim11.0中仿真时间步长的设定方法multisim10示波器的使用方法——同电子仿真软件MultiSIM 9中的虚拟示波器使用方法2011-06-13 22:16:43| 分类：IC -- 电子| 标签：|字号大中小订阅电子仿真软件MultiSIM 9中的虚拟示波器使用方法朱晓欣(原载《无线电》杂志07年第五期)在电子仿真软件MultiSIM 9中，除了虚拟双踪示波器和虚拟四踪示波器以外，还有两台高性能的先进示波器，它们分别是：跨国"安捷伦"公司的虚拟示波器"Agilent54622D"和美国"泰克"公司的虚拟数字存贮示波器"TektronixTDS2024"。
本刊06年第五期曾对Multisim7中的安捷伦虚拟示波器设置和显示有过简单介绍，读者可以参阅该文相关内容。
本文主要介绍安捷伦虚拟示波器的一些特殊其它功能和美国"泰克"公司的虚拟数字存贮示波器这两台高档次的示波器使用方法。
一、安捷伦虚拟示波器"Agilent54622D"的使用方法举例Agilent54622D虚拟示波器的带宽为100MHz，具有两个模拟通道和16个逻辑通道。
图一是它的放大面板图，它的各个开关、按钮及旋钮的排列和调节都和实物仪器完全一样，我们在自己的电脑里也能享受到使用高档次测量仪器的愉悦，且没有损坏仪器的担忧。
图一一、显示基本波形操作(这里以模拟通道1为例说明)首先在电子仿真软件MultiSIM 9电子平台上调出安捷伦虚拟函数信号发生器和安捷伦虚拟示波器各一台。
并按图二连好电路；双击安捷伦虚拟函数信号发生器图标"XFG1"打开电源开关，不作任何设置使用它的默认值，即：频率1kHz，幅值100mVpp的正弦波(可参阅上期介绍)。

最大显示屏
同类产品中最大的显示屏可提供最佳信号可视 性。8.5 英寸 WVGA 显示屏至少增加了超过 50% 的显示面 积，分辨率至少提升了 3.4 倍 (WVGA 800x480 与 WQVGA 480x234)。
最快更新速率
3000 X 系列采用安捷伦的 MegaZoom IV 定制 ASIC 技 术，具有高达每秒 1,000,000 个波形的更新速率。如果示 波器的波形更新非常慢，那么会令使用示波器的人感到 不便。快速波形更新速率可改善示波器显示质量，并通 过调节显示强度来显示微小的波形细节，例如噪声和抖 动。最重要的是，快速波形更新速率可提高示波器捕获 随机和偶发事件的几率。但更新速率慢的示波器难以做 到这一点。
通过添加 16 个集成的数字同步通道，您在同一台仪 器上可使用多达 20 个通道执行时间关联的触发、采集和 查看。购买 2 通道或 4 通道 DSO 后，可随时通过许可证启 用集成的 16 个数字定时通道，将 DSO 升级到 MSO。

安捷伦⽰波器使⽤⽅法Jitter Analysis Techniques Using an Agilent Infiniium OscilloscopeProduct NoteIntroductionWith higher-speed clocking and data transmission schemes in the computer and communications industries, timing margins are becoming increasingly tight.Sophisticated techniques are required to ensure that timing margins are being met and to find the source of problems if they are not.This product note discussesvarious techniques for measuring jitter and points out theiradvantages and disadvantages. It describes how to set up an Agilent Infiniium oscilloscope to make effective jitter measure-ments and the accuracy of these measurements. Some of themeasurement techniques are only available on Agilent 54845A/B and 54846A/B oscilloscopes with version A.04.00 or later software.These measurement techniques are indicated as such in the text.Jitter FundamentalsJitter is defined as the deviation of a transition from its ideal time.Jitter can be measured relative to an ideal time or to another transition. Several factors can affect jitter. Since jitter sources are independent of each other,a system will rarely encounter a worst-case jitter scenario. Only when each independent jitter source is at its worst and is aligned with the other sources will this occur. As a result, jitter is statistical in nature. Predicting the worst-case jitter in a system can take time.Jitter can be broken down into two categories:Random jitter is uncorrelated jitter caused by thermal or other physical, randomprocesses. The shape of the jitter distribution is Gaussian.For example, a well-behaved phase lock loop (PLL) wanders randomly around its nominal clock frequency.?Deterministic or systematic jitter can be caused by inter-symbol interference,crosstalk, sub-harmonicdistortion and other spurious events such as power-supply switching. It is important to understand the nature of the jitter to help diagnose its cause and, if possible, correct it. Deterministic jitter is more easily reduced or eliminated once the source has been identified.Jitter Measurement TechniquesThis product note will discuss four methods that can be used to characterize jitter in a system:Infinite persistenceHistogramsMeasurement statisticsMeasurement functionsInfinite PersistenceAgilent’s Infiniium oscilloscopes present several different views of jitter. One way to measure jitter is to trigger on one waveform edge and look at another edge while infinite persistence is turned on. To use this technique, set up the scope to trigger on a rising or falling edge and set the horizontal scale to examine the next rising or falling edge. In the Display dialog box, set persistence to infinite.This technique measurespeak-to-peak jitter and does not provide information about jitter distribution. Infinite persistence is easy to set up and will acquire data quickly, giving you the best chance to see worst-case jitter. However, since the tails of the jitter distribution theoretically go on forever, it will take a long time to measure the worst-case, peak-to-peak jitter.It is important to understandtheerror sources of this measurement. This technique is subject to oscilloscope trigger jitter–the largest contributor to timingerror in an oscilloscope. Trigger jitter results from the failure to place the waveform correctly relative to when a trigger event occurs. Since the infinite persistence technique overlaps multiple waveform acquisitions onto the scope display, and each acquisition is subject to trigger jitter, the accuracy of this technique can be limited. If your jitter margins are being met using this technique, then more advanced measurement techniques are not necessary. This product note will discuss Infiniium’s timebase and trigger specifications in detail in alater section.HistogramsThis technique not only shows worst-case jitter, but also gives a perspective on jitter distribution. Histograms do not acquire infor-mation as quickly as infinite persistence since each acquisition must be counted in the histogram measurement.To set up a histogram, trigger on an edge and set the horizontalscale and position so that you canview the next rising or fallingedge. In the Histogram dialog box,turn on a horizontal histogramand set both Y window markersto the same voltage. For example,if a clock threshold is at 800 mV,set both Y markers to this voltage.Set the X markers to the left andright of the edge (figure 1). Figure 1. Histogram of edge showing bi-modal distribution23It is often possible to determine if the jitter is random or deter-ministic by the shape of the histogram. Random jitter will have a Gaussian distribution.Infiniium displays the percentage of points within mean +/- 1, 2,and 3 standard deviations to help in determining how Gaussian the distribution is. For a Gaussian distribution these values should be 68%, 95%, and 99.7%, respec-tively. Non-Gaussian distributions usually indicate that the jitter has deterministic components.This technique has the same limitation on accuracy as the infinite persistence technique.Multiple acquisitions contribute to the histogram and they all contain the oscilloscope trigger jitter mentioned above. Measurement StatisticsThe next method involvescomputing statistics on waveform measurement results. For example,the scope can measure the period of a waveform on successive acquisitions. Simply drag the period measurement icon to the waveform that is to be measured.The statistics will indicate the mean, standard deviation, and min and max of the period measurements. You can let the scope run for a while to determine the amount of clock jitter present. This measurement is not subject to trigger jitter because it is a delta-time or relative measure-ment. Even if the waveform is not placed correctly relative to the trigger, the edges are measuredaccurately relative to each other.Figure 2. Setting up a jitter measurementThis measurement is subject to the timebase stability of the instrument, which is typically very good. This is a valid measurement technique but is slow to gather statistical information. Since the scope acquires a waveform, makes a measurement, and then acquires a waveform at a later time, most clock periods are not measured.With this technique, it is impossible to see how the period jitter varies over short periods of time. For example, if you have spread-spectrum clocking, this measurement will lump the slowest and fastest periods together.The Agilent 54845A/B and54846A/B Infiniium oscilloscopes can compute statistics on every instance of a measurement in asingle acquisition. To enable this capability, select the Jitter tab,then check “Measure all edges” in the Measurement Definitions dia-log box (figure 2).For example, instead of only measuring the first period on every acquisition or trigger event,every period can be measured and statistics gathered. This greatly increases the speed at which statistics are gathered and reduces the overall time to make jitter measurements. Statistics are accumulated across allmeasurements in the acquisition and across acquisitions.Pressing “Clear Display” will reset the measurement statistics.This feature is useful if you are probing the clock at different locations and want to reset the measurements.It is important to set up the scope correctly to make effective jitter measurements. Set the vertical scale of the channel being measured to offer the largest waveform that will fit on screen vertically. This will make the most effective use of the scope’s A/D converter.The scope should be set toreal-time acquisition mode inthe Acquisition dialog box. Since equivalent-time sampling can combine samples from different acquisitions, the scope’s trigger jitter would adversely affect jitter measurements. The averaging function should be turned off since, again, this combines multiple acquisition data.You may want to set the scopeto its maximum memory depth. This will make the scope less responsive to operate, but the scope can make many measure-ments on a single acquisition. Since jitter measurements are statistical, many measurements are desirable. Taking many acquisitions of small records will give a more random selection but will take longer than fewer large acquisitions. Having extremely deep memory is not necessary to getting good jitter measurements. Normally, measurements aremade at 10%, 50%, and 90% of thewaveform amplitude. This isconvenient for quickly makingmeasurements; however, whenmaking measurements acrossacquisitions and combiningtheir statistics this is not thebest solution.In the Measurement Definitiondialog box, Thresholds tab, themeasurement thresholds shouldbe set to absolute voltages. Forexample, if you are makingcycle-cycle jitter or periodmeasurements, set the middlevoltage threshold to your clockthreshold. Set the upper andlower voltage thresholds toroughly +/- 10% of the signalamplitude in voltage. This willestablish a band around thethreshold that the edge must gothrough to be measured and willeliminate false edge detection.In addition to the period jitter measurement, the cycle-cycle jitter measurement uses the same technique. The cycle-cycle jitter measurement, available on Agilent 54845A/B and 54846A/B oscilloscopes, is the differenceof two consecutive period measurements.Pi – P(i-1), 2 ≤i ≤nWhereP is a period measurement and n is the number of periods inthe waveform.Cycle-cycle jitter is a measure of the short-term stability of a clock. It may be acceptable for the clock frequency to change slowly over time but not vary from cycle to cycle. For this measurement, every period in the acquisition is measured regardless of how the “Measure all edges” selection is set. In this case, the statistics represent all of the cycle-cycle jitter measurements in one acquisition, or all acquisitionsif the scope is running.If absolute clock stability is required, then a period measurement should be made. If your system can track with small changes in the clock frequency, then cycle-cycle jitter should be measured.Again, if your timing marginsare being met with thistechnique, more advancedtechniques are not necessary. Itis only fairly recently that tightertiming margins have causedengineers to need other jittermeasurement techniques.45Measurement FunctionAgilent 54845A/B and 54846A/B Infiniium oscilloscopes can plot measurement results correlated to the signal being measured. For example, if every period is meas-ured, as in the case above, the measurement function will plot period measurement results on the vertical axis, time-correlated to the waveform that the period measurement is measuring (figure 3).In this example, the secondperiod is slightly longer than the first. The third period is shorter than the second. Also notice that the lengths of the measurement function lines correspond to the period and their placement corresponds to channel 1 because we are measuring period on channel 1.Using this technique, the shape of the jitter is apparent. For example, with spread-spectrum clocking you can see the modulation frequency as the period gets progressively slower and faster. This allows you to see sinusoidal shapes or other patterns in the measurement function plot (figure 4). It is also possible to correlate poor jitter results with the source waveform that caused them. This can aid not only in your design but can also ensure that the scope is measuring appropriate voltage levels when gatheringjitter statistics.Figure 3. Measurement function on a few cyclesFigure 4. Measurement function on many cyclesTo turn on the measurement function, first turn on the desired measurement to track. Measurements that can be tracked with the measurement function are rise time, fall time, period, frequency, cycle-cycle jitter, + width, - width and duty cycle. The measurement function is enabled in the Waveform Math dialog box (figure 5). Select a function that is a different color than the channel you are measuring to make it easier to see. Set the function operator to “measurement.” Select the measurement you wish to track and turn on the measurement function. The math function now plots the measurement results on the vertical axis, time-correlated to the channel being measured. Only one measurement function can be enabled at a time; however, the function can beset to track any of the currently active measurements listed above.Set up the acquisition by selectingthe maximum memory depth inthe Acquisition dialog box. Turnoff averaging and Sin(X)/Xinterpolation in the Acquisitiondialog box. Set the sample rateso that you are getting at leastseveral sample points on theedges that you are measuring.Measurements are made on thedata that is windowed by thescreen. To see something slowerthat may be coupling into yourclock, for example, you will needto compress the channel data onthe screen.Now that the memory depth andsample rate are fixed, you canadjust the horizontal scale sothat all of the acquired data ison screen. In order to make fulluse of the A/D converter andseparate the waveforms on thedisplay, you may want to split thegrid into two parts. If you havea very dense waveform that isbeing measured, it will be nearlyimpossible to see the measurementfunction on top of it. Turn on thesplit grid in the Display dialog box. Figure 5. Setting up a measurement function6Sources of Measurement ErrorIn this section we will examine some of the principal sources of jitter measurement error. For best accuracy, the scope should be making measurements at the same temperature as when the scope was last calibrated. If the temperature has varied by more than 5 degrees, the softwareself-calibration should be performed again. The Calibration dialog box shows the change from the calibration temperature. Trigger JitterThe most common source of error across multiple acquisitions is trigger jitter. This is the error associated with placing the first point and all subsequent points of the waveform relative towhen the trigger occurs.For Infiniium models 54830B, 54831B, and 54832B, trigger jitter is 8 ps RMS. For the 54845A/B and 54846A/B, trigger jitter is8ps RMS. Figure 6 shows a 54845B measuring its trigger jitter using its own aux out signal. If the jitter is Gaussian, youcan convert RMS jitter topeak-to-peak jitter by multiplyingthe RMS jitter by 6. Trigger jitteris only relevant if you aremeasuring absolute times asopposed to relative times. Forexample, the histogram techniquedescribed above has this errorsource, but a period measurementdoes not since it is a delta-time orrelative measurement.Figure 6. Histogram of trigger jitterThis source of error can also bepresent in period measurementsif the scope is in equivalent time.In equivalent time, the scope maycombine data points from multipleacquisitions. The scope alsocombines points from multipleacquisitions in real-time averagingmode. If it is possible, jittermeasurements should be maderelative to other edges inreal-time, non-averaged mode.78Sources of Measurement Error (continued)Timebase StabilityInfiniium uses a highly stable crystal oscillator as a source for the sample clock. Errors resulting from instability of the timebase are the least significant. Timebase stability is not a specified quantity but is typically 5 ps RMS for the 54845 and 54846. For the 54830,54831, and 54832, it is typically 2ps RMS. These measurements were made at the sametemperature as the calibration.Vertical NoiseErrors in the vertical portion of the signal path including the A/D converter and preamplifier also contribute to the scope’s jitter.Any misplacement of thewaveform vertically will translate through the slew rate of the signal into time error (figure 7). If the slew rate of the signal atthe point of measurement issteep, then the vertical error will translate into a small time jitter.If the slew rate is slow, however,this can be the most significantsource of error.Figure 7. How vertical errors contribute to time errorsAliasing and InterpolationFrom the previous section, it is clear that the signal should have a high slew rate to alleviate vertical errors. However, this can lead to signal aliasing. If the signal is not sampled sufficiently, significant time errors will be present up to the sample interval. When the scope makes measurements, it interpolates the samples above and below the measurement threshold to get the time of the level crossing. If the interpolation filter is enabled, up to 16interpolated points may be placed between two adjacent acquisition samples. Beyond this, linearinterpolation is used to determine the threshold crossing times.However, samples will only be added if the record length is less than 16K samples.A Case StudyTo illustrate how to use the jitter analysis capability of an Agilent Infiniium oscilloscope, let’s examine a typical problem. You suspect that your power supply or another slower speed clock is coupling into the main clock on the board that you are designing. In order to understand how to eliminate the problem, you would like to know the frequency and wave shape of the signal that is coupling into your clock. Traditionally, you would use an FFT magnitude spectrum and look at the side bands from the fundamental. For example, in figure 8 we have acquired a long record of a number of clock pulses and computed the FFT magnitude with a waveform math function. After we zoom in on the fundamental frequency of the clock, you can see side bands.If we take the difference in frequency from the fundamental to the nearest side band, we can determine the frequency of the coupling signal. In this example, it is measured at 198 kHz. We can also notice the odd harmonics and guess that the coupling signal would not be a sine wave. The resolution of the FFT will not give us a great deal of accuracy in determining the frequency, and we can not really see the shape of the coupling signal.To solve this problem using thejitter analysis capability, we needto think about the problem in adifferent way. If a slower signalwere modulating a higherfrequency signal, then we wouldexpect the period of the higherfrequency signal to get slightlylonger, then slightly shorter, etc.,according to the slower signal(figure 8). The measurementfunction method described earlierin this product note could beused to plot how the periodchanges across the waveform.To set up the scope, acquirethe channel data with a longacquisition record in real-timeacquisition mode. Put all of thewaveform on screen by settingthe sample rate to manual andadjusting the time per division.This will allow you to see how theperiod varies across the entireacquisition. In the MeasurementDefinitions dialog box, Jitter tab,set the control to Measure AllEdges (figure 2). Now, turn ona period measurement. In theMath dialog box, turn on theMeasurement function and setto the period measurement. Figure 8. FFT of clock910A Case Study (continued)You can now see how the period measurement varies across the signal (figure 9). Adjust the time per division until you can see several periods of the slower speed signal in the measurement function. To measure the frequency, use the markers or simply drag the frequencymeasurement to the measurement function. Using this technique, we measure 197 kHz and we can see that the signal is a square wave.This confirms that another signal on the board is coupling into the clock. Armed with this knowledge,we are better equipped to find a solution.SummaryThis product note presents several methods for measuring jitter with Agilent’s Infiniium oscilloscopes.

什么是波形波形捕获率 ?
当示波器采集、处理数据并在屏幕上绘制数据图形时，不可避免存在 "死区时间"，也就 是示波器完全遗漏信号的时间。总之，波形更新率越快，死区时间越短。死区时间越 短，示波器越有可能捕获到异常和偶发的事件。因此，选择具有极快波形更新率的示波 器至关重要。图 7 和 8 展示了示波器在两种波形捕获率下的区别。

Pt = 100 x (1-[1-RW](U x t) )
式中 Pt = 在 "t" 秒内捕获异常事件的几率 t = 观察时间 U = 示波器的测量波形波形捕获率 R = 异常事件发生率 W = 显示采集窗口 = 时基设置 x 10
因此，选择一款拥有最快速且毫不妥协的波形捕获率的示波器是很有必要的，它可为 您提供充足的时间来提高找到信号异常的概率。除了测量波形捕获率外，表 1 还显示了 示波器查在 5 秒钟的采集过程中，看到毛刺信号的概率为每秒钟 5 次。使用 3000T X 系 列，您可以最大限度地提高查看偶发毛刺信号的几率。但在使用其他同类产品时，如 果您同时使用任何其他的功能特性，比如说测量、搜索或数字通道，示波器的波形捕 获率就会变得相当缓慢。您唯一的应对方法就是延长示波器的运行时间。举个例子， 假如您正在使用数字通道，您就必须要使示波器运行超过 8,000 倍的时间长度，才能接 近 3000T X 系列波形捕获率下的概率。两款示波器发现毛刺信号所花费的的时间竟达到 了 12 小时比 5 秒钟的巨大差距!
但类似的技术指标并不意味着相同的性能。
许多厂商所宣传的波形捕获率技术指标仅在特定模式下可以实现，或是需要关闭任何其 他的功能特性。表 1 显示了 3000T X 系列的波形捕获率与同类产品的比较。
虽然所有示波器的波形捕获率在某种程度上都会受到时基设置的影响，但重要的是，波 形捕获率能在您使用任何的示波器功能时保持不变。
