你好，我叫亚斯，迈克尔。在短片中，我会给你们展示一个简单的测量任务 Hi, my name is Yass, Michael. And in the short video, I will present you a typical measurement task easily accomplished
用第二代啮齿类动物拍摄并成为矢量网络分析仪。新的“道路英寸屁”设置为矢量网络分析仪， with the second generation of the rodents shot and be vector network analyzers. The new road inch fart setting be vector network analyzer,
无论你的任务是测量电缆， offer a solid r of performance for your everyday needs, whether your task is measuring cables,
过滤器，混音器，扩音器，新的烂短裤 filters, mixers, or amplifiers, the new rotten shorts and be family with its power levels up to 15 dbm
高动态范围。高端迷走神经刺激器的稳定性是正确的选择。今天， high dynamic range. And the stability of a high end vna is the right choice. Today,
我会向你们证明并希望说服你们 I will demonstrate and hopefully convince you that the rodent fought zn b
是你的选择。我会在卡通片里测量一套双层公寓。 is the choice for you. I will measure a duplex from cartoon.
埃里克森，双层公寓包括以下几条， Now, Ericsson, the duplex are covers the following bands,
1710到1785兆赫，1805到1880兆赫 1710~1785 megahertz, and 1805~to 1880 megahertz, I will calibrate the setup
z-51自动校准装置。我们将从预设值开始测量。 using the rotten spot set in, z 51 automatic calibration unit. And we will begin the measurement with a preset.
我会把测量值设定为以下。从1开始频率。 I will configure the measurement as follows. Start frequency at 1.
5千兆赫的高频 5 gigahertz Top frequency
两千兆赫。在这个点上，因为默认是s对1。我已经连接了 at two gigahertz. At this point, because the default is the s to one trace. And I have connected
双组低频和端口一，天线和端口二，高频和端口四。 the duplex low band to port one, antenna to port two, high band, port four.
我们会在屏幕上看到低音段。我们想看到两个波段。那我就简单地 We will see on the screen, the low band. We would like to see both bands. wellSo I will simply
因为我已将高频连接到端口4，我将选择S24。 add another trace to the screen as and because I have connected the high band to port four, I will select s 24.
现在，我们看到了两个波段。 Now, we see both bands.
我会把整个图表都关掉。我们在屏幕上看到了两条轨迹。然而，我们仍然能看到 I will always kill the entire diagram. And we see both traces on the screen. However, we still see
带排斥区有很多杂音。我会调整我的测量 a lot of noise in the band reject regions. I will adjust my measurement by
最大化信噪比，选择较低的带宽。 adding some power to maximize the signal to noise ratio and selecting a lower is bandwidth.
如你所见，这两个附加设置不会影响我的测量速度。如果我们想更专注于 These two additional settings, as you see, do not affect my measurement speed. If we would like to focus more
带外区域，我们需要再加两条踪迹。我将通过 on the out of band regions, we need to add two more traces. I will accomplish this task by
复制现有频道，选择频道配置，然后复制频道和图表。利用追踪配置 copying the existing channel, so select channel config, then copy, channel and diagram. And by using the trace configure
追踪经理，我会把最后一次追踪分配到一个新频道。我会选择 trace manager, i'll simply assign the last trace to a new channel. And I will select
新的图表。屏幕上显示的是。我们把轨迹移到这里。 a new diagram. Now we have the following display on the screen. Let's move this trace down here.
母猪的上半部分有两条条纹。 soWe have both bands on the in the upper area.
低音带和高音带在低音区。现在，我们加上一些标记。 andWe have the low band and the, high band in the lower area. At this point, let's add some markers.
这些标记会帮助我们进行片段扫描。分节扫描能帮我们优化测量 These markers will help us later on set up a segmented sweep. The segmented sweep will help us optimize the measurement set up
排斥带区域。soI会选择低音段，在这里加一个标记 for the band reject region. soI will select the low band and add a marker here, and I will simply drag the marker
去我想去的地方。 to where I wanted to be.
然后我在高音区加一个标记， Then I was like the high band region, and I will also add a marker here,
标记。我会把它拖到我想让它停的地方，也就是这里。 marker. And i'll add the marker to uh drag it also to where I want it to be, which is right about here.
如果你不能用手指，我就用这个地精。我们准备好进行逐段扫描了。 If you cannot do it by finger, I just use the gnome at this point. We're ready to set up the segmented sweep.
我会回到低音段， So I will go back to the low band,
扫描类型，选择定义片段。 go to sweep sweep type and select define segments.
我会在这里加一段，注意仪器是如何自动选择所需频率范围的。停止的频率。 I will add a segment here and notice how the instrument automatically selects the desired frequency range. For the stop frequency.
我会用我的记号笔来设定频率。有一个原因是 I will use my marker to set the frequency. There was one of the reasons why
我们加了标记。我会点击显示栏，再加两栏，功率和测量带宽。 we added the markers. I will click on display columns and add two more columns, power, and measurement bandwidth.
等一下，我会告诉你我为什么需要这两列。我会再加一段 In a minute, i'll tell you why I need those 2 columns. I will add another segment
选择200兆赫的停止频率。 and select the stop frequency to two gigahertz.
所以对于波段通行区， So for the band pass region,
我想看看波纹，也许我需要更多信息。我们把点数保持在201。但因为我在乐队通行证里， i would, like to look at the ripple, maybe I need a bit more Information. So we'll keep the number of points to 201. But because I'm in the band pass,
我想防止接收器受到压缩。这里，我把功率调到0 dbm，带宽保持在1千赫。 I'd like to prevent compression to my receivers. Here, I would lower the power to zero dbm and keep the bandwidth at 1 kilohertz.
对于带排斥区，我不需要那么多点。 For the band reject regions, I don't need so many points.
soI会选择101个点，同时能让我有足够的分辨率看到发生了什么。我会保证电力 soI will select 101 points, which at the same time allows me to have enough resolution to see what's happening. And I will keep the power
让我的信噪比最大化。但是，因为我想防止 at 10:00 dbm to maximize my signal to noise ratio. However, because I would like to prevent
提高我的信噪比， noise, getting into my receivers and improve my signal to noise ratio, I will decrease the bandwidth to, let's say,
100赫兹应该够了。 100 hertz should be enough.
用这个。我已经完成了这个频道。 With this. I have completed this channel.
现在我们看到， And here, now we see,
如果我们按这个图表排序，我们就有足够的信噪比，a，非常稳定的测量 if we order scale this diagram, we see we have enough signal to noise ratio, and a, very stable measurement
在带宽带，也有排斥区。 in the bandwidth band, reject region as well.
我们用高波段，同样的方法，选择，扫描，扫描类型，找到片段。我们要记住 We go to the high band, and we go to the same process, select, sweep, sweep type, find segments. Let's keep in mind that
这是高音段。被拒的乐队在左边。 this is the high band. So our band reject is on the left side.
我们再来一次， So we will again,
添加一些片段。我们在这里用记号笔，然后在这里 add some uh segments. We use the marker here, and we'll add the additional display combs
以接近功率和测量带宽。再加上第二段。 for power and measurement bandwidth close. And we add the second segment as well.
在这里，我们把它也停在两千兆赫。我们提到了排斥带在左边。这是第一个区域。 andHere, we stop it at two gigahertz as well. So we mentioned that the band reject is on the left. So this is the first region.
这里我们将把100个点减到101个点。功率不变，带宽减少到200赫兹。 Here we will decrease the hundred number of points, to a, hundred and 1. Keep the power, but we decrease the bandwidth, 200 hertz.
我们保留点和带宽，但减少功率，选择。 For the band pass, we keep the number of points and the bandwidth, but we decrease the power, select.
测量结果很稳定。 okay andWe have a very stable measurement.
把这张图也关掉。现在我们有高波段，低波段，两个波段在一起。我们准备好校准了。 Let's kill this diagram as well. And now we have the high band, the low band, both bands together. And we are ready to calibrate.
soI会断开双簧管。我来连接自动校准装置。我们有一个四孔校准装置， soI will disconnect the duplexer. I will connect the automatic calibration unit. We have a four port calibration unit,
这样就非常简单方便了。来校准三孔装置。耶赫会用转矩范围断开连接。 which makes it very easy and convenient. To calibrate a three port setup. yeahWe will use a torque range to disconnect.
缆绳总是用适当的康涅狄格州方式来避免自己转动。我们如何连接自动校准装置并不重要。 The cables always use proper Connecticut to not rotate the cable itself. It doesn't really matter how we connect the automatic calibration units.
有一个未来叫做检测端口分配。机器会自动检测波特运动鞋 There is a future called detect port assignment. The unit will automatically detect these porter sports and
继续测量。 will continue with a measurement.
苏豪，我有意将公文包，与校准单元，分析仪端口二相连。 soHere, I'm on purpose connecting portfolio to of the calibration unit, port two of the analyzer.
因为在这种情况下，用扭矩农场更方便。 Because this is more convenient, in this case, use a torque ranch.
我会把分析仪的端口四连到自动校准装置的端口二。正确地连接训练和谈话是非常重要的 I'll connect port four of the analyzer to port two of the automatic calibration unit. Proper connect the practice and talking is essential
才能达到最大精度。我们从密钥中选择cow，从cow开始。选择如下，校准激活频道。 to achieve maximum accuracy. We select cow from the hard keys, start cow with unit. And here's the option, calibrate active channel.
还有个非常方便的选择，校准所有频道。因为我们有三个频道，我会选择这个，选择。 andThere's a very convenient option, calibrate all channels. Since we have three channels, I will select this option, select.
可以 Okay
现在，仪器在警告我。校准过程中缺少接口，非常简单。 andNow, the instrument is giving me a warning. Port for is missing from the calibration, very easy, and.
4 4
选择下一个，点击，然后他们检测到错误分配。我们准备好进入下一步了。 select next and click, then they detect poor assignment. We are ready to go move to the next step.
此时，我会选择开始校准扫描。 At this point, I will select start the calibration sweep.
我们要等校准完成，这需要几分钟或几秒钟，几分钟。 andWe wait until the calibration is finished, which will take a few minutes or seconds a. Few moments.
好 啊 Ok
所以根据复杂程度 So depending on the on the complexity
校准过程可能更长或更短。在我们这里，校准完成。 of the measurement setup, the calibration can take longer or shorter. In our case, calibration is Complete.
我会点击“应用”，重新连接二轮车。 I will click on apply and will reconnect back the duplexer.
为了达到最佳效果，使用适当的连接器护理，罗丁，施瓦兹， Again, for optimum results, use proper connector care, there is, a fantastic presentation from Rodin, Schwartz,
不要转动钢缆。 and never rotate the cable itself.
连接好之后，我们的二轮车会确保，我们把正确的波段和正确的运动连接起来。 After we have properly connected, our duplexer making sure that we connect the correct band to the correct sports.
现在，低波段到端口一，天线到端口二，高波段到端口四，我们得到了测量结果。 In this case, low band to port one, antenna to port two, and high band port four, we have the measurement results.
这样就完成了测量。 This would Complete a measurement set up.
但如果我们想看呢？我们的双层支架怎么样？匹配吗？ But what if we wanted to see? How well are our duplex supports? Are matched?
我会选择第一个频道，只需在频道上加一条线，但选择不同的显示区。 In this case, I will select the first channel, simply add a trace to the channel, but select a different display area.
天线接口匹配，我会选择s到2。看起来不错。我会在同一条线路上再加一条 andFor the antenna port match, i'll select s to two. Looks great. I will add another trace to the same
显示区，选S4作为高频信号，第三条 display area, select s four four for the high band, and a third trace
低波段选择一一。测量完毕。 and select s one one for the low band. This completes our measurement.
展示了第二代车险的一些有用特征。 This concludes the short video showcasing some of the useful features of the second generation, of the road insurance that MB vector network analyzes.
我希望我能向你证明，你的测量任务有多简单多精确。感谢收看。 I hope I was able to demonstrate how easy and accurately you can accomplish your measurement tasks. Thank you for watching.
