你好。我拥有一台DSO-X 2002A 2通道70MHz 2 GSa / s示波器，我正试图通过发射器/接收器P波换能器在岩石核心内的某些边界的反射上进行双向传播。问题是我只看到示波器显示屏上的脉冲。我检查了电缆是否连接在正确的端口，经过了所有可能的配置（Itried改变波的频率，幅度，增益，阻尼，高通和低通滤波器等等，它仍然没有给我一个值得分析的信号）。我的岩石核心长度为6.5厘米，p波速度略高于4000米/秒，其中第一个也是最重要的边界是在第一个1厘米之后，尽管应该给出最高阻抗的边界是边界它的核心和铝板下面（6.5厘米），我在信号中看不到。 prtscr.jpg是脉冲发生器的规格; sig_inter.png是没有核心连接到传感器的信号; dig_read_inter.png是核心连接到传感器的信号。任何人都可以帮我弄清楚为什么我无法看到边界反射的正确信号？干杯! sig_inter.png22.0 KBprtscr.jpg112.6 KB 以上来自于谷歌翻译 以下为原文Hello. I possess a DSO-X 2002A 2 channel 70MHz 2 GSa/s oscilloscope and I'm trying to two way travel time's on reflections in some boundaries within a core of rock through a transmitter/receiver P-wave transducer. The problem is that I only see the impulse on the oscilloscope's display. I've checked the cables are connected in the right port's, went through all of the configurations possible (Itried to change the wave's frequency, amplitude, gain, damping, high and low pass filters and so on and it still isn't giving me a signal worth analyzing). My core of rock has 6,5cm lenght, p-wave velocity is a tiny bit higher than 4000m/s and the first and most importante boundary within it is just after the first 1cm although the boundary that should give the highest impedance is the boundary of the core and the aluminum plate it has underneath (at 6,5cm) which I don't see either in the signal. prtscr.jpg is the specs for the pulser; sig_inter.png is the signal without the core attached to the transducer; dig_read_inter.png is the signal with the core attachedto the transducer. Can anyone help me figure out why I haven't been able to see a proper signal with the boundaries reflections? Cheers!附件sig_read_inter.png25.3 KBsig_inter.png22.0 KBprtscr.jpg112.6 KB

你好，我相信我使用的PNA-X可能有一些内部硬件问题，但我想在发送之前进行验证。我正在使用带标准接收器的PNA-X测量下变频器的噪声系数。 （没有噪音接收器选项）。以前，我能够在有问题的PNA-X上测试单位，而噪音数字没有问题。然而，最近，它在噪声系数波形中表现出尖锐的行为。 （见附件）。我将DUT移动到另一个PNA-X并且它没有尖峰问题。我还交换了有问题的PNA-X上的测试电缆并重新测量了测量，但波形中仍然出现了这些尖峰。奇怪的部分是增益波形和回波损耗波形看起来很好，根本没有尖锐的行为。我的问题是这样的。我的假设是内部硬件问题是否正确？或者在将其送回修理之前我可以尝试一些东西吗？在PNA-X内部可能发生什么导致这种行为？谢谢，rok 以上来自于谷歌翻译 以下为原文Hello, I believe the PNA-X I am using might have some internal hardware problems, but I wanted to verify here before I send it out for repair. I am measuring the noise figure of a downconverter using a PNA-X with standard receivers. (do not have the noise receiver option). Previously, I was able to test units on that PNA-X in question with no issues on the noise figure. However, recently, its been exhibiting spiky behavior in the noise figure waveform. (see attached). I moved the DUT to another PNA-X and it didn't have the spikes issue. I also swapped the test cables on the PNA-X in question and retried the measurement, but still have those spikes appearing in the waveform. The strange part is the gain waveforms and return loss waveforms look good and have no spiky behavior at all. My question is as such. Is my assumption that it is a internal hardware issue correct? Or is there something that I can try prior to sending it back for repair? And what could be happening internally inside the PNA-X to cause such behavior?

大家早，当我在Citrix和GRID的这次旅程中进入第二年时，我们在无数配置上运行了90名Autodesk员工。我不得不说这款技术仍然是丰田普锐斯对Maclaren P1的看法。我们花了大约460,000美元来实施解决方案，即使它有点工作，如果我再次选择，我会购买90个工作站，每个2200美元。本可以节省25万美元，并且工作量会更小。让我们看看为什么，我会请其他读者聆听他们的意见。 - 即使有鼠标循环和各种其他注册攻击，AutoCAD工作区也很难通过Citrix进行配置。它仍然不准确，迟滞和痛苦。 - 网格不存在Citrix支持。您必须在网上搜索各种博客，Twitter以获取更多更新，以及第三方工具来调整系统以使其可远程操作。 -NVidia网格支持 - 嗯，这是我可以从供应商和社交媒体中的一大堆营销资料中找到的 - 我们使用K2，这是我去年买的最好的。 K220不够强大，K240不会做得很好，K260是可用的，而完整的GPU是用户想要的体面绘图。所以最多我可以把8个人放在35K美元的服务器上。这是每位用户$ 8K。 - 该软件非常多。现在我们的Win10图像将使用K240启动，但如果我改为更高的任何东西 - 我会连续重启。 - 不间断的补丁，我认为我们正在使用Xen服务器的补丁17，我们刚刚为GRID卡发布了一个积分版本，上面用K260杀死了一半的员工。 （K260可以在Windows 7上运行....） - 其他3D应用程序相当不错，SpaceGass，发明者，Navisworks和Revit似乎都比AutoCAD更好用。但他们都需要2GB视频卡，这是260个配置文件。 - 管理很简单，因为您只需更新一个工作站映像，每次更新后都需要更新每台计算机上的个人虚拟磁盘 - 在完成此操作后，允许每台计算机停机半小时。 - 网络流量和带宽很奇怪。我们运行局域网设置，一些虚拟机运行速度为60Mbit，每次运行约20分钟，其他运行速度为6左右.NFI为什么。 - 当你想要它时，电源管理和让VM打开和关闭有点受欢迎，DC有电源管理 - 但它不起作用，所以你必须使用shell。 - 别让我开始使用NVEnc和各种视频模式......实际上 - 我会在那里停下来，因为我开始听起来像个老生子。从我的经验来看，我们的系统正在运行，但最终用户和IT团队都希望我们没有实现它。虽然技术似乎很好，我们都可以制作一个看起来不错的演示，但运行工作站和服务器更简单，更便宜，同时使用DFS或PeerSync在站点之间组织数据。主要的问题是，当你实现这一点时，你是独立的，Citrix支持人员不知道什么是GRID卡，而你正处于bug之后的bug之后。我们从Citrix或GRID获得的每个新更新都可以解决一个问题，但接下来的几天您将解决新问题。我有一个由5个人组成的团队都拥有Citrix Qualifications，我们只是累了，疲惫不堪，最后一个GRID驱动程序更新打破了260个配置文件迫使我写这个。我们现在太深了，无法改变它 - 所以我们将继续尝试将其变为专业功能级别，也许M60卡更好，但我想再投入5万美元的视频卡只需一年老???祝你一切顺利，感谢你们迄今为止的阅读。以上来自于谷歌翻译以下为原文Morning all,As I enter my 2nd year on this journey with Citrix and GRID, we run 90 Autodesk employees on a myriad of configurations. I have to say that this tech is still what the Toyota Prius is to a Maclaren P1.We have spent around $460,000 implementing the solution and even though it sort of works, if i had my choice again, i would have just bought 90 workstations @ $2200 each. Would have saved myself $250K and would have a smaller workload.Lets go through why and I would ask fellow readers to chirp in with their opinions. - AutoCAD workspace is very hard to configure over Citrix, even with mouse cycles and various other reg hacks. It is still inaccurate, laggy and a pain. - Citrix support is non-existent for grid. You have to trawl the web for various blogs, twitter for more updates and 3rd party tools to tune the system to make it remotely workable. - NVidia Grid Support - well, this is all i can find from the supplier ans a tonne of marketing stuff in social media - We use K2, it was the best i could buy last year. K220 is not powerful enough, K240 wont do 3D very well, K260 is usable and a full GPU is what the user wants for a decent drawing. So at best i can put 8 people on a $35K server. That is $8K per user. - The software is very buggy. Right now our Win10 image will boot with a K240, but if i change to anything higher - i get continuous reboots. - The incessant patching, i think we are on Patch 17 for Xen server and we just had a point release for the GRID cards, which as above killed half my workforce with the K260. (K260 works on Windows 7 though....) - The other 3D apps are quite good, SpaceGass, inventor, Navisworks and Revit all seem to be much better to use than AutoCAD. But they all need 2GB vid cards which is the 260 profile. - management is easy as you only have the one workstation image to update, you do need to update the personal vDisk on each machine after each update - allow half and hour of downtime for each machine whilst this is done. - Network traffic and bandwidth is just weird. We run a LAN setup and some VM run at 60Mbit for about 20 minutes at a time and others sit at around 6. NFI why. - Power management and getting VM's to switch on and off when you want them to is a bit of hit and miss, the DC have power management - but it doesn't work, so you have to use the shell. - Dont get me started on NVEnc and the various video modes...Actually - i will stop there as i am starting to sound like whingey old man. The takeaways from my experience is that, we have the system working, but both the end users and the IT team wish we hadn't implemented it. Whilst the tech seems good and we can all make a demo that looks good, it is simpler and cheaper just to run workstations and servers, whilst using DFS or PeerSync to organise the data between sites.The main problem is that you are on your own when you implement this, Citrix support has no idea what GRID cards are and you are on the bleeding edge working around bug after bug after bug. Every new update we get from Citrix or GRID may fix one issue, but the next few days you are working around new ones. I have a team of 5 guys all with Citrix Qualifications and we are just tired, worn out and the last GRID driver update that broke the 260 profile has forced me to write this.We are in too deep to change it back now - so we will continue to try and get this to a professional functional level, maybe the M60 cards are better, but do i want to throw another $50k at video cards that are only a year old ???i wish you all the very best, thanks for reading this so far.
