亲爱的先生：我是VNA平衡测量的新手。过去，安捷伦过去常常分发大量免费软件，以便向客户介绍最新的行业发展。关于平衡S参数测量，有人可以告诉我是否有任何免费软件可以帮助用户更好地理解平衡的VNA测量。在过去，安捷伦过去常常分发包含问题的应用笔记，提供数字输入和解决方案的问题，任何人都可以向我指出详细的应用说明，以帮助我更好地理解平衡的VNA测量。虽然首选软件，但也欢迎提供应用说明。感谢您过去的反馈。 以上来自于谷歌翻译 以下为原文Dear Sir: I am new to VNA balanced measurements. In the past, Agilent used to distribute a lot of free software to educate their customers with regard to the latest industry developments. With regard to balanced S parameter measurements, can someone please tell me if there is any free software that will help the user understand balanced VNA measurements better. In the past, Agilent used to distribute application notes that contained worked out problems, problems that offered numerical inputs and solutions, can anyone point me to a detailed application note to help me understand balanced VNA measurements better. Although software is preferred, an application note will also be welcome. Thank you for your past feedback.

在典型使用过程中，我应采取哪些措施来保护HP8753网络分析仪免受ESD（静电消除）的损坏？我应该戴上防静电腕带吗？我一直在使用HP8753一段时间没有遵循任何过程来保护设备免受ESD。我使用的唯一端口是前面的两个主要APC-7连接器，我还没有遇到任何问题。尽管到目前为止这项工作仍然顺利，但我想确保了解行业中通常遵循的ESD实践。任何输入将非常感激。感谢编辑：theham1于2014年4月14日下午3:31 以上来自于谷歌翻译 以下为原文What measures should I take to protect my HP8753 network analyzer from damage due to ESD (electrostatic dischard) during typical use? Should I ground myself with an ESD wrist strap? I've been using an HP8753 for a while now without following any sort of process to protect the device against ESD. The only ports I ever use are the two main APC-7 connectors on the front, and I haven't yet had any problems. Even though this has worked fine so far I want to be sure I understand what ESD practices are typically followed in the industry. Any input would be much appreciated.

大家问候！在我的工作场所，我们正在探索为VDI实验室提供一些GPU支持。正如我的同事和我开始研究K1和K1之间的差异。 K2（网格1.0 ??）和特斯拉（GRID 2.0）存在一些实质性差异。所以你现在用GRID 2.0告诉我，我必须购买硬件（Tesla M60.M6）和使用GPU的软件许可？如果这个假设是正确的，那么由于许可成本，GRID 2.0的总体拥有成本将增加30％。当我们比较K1＆amp; K2，我们不必担心许可模式，但是当涉及到GRID 2.0时，我们必须以并发使用模式和年度支持许可我们的用户？他们可以为教育机构提供折扣吗？当我们添加数字时，对于具有NVIDIA许可模式的VDI中的任何GPU都没有意义。我误会了什么吗？以上来自于谷歌翻译以下为原文Greetings everyone!At my workplace, we are exploring offering our VDI labs some GPU support.As my co-worker and I start looking over the differences between the K1 & K2 (Grid 1.0??) and Tesla (GRID 2.0), there are some substantial differences.So you are telling me now with GRID 2.0, I have to purchase the hardware (Tesla M60. M6) and the software licensing to use GPU ?If that assumption is correct, the TCO for the GRID 2.0 is 30% more all because of the licensing costs.When we both compared the K1 & K2, we didn't have to worry about licensing model but when it comes to the GRID 2.0, we have to license our users on a concurrent usage model and yearly support ? is their a discount available for educational institutions ?When we add the numbers up, it doesn't make sense for any GPU in a VDI with the licensing model NVIDIA has in place.Am I misunderstanding something ?

我有ACY8C2494芯片（QFN68）。我知道我可以用MixPrim1设备连接到我的PC上编程它，但是我如何将MICROPRO1与CYY8C2494接口呢？是否有适配器可用，如果有的话，我在哪里可以找到它们？ 以上来自于百度翻译 以下为原文I have a CY8C24994 chip (QFN68). I understand that I can program it using a MiniProg1 device connected to my PC. But how do I interface the CY8C24994 with the MiniProg1? Are there adaptors available and if yes, where can I find them?

我有E8362B与080,081,083,014，UNL，H11等也是83631B信号发生器。我没有任何参考调音台或金色。 1.使用这些硬件我可以对混音器进行什么类型的测试？ 2.我只想测量调音台的转换损耗（仅限幅度），请告诉我还需要什么？ 3.我在校准菜单A.06.0＃4中找不到SMC / VMC校准。当我启用频率偏移时，我发现了锁相丢失错误。 5.PNA接受83631B它作为GPIB 19的信号发生器，但有些错误。我可以将它用作混音器测试的外部信号发生器吗？ 6.如果PNA不接受这个，有没有办法使用PNA内的VBA脚本命令来控制它，并开发自定义测试。任何详细的应用程序链接。笔记或教程将受到极大关注。 Zubair Rafiq 以上来自于谷歌翻译 以下为原文I have E8362B with 080,081,083,014,UNL,H11 etc. also83631B Signal generator. I don’t have any reference mixer or golden.1.With these hardware what type test to a mixer I can perform? 2.I want just measure Conversion loss(magnitude only) of a mixer,kindly tell me what else is required? 3.I could not found SMC/VMC calibration in Calibration menu A.06.0#4.When I enable Frequency Offset I found Phase Lock Lost error. 5.PNA accepts 83631B it as a signal generator at GPIB 19 but some error. Can I use this as an external signal generator for mixer testing? 6.If PNA does not accept this, is there any way to control this using VBA scripts commands inside PNA and develop customize test.any link to detailed app. note or tutorial will be greatly appriciated.

你好， 背景：我们在固件中使用SPC56EL70及其Flash驱动程序。 问题描述：在使用Flash驱动程序的Erase API时，我们已经擦除了闪存的影子存储区。 在擦除该区域之后，当MCU被给予硬复位（通过电源开/关循环）时，观察到它不可用。 调试器未连接到MCU，我们无法下载新的固件。 问题严重性：影子存储器擦除已在我们所有5个MCU板上执行，因此所有5个板已经不存在。 我们需要紧急的帮助和支持，将董事会恢复到工作状态。请提供指导，帮助我们克服这个问题。 非常感谢提前。以上来自于谷歌翻译以下为原文 Hello, Background: We are using the SPC56EL70 and it's Flash driver in our Firmware. Problem description: While using the Erase API of the Flash driver we have erased the shadow memory area of the Flash memory. After having erased this area, when the MCU was given a hard reset (by a Power ON/OFF cycle), it is observed to be unusable. The debugger does not connect to the MCU, and we are unable to download new Firmware. Problem severity: The shadow memory erase has been executed on all 5 of our MCU boards, as a result of which all 5 boards have become defunct. We need urgent help and support to restore the boards to a working state. Kindly provide guidance to help us overcome this problem. Thanks a lot in advance.

如果这是一个愚蠢的问题，我很抱歉，但我不知道这是为了什么。它似乎适用于一般桌面使用，以及Creative Cloud等图形程序和类似的应用程序。但我觉得它真的很贵，而且一家公司也可以提供高功率的笔记本电脑。不要误解我的意思，这很酷，效果很好，我只是不知道它的用途。一个人公司或家庭使用是否有意义？谢谢你的时间！以上来自于谷歌翻译以下为原文I'm sorry if this is a stupid question, but I just don't know who this is for. It seems like it's for general desktop use, and graphic programs like Creative Cloud and applications like that. But I feel like it would be really expensive, and a company might as well give out high powered laptops instead. Don't get me wrong, this is cool and it works great, I just don't get what it's for. Would it make sense for one man companies or home use?Thanks for your time!

你好，我有一个HP8711A SN 3212A00581与Boot A02.00和固件A.01.52日期1992年11月3日该单元有1.5MB DRAM和选项1E1我在磁盘上有两个版本的固件A.02.10和A.03.52我会想知道我是否能够将固件更新到2.10或3.52而不用我的单元。还有办法在尝试升级之前备份仪器中的当前固件吗？我知道我必须预先备份校准常数。此外，我想在某些时候更新单元到8712A的功能，如果可能的话。这真的是火腿小屋的一个很好的补充。我注意到该装置有28F010用于启动，混合使用28F010和28F010。还有没有人有这些分析仪的“A”版本的原理图的CLIP？谢谢你，73，Sam W3OHM 以上来自于谷歌翻译 以下为原文Hello, I have a HP8711A SN 3212A00581 with Boot A02.00 and Firmware A.01.52 Dated Nov 3, 1992 The unit has 1.5MB DRAM and Option 1E1 I have on disk two versions of the firmware A.02.10 and A.03.52 I would like to know if I will be able to update the firmware to 2.10 or the 3.52 without bricking my unit. Also is there a way to back up the current firmware in the instrument before attempting an upgrade? I know that I have to make a backup of the calibration constants beforehand. Also I would like at some point to update the unit to the functionality of the 8712A if that is possible. That would really be a nice addition to the ham shack. I noted that the unit has 28F010 for boot and a mix of 28F010 and 28F010 parts. Also does anyone have a CLIP of the schematics for the "A" version of these analyzers? Thank you and 73, Sam W3OHM
