如何利用HP 8720B从S参数获得复磁导率和介电常数

问答对人有帮助，内容完整，我也想知道答案 0 问候。我正在尝试使用旧的HP 8720A VNA测量1-20 GHz范围内样品的复杂渗透率和介电常数。我希望找到的是用于将S参数转换为磁导率和介电常数的软件。我本来打算用简单的Nicolson-Ross-Weir方法进行编码，但我刚刚得知PI驱动这个项目，我可以预期样品组可能有也可能没有导电性，可能是否有磁性，可能或者不是有损的，可能有也可能没有固定的样本量。通过NIST技术说明1536等文献，我很快就被这种病态受限的样本集的建模可能性所震撼。当购买8720A时，购买了这样的软件，但媒体早已不复存在。对商业和优选免费软件/共享软件的任何建议？ -Syms 以上来自于谷歌翻译以下为原文 Greetings. I am trying to measure the complex permeability and permittivity of samples in the 1-20 GHz range using an old HP 8720A VNA. What I'm hoping to find is software for converting the S-parameters to permeability and permittivity. I had intended on just coding a simple Nicolson-Ross-Weir method, but I've just been informed by the PI driving this project that I can expect sample set that may or may not be conductive, may or not be magnetic, and may or not be lossy, and may or may not have a fixed sample size. Going through the literature such as NIST technical note 1536, I am quickly overwhelmed by the modelling possibilities for such an ill constrained sample set. When the 8720A was purchased, such software was purchased but the media is long gone. Any suggestions for commercial and preferably freeware/shareware software? -Syms 0

答案对人有帮助，有参考价值 0 我们生产的产品（并且已经存在多年）确实可以用于各种材料测量。它被称为材料测量软件！链接在这里：http：//cp.literature.agilent.com/litweb/pdf/5988-9472EN.pdf; 我刚检查过，支持矩阵不包括8720B。您可以联系Agiletn呼叫中心，看看是否有任何未列出的8720B支持。编辑：Dr_joel于2012年7月11日下午10:25 以上来自于谷歌翻译以下为原文 We produce a product (and have for many years) that does exactly this for a wide variety of materials measurements. It is called the Material Measurements Software! Link's here: http://cp.literature.agilent.com/litweb/pdf/5988-9472EN.pdf; I just checked and the support matrix doesn't include 8720B. You might contact Agiletn call center to see if there is any non-listed support for 8720B. Edited by: Dr_joel on Jul 11, 2012 10:25 PM

答案对人有帮助，有参考价值 0 脑洞大赛9 发表于 2019-7-26 18:24 我们生产的产品（并且已经存在多年）确实可以用于各种材料测量。它被称为材料测量软件！链接在这里：http：//cp.literature.agilent.com/litweb/pdf/5988-9472EN.pdf; 嗨！我是呼叫中心的应用工程师，我支持8507x系列软件。自2001年以来，8720B分析仪已经过时，没有任何支持，因此我对85071支持8720系列分析仪的大部分知识必须从内存中调用。在85071E版本的E.04和E.05软件中有8720系列的传统支持。我不记得确切支持8720的哪个特定版本（有8720B型号，8720C，8720D，8720ES / ET是最后一个版本）。您+可能+能够获得该软件的“Legacy”E.05版本，以便通过GPIB与8720B进行通信，因为872x系列通信驱动程序已经保留。但是，没有保证功能，我们将无法在呼叫中心支持此设置。我无法验证它是否可行，因为我不再有8720B坐在我身后的联络中心进行测试。您可以从以下网站下载该软件：8507x系列：软件下载页面。该软件附带免费 2周试用许可证。购买之前试一试！在页面的右侧，靠近底部，您将看到一个标题为“Legacy Analyzers”的框，您可以在此下载85071E软件的旧版本（修订版85071E.05.01.21）。值得注意的是，该软件的旧版本（修订版85071E.05.01.21）将不会更新。试用85071E的旧版本，使用GPIB与8720B进行通信，看看它是否适合你。编辑：MarkH于2012年8月8日下午5:50 以上来自于谷歌翻译以下为原文 Hi! I am an application engineer at the call center and I support the 8507x family of software. The 8720B analyzer has been obsolete with no support since 2001, as a result much of my knowledge of the 85071 support the 8720 series of analyzers has to be recalled from memory. There was legacy support for the 8720 family in the 85071E version E.04 and E.05 software. I do not remember exactly which specific versions of the 8720 were supported (there was an 8720B model, an 8720C, an 8720D, and the 8720ES/ET was the last version). You +might+ be able to get the "Legacy" E.05 version of the software to communicate with the 8720B over GPIB since the 872x family communication drivers were left in. However, there is no guarantee of functionality and we will be unable to support this setup at the call center. I cannot verify if it will work or not because I no longer have an 8720B sitting in behind me in the contact center to test with. You can download the software from this website: 8507x Series: Software Downloads Page. The software comes with a free 2 week trial license. Try it out before you buy! Off to the right hand side of the page, near the bottom, you will see a box titled "Legacy Analyzers", here you can download the legacy release of the 85071E software (revision 85071E.05.01.21). It is worth noting that that the legacy version of the software (revision 85071E.05.01.21) will not be updated. Try out the legacy version of the 85071E out using GPIB to communicate with the 8720B and see if it works for you. Edited by: MarkH on Aug 8, 2012 5:50 PM
