您好,我的设计工程师向我询问,使用梳状滤波器发生器的SMC +相位校准的精度/不确定度水平与使用参考/校准混频器+ IF滤波器的传统VMC校准相比,因为它与群延迟和相移有关(
通过功率扫描)测量。 我们测试的频率范围是Ku波段和Ka波段下变频器。 我认为梳状滤波器发生器技术应该更准确。 那是对的吗? 是否有解决此问题的应用说明? 谢谢,rok 以上来自于谷歌翻译 以下为原文 Hello, I was asked by my design engineers what were the accuracy/uncertainty levels of the SMC+Phase calibration using a comb filter generator versus a traditional VMC calibration with reference/calibration mixer+IF filter as it pertains to group delay and phase shift(over a power sweep) measurements. The frequency ranges we test are Ku band and Ka band downconverters. I'm thinking the comb filter generator technique should be more accurate. Is that correct? Is there an application note that addresses this? Thanks, rok |

嗨Dara和Joel博士,感谢您的回复。 我会把它反馈给我的团队。 我还从Dara发布的链接下载了“不确定性计算器”。 但是,当我尝试在Excel 2010下打开excel文件时,出现“受保护的视图”错误,说明以下内容:'Office检测到此文件有问题。 编辑它可能很危险。 为了确保您的计算机安全,此文件已在受保护的视图中打开。 我只是忽略了错误,然后尝试单击“选择网络分析器”按钮。 我得到另一个错误'运行时错误'53':找不到文件:VNAUncert.DLL'。 我无法运行.MSI安装程序,因为它需要管理员权限,这是我没有的,因为我的计算机是由我公司的IT部门控制的。 可以发布丢失的dll文件,以便我可以试用excel文件吗? 谢谢,rok 以上来自于谷歌翻译 以下为原文 Hi Dara and Dr Joel, Thanks for the responses. I'll feed that back to my team. I also downloaded the 'Uncertainty Calculator' from the link Dara posted. However, when I tried to open up the excel file under Excel 2010, I get a 'Protected View' error, stating the following: 'Office has detected a problem with this file. Editing it may be dangerous. To help keep your computer safe this file has been opened in Protected View.' I just ignored the error and then tried to click the 'Select Network Analyzer' button. I get another error of 'Run-time error '53': File not found: VNAUncert.DLL'. I can't run the .MSI installer program because it requires administrative access, which I don't have, since my computer is controlled by my company's IT department. Can that missing dll file be posted so I can try out the excel file? Thanks, rok |

这里是。 但它可能需要注册(我不是让dll工作的专家),你可能需要成为管理员来做到这一点。 以上来自于谷歌翻译 以下为原文 here it is. But it might need to be registered (I'm no expert on getting dll to work) and you might need to be an admin to do that. 附件

嗨乔尔博士,谢谢你的努力。 看起来安捷伦论坛阻止您上传文件,因为它重命名了附件'block files.txt'。 我无法下载它,因为它导致无效的链接。 我只需将它安装在家用计算机上,然后将其复制到我的工作计算机上。 再次感谢,rok 以上来自于谷歌翻译 以下为原文 Hi Dr Joel, Thanks for trying. Looks like the Agilent forums is preventing you from uploading the file, since it renamed the attachment 'block files.txt'. And I can't download it since it leads to an invalid link. I'll just install it on my home computer and copy it over to my work computer later on. Thanks again, rok |
