我搜索过以前关于类似问题的帖子，但仍然找不到任何有帮助的东西......我有一个N5221A PNA，E-cal N4432A（用于N型）和一个来自Maury的WR-284校准套件（S7007S）
），我试图在几个4端口定向耦合器上进行测量，输入/输出端口为WR-284，耦合端口为N型。 我原本以为我可以使用耦合器作为未知的推进器，但这些耦合器的耦合因子规格是60dB，我相信未知通过的阈值是40dB ......通过Smart-Cal，我尝试使用4端口校准 我的两个工具包，以及“修改校准”选项。 在修改选项中，我选择1）两个N类型使用Ecal作为未知通过2）两个WG类型通过3）一个WG和一个N型端口到未知通过（其中另一个WG适配器） 将被用作未知的通过）我有几个问题的程序。 首先，唯一要求的WG标准是短暂的，没有任何负载。 此外，在最后，提示要求延迟和相位偏移，给定的值都没有任何意义。 PNA提供：时间延迟= -1。＃IND相位偏移= -2147483648有人可以建议校准同轴/ WG组合的理想方法吗？ 要么调整我的上述尝试，要么使用完全不同的方法（我无法找出适配器删除方法......） 以上来自于谷歌翻译 以下为原文 I've searched through previous posts about similar issues but still didn't find anything that helped... I have a N5221A PNA, E-cal N4432A (for N-type), and a WR-284 Cal Kit from Maury (S7007S), and I'm attempting to make measurements on several 4-port directional couplers with the input/output ports being WR-284 and the coupling ports being N-type. I originally thought I could use the couplers as unknown thrus, but the coupling factor spec for these couplers is 60dB and I believe the threshold for an unknown thru is 40dB... Via Smart-Cal, I attempted to do a 4 port cal using my two kits, as well as the "Modify Cal" option. In the modify option, I selected 1) the two N-types to use the Ecal as their unknown thru 2) the two WG types to flush thru 3) one WG and one N-type port to unknown thru (where the other WG adapter would be used as the unknown thru) I have several issues with the procedure. Firstly, the only WG standard asked for is the short, no loads whatsoever. Also, at the very end, the prompt asks for delay and phase offset, neither given values make a lick of sense. The PNA provided: Time delay= -1.#IND Phase offset= -2147483648 Can someone advise the ideal way to calibrate the coax/WG combination? Either tweaking my above attempt or using a whole different approach (I could not figure out adapter removal method...)

显然我的困境并不像我想象的那样微不足道，因为似乎没有人有解决我的问题的建议。
以上来自于谷歌翻译 以下为原文 Apparently my predicament isn't as trivial as I thought, as no one seems to have and suggestions on solving my issue. |

既然你提到了N型和WG型，我猜你的耦合器有两个WG端口和两个N型端口？ 在这种情况下，最好做一个4端口类型N cal。 然后将WG连接到两个端口并执行第二个2端口TRL校准。 然后使用cal-plane-manager从前4端口cal和第2端口cal计算N到波导适配器的去嵌入网络。 然后，使用相同的calplane管理器从4端口cal的两个端口中解嵌WG适配器。 至少我就是这样做的。 以上来自于谷歌翻译 以下为原文 Since you mention both type N and WG cal, I guess you coupler has two WG ports and two Type N ports? In this case it might be best to do a 4 port type N cal. Then attached the WG to the two ports and do a second, 2 port TRL cal. Then use the cal-plane-manager to compute the de-embed network for the N to wave-guide adapter from the first 4 port cal and the second 2 port cal. Then, use the same calplane manager to de-embed the WG adapters from the two ports of the 4-port cal. At least that's how I would do it. |

脑洞大赛9 发表于 2018-9-28 20:35 如果波导校准套件定义包括允许SOLT的标准，并且您将两个端口定义为N和2作为WG，您是否可以按照向导并通过使用同轴到WG适配器来做未知？ 以上来自于谷歌翻译 以下为原文 If the waveguide cal kit definitions include standards that allow for SOLT, and you define two ports as N and 2 as WG, can you just follow the wizard and do unknown through using coax-to-WG adapters? |

kdyangcheng 发表于 2018-9-28 20:48 实际上，你可以做到这一点，这就是通常所做的事情。 但是如果你要将TRL WG（最简单）和N型混合使用，我认为在N型中只做4端口cal，然后在2端口中使用TRL cal并使用cal-plane-manager可能更容易。 如果您有1端口标准（对于波导，它通常是短路，偏移短路，负载，偏移负载），那么您有比TRL更多的连接。 但是如果你有一个端口标准，你可以在WG端口之间进行QSOLT，在WG和类型N之间进行UT。如果你设置正确，你可以有端口1和2 WG，3和4类型N，设置端口1 和2到WG和通过类型定义和方法QSOLT，然后设置端口3和4的直通，并键入Ecal UT，然后从3-2和4-1（需要一个WG到同轴适配器）的一对thrus和 然后使用UT（因为1端口的cals已经确定。 以上来自于谷歌翻译 以下为原文 Indeed, you can do exactly that, and that is what is normally done. But if you are going to mix TRL WG (easiest) with type N, I think it might be easier to do just the 4 port cal in type N, and then the TRL cal in 2 port and use cal-plane-manager. If you have the 1 port standards (for waveguide it is usually short, offset short, load, offset load) then you have a lot more connections than TRL. but if you have one port standard, you can do QSOLT between the WG ports, and UT between WG and type N. If you set it up right, you can have ports 1 and 2 WG, 3 and 4 type N, Set port 1 and 2 to WG and thru type defined and method QSOLT, then set a thru for ports 3 and 4, and type Ecal UT, and then a pair of thrus from 3-2 and 4-1 (need a WG to coax adapter) and then use UT (since the 1 port cals will have been already determined. |

脑洞大赛9 发表于 2018-9-28 20:35 谢谢你的建议。 我正在尝试去嵌入/嵌入方法，因为尝试QSOLT方法会导致整个PNA应用程序关闭。 但是，因为我没有最新的固件（我在A.09.50.13上运行），所以我实际上没有Cal Plane Manager。 我还能完成去嵌入/嵌入校准方法吗？ 我有选项“2端口去嵌入”和“4端口嵌入/去嵌入”。 虽然我有点困惑，因为在线说明提到选择已经完成的校准作为S2P文件，但保存在我的CalSet中的校准不是那种格式...不知道从哪里开始。 以上来自于谷歌翻译 以下为原文 Thank for the advice. I'm attempting the de-embed/embed method, because attempting the QSOLT method causes the entire PNA application to shut down. However, because I don't have the latest firmware (I'm running on A.09.50.13), I don't actually have the Cal Plane Manager. Can I still accomplish the de-embed/embed calibration method? I do have the options "2 Port De-embedding" and "4 Port Embed/De-embed". Although I'm a bit confused, as the online instructions mention selecting the already done calibration as a S2P file, but the calibrations saved in my CalSet are not that format... Not sure where to go from here. |

asdyj 发表于 2018-9-28 21:05 在较旧的代码中，有一个名为“characterize adapter”的宏函数可以完成类似的操作。 在这种情况下，您将需要使用2端口取消插入。 但是，如果有任何方法摆动它，我建议你升级到更新的固件; 在过去的两年中，使用更好的方法在改进校准方面取得了巨大进步。 如果QSOLT导致PNA崩溃，请直接通过joel_dunsmore@keysight.com与我联系。 如果我们可以重现它，我们可以解决它。 以上来自于谷歌翻译 以下为原文 In older code there was a macro function available called "characterize adapter" that did a quite similar thing. You will want to use the 2 port depembedding for this case. But, if there is any way to swing it, I recommend you upgrade to newer firmware; in the last 2 years there has been giant strides in improving calibration using much better methods. If QSOLT is causing a PNA crash, please contact me directly at joel_dunsmore@keysight.com. If we can reproduce it we can fix it. |
