作为Keysight的“适配器移除”技术专有权

适配器移除方法与“微波元件测量手册”第9.3.1节中公布的相同。
顺便说一句，在布莱切利公园错过了你。

  The adapter removal method is identical to that published in section 9.3.1 of the "Handbook of Microwave Component Measurements".

BTW, missed you at Bletchley Park.

干杯。
我会向那些有兴趣在家庭酿造的VNA上实施它的人指出。
> BTW，在布莱切利公园错过了你。
是的，我非常希望能够见到你 - 这是去的主要原因之一！
但是在这方面出现了一些问题。
我确实提前联系了Keysight，所以我的名字应该已经从与会者列表中删除了。
我想有很多种方法可以在VNA上开发纯S参数测量，但是你的PNA-X超出了S参数。
惭愧我买不起！
Keysight研讨会非常好 - 我似乎总是学到一些东西。
我和一些来自Virgina Diodes的人的一次对话在Keysight研讨会上特别有趣。
我记得在一个业余无线电列表上听到有人将两个X波段耿恩二极管模块的输出与魔术T相结合，并获得比两个独立功率之和更多的功率 - 即从两个耿氏二极管获得30 mW的功率
模块每个产生10 mW。
有不止一个这样的报告，尽管它似乎不太可能，但我并不完全相信它是疯了，所以我无法抗拒在Keysight研讨会上与几位Gunn二极管专家讨论这个问题。
*其中一位是苏格兰大学的学者，他在太赫兹频率上制作了耿氏二极管。
他认为这完全是垃圾。
*另一个是来自Virgina Diodes的人，他并不感到惊讶。
他基本上说通过将二极管放在Magic-T中，人们完全改变了二极管工作的腔体，因此如果它们在完全不同的腔体中以不同的模式工作，则不应该太惊讶。
希望有一些你在英国的时候见到你。

Cheers. I will point it out to someone who is interested in implementing it on a home-brew VNA.

Yes, I was rather hoping to see you too - one of the main reasons for going! But something came up at this end. I did contact Keysight in advance though, so my name should have been removed from the list of attendees. 

I guess there are are so many ways you can develop pure S-parameters measurements on a VNA, but your PNA-X's go *well* beyond S-parameters. Shame I can't afford one! 

The Keysight seminars are quite good - I always seem to learn something. One conversation I had with someone from Virgina Diodes was particularly interesting at one of the Keysight seminars. 

I recall hearing on an amateur radio list about people combining the output of two X-band Gunn diode modules with a magic-T and getting more power out than the sum of the two individual powers  - i.e. get something like 30 mW from two Gunn diode modules each producing 10 mW.  There had been more than one report of this, and as much as it seemed improbable, I was not totally convinced it was crazy, so I could not resist discussing this with a couple of Gunn diode experts at the Keysight seminar. 

* One was an academic at a Scottish university who was making Gunn diodes at THz frequencies. He dismissed it as utter rubbish. 
* The other was a guy from Virgina Diodes who was not surprised at all. He basically said that by putting the diodes in a Magic-T, one has completely changed the cavity the diodes are operating in, so one should not be too surprised if they operate in a different mode in a totally different cavity. 

Hope to see you some other time you are in the UK.
