PNA N3383A固定宏第三个端口在哪里？

如果您指的是Characterize Adapter宏（如下所示），它只支持2端口适配器。

  If you are referring to the Characterize Adapter Macro (shown below), it only supports 2-port adaptors.

不完全是。
在旧的PNA N3383A中，您可以使用宏安捷伦夹具应用程序在所有3个端口上进行阻抗转换。
它对50欧姆系统中的变压器测量非常有用。
问题是，当最后一个固件（我想回到2007年）出来时，第三个端口阻抗转换被禁用。
为什么？！。
您展示的应用程序是针对最新固件之一...仅支持2端口支持，并且可能无法在旧PNA上加载，或者在我向CPU和内存添加一些涡轮增压器之前在列表中加载:)附加
那个老宏的屏幕截图。
是否有适用于固件4.87的旧PNA的宏版本？
顺便说一句，看起来那个旧的宏是用Python编写的!!! ...并且从2001 WOW看到了一些关于文件的日期。

  Not exactly.
In old PNA N3383A you could do impedance conversion on all 3 port using macro Agilent Fixturing Application. It was very useful for transformer measurement in 50 ohms system. The problem is that when the last firmware  (I think back in 2007) come out the 3rd port impedance conversion was disable. Why?!.   
The App that you showing is for one of the latest firmware ... beside only 2 port support, and that probably can't be load on that old PNA, or at list before I add some turbocharger to CPU and memory:)
Attaching the screen shoot of that old macro.

Was there any macro version for that old PNA that work with firmware 4.87?

by the way, it look like that old macro was written in Python!!!...and see some date on the files from 2001 WOW.

好的 - 所以你在谈论实际的Fixturing。
它已经这么久了，我完全忘记了曾经一度固定的宏观。
它早已集成在固件中，集成版本没有任何端口数限制。
根据PNA帮助存档中的信息，版本4.87仍然使用宏进行固定，它显示有3个端口，但在帮助示例中禁用了端口3，但我假设如果宏已启用端口3
检测到它在3端口盒上运行。
不幸的是，我无法访问任何旧的PNA，因此我无法提供太多帮助，但我会将这篇文章提请我们的一位支持工程师注意。
但是，您需要记住，N3383A和4.87版本的固件都已停产，并且很长时间没有使用寿命。



     以下为原文

  Ok - so you are talking about actual Fixturing.  It has been so long, I completely forgot that at one point, fixturing used to be a macro.  it has long been integrated in the firmware and the integrated version doesn't have any port count limitations.  

Based on the information in the PNA help archive, version 4.87 was still using the macro for fixturing and it shows that there are 3 ports, but port 3 is disabled in the help examples, but I assume that port 3 would be enabled if the macro detected that it was running on a 3 port box.  Unfortunately, I don't have access to any of those older PNAs and therefore I can't really be of much help, but I will bring this post to the attention of one of our support engineers.  However, you need to keep in mind that both the N3383A and the 4.87 version of firmware are discontinued and long out of support life.

感谢Daras的回复。
它可能是特定版本的宏（2.52）中的一些错误。
我拥有的第一个版本之一（1.02）识别所有3个端口，但它看起来与固件4.87不完全兼容。
如果能够在你身边的人有时间看我会欣赏的。



     以下为原文

  Thank you Daras for response.

It might be some bug in that particular version of the macro (2.52). One of the first version that I have (1.02) recognize all 3 port, but it look like it is not fully compatible with firmware 4.87. If somebody able on yours side will have time to look in that I will appreciate.

可能能够提供帮助的人本周不在办公室，但他说当他回来时他会调查。

  the person who might be able to help is out of the office this week, but he said he will look into it when he gets back.

我认为问题是新固件需要不同的架构。
在较旧的框中，我认为存在一个问题，即当切换端口开关时，其中一个端口的负载匹配会发生变化。
FW可以容纳这一点，但前提是它识别出发生了切换。
较老的fw知道这样做，新的固件没有被设计为在较旧的盒子上运行，所以它不能支持它，我想。
但是你可以编写自己的代码来提取错误术语，应用由于固定而产生的端口偏移，并将它们重新加载到calset中。
数学很容易获得（你知道在哪里......）。



     以下为原文

  I think the trouble is the new firmware expects a different architecture.  In the older box, I believe there is an issue where the load match for one of the ports changes when the port switch is switched.  The FW can accomodate this but only if it recognizes that the switch occurs.  The older fw knows to do this, the new firmware was not desisgned to run on the older boxes and so it cannot support it, I guess.

But you could just write your own code to extract the error terms, apply the port offsets due to fixtureing, and reload them into the calset.  The math is readily available (you know where..).

我没有详细关注这个帖子，现在正在使用手机，所以我不想尝试全部阅读。
但如果它有任何帮助我在这里有一个相当恶心的N3383A。
（我认为它有PSU故障，其他人认为是一个糟糕的超级电容）。
如果在开启之前插入一些叉齿，机器可以正常工作。
我不知道它有什么固件版本，但它肯定比机械师可以采用的更老。
由于它可能会退回给我购买的卖家，我无法更改固件版本。
如果它会有所帮助，有人可以告诉我到底要做什么，我可以告诉你固件版本并告诉你我是否看到两个或三个端口。
由于我最近刚拿到机器，它可能会被退回给卖家，我没有花时间去研究它，所以任何说明都必须写得很好。
我甚至没有看过手册。

  I have not been following this thread in detail and are using a mobile phone now, so I don't fancy trying to read it all. 

But if it is of any help I have a rather sick N3383A here. (I think it has a PSU fault, someone else thinks a bad supercap). The machine does work if plugged in for some tine before switching on. I don't know what firmware version it has, but it is certainly a lot older than the machinr can take. Since it might be returned to the seller I purchased it from, I can't change the firmware version. 

If it would help, and someone could tell me exactly what to do,  I could tell you the firmware version and tell you whether I see two ports or three. 

Since I only recently got the machine,  and it will probably be returned to the seller,  I have not taken any time to really investigate it, so any instructions would have to be pretty well written.  I have not even looked at the manual for it.
