无法绘制多个S2P文件

嗨sdgrant，谢谢你的回复。
您提供的建议对于少量数据文件的一次性作业非常有用。
我可能应该解释为什么我创建了精心编制的索引。
我拥有的文件数量不小。
它超过100，我最终可能会添加更多文件。
每个s2p文件对应于特定的DUT。
就我而言，它是过滤数据。
一旦我将这些数据导入ADS，它就能让我有能力搜索特定的通带和拒绝。
我最终使用ADS中的“查找”功能来获取符合我要求的文件的索引值。
虽然我能够找到索引值，但我发现无法绘制它们。
希望这有助于澄清我的要求。
谢谢，阿斯温

  Hi sdgrant,
Thank you for the reply.
The suggestion you give would be useful for one time job for small quantity data files.
I probably should explain why I created the elaborate indexing.
The number of files I have is not small quantity. Its more than 100 and I might end up adding more files. Each s2p file corresponds to a particular DUT. In my case it is Filter data. Once I bring in this data into ADS its gives me the power to search for a particular pas***and and rejection. I end up using the "find" function in ADS to get the index values of files that meet my requirement. While I am able to find the index values, I find it not possible to plot them.
Hope this helps in clarifying my requirement.
Thanks,
Aswin

是的，了解一些背景知识肯定有帮助，而不仅仅是对基本任务的简单描述。
要在扫描中获取特定索引（文件编号）的特定结果集，可以使用跟踪表达式后面的 [N，:: ]语法。
因此，要显示来自file3.s2p和file5.s2p的第3和第5组s参数数据，请使用以下跟踪表达式dB（S（2,1）） [2，:: ] dB（S（2）
，1）） [4，:: ]数字表示文件编号索引 - 1.“查找”功能应该给出这个N值，这样就不会与文件名编号对齐。
在内部，第一个值被索引为0，因此您始终可以向扫描添加虚拟零值以对齐主文件索引号。
此语法中的第二个值“::”表示扫描中的所有频率值。



     以下为原文

  Yes, it certainly helps to know a little bit of the background and not just the simple description of the basic task.

To get to a specific set of results for a particular index (Filenumber) in the sweep you can use the [N,::] syntax following the Trace Expression. So to display for example the 3rd and 5th sets of s-parameter data from file3.s2p and file5.s2p use the following Trace Expressions

dB(S(2,1))[2,::]
dB(S(2,1))[4,::]

The number represents the Filenumber index - 1. The 'Find' function should give this N value so this will not line up with the filename number. Internally the first value is indexed as 0, so you could always add a dummy zero value to the sweep to align the main file index numbers.

The second value in this syntax, the "::", represents all frequency values in the sweep.

嗨sdgrant，谢谢你的回复。
我强调，对于dB（S（2,1））函数，第一个参数对应于“文件索引数组”，第二个参数对应于“频率”数组。
这就是我设置S参数扫描的方式。
我也明白我可以使用表达式“dB（S（2,1）[[::，]]）”来绘制所有文件，或者使用表达式dB（S（2，
1）[[0，::]]）。
我的要求是将我从“查找”功能得到的数组传递给图“dB（S（2,1））”函数，这样我就可以用图形方式查看“查找”功能的结果。
原因是我从“查找”函数得到的数组必然会根据我要求“查找”函数搜索的参数而变化。
例如，我会搜索特定的中心频率等。谢谢，Aswin



     以下为原文

  Hi sdgrant,
Thanks for the reply.
I understad that, for the dB(S(2,1)) function, the first argument corresponds to "file index array" and the second argument corresponds to the "frequency" array. That is the way I have set the S-Parameter sweep.  

I also understand that I can plot all the files by using the expression "dB(S(2,1)[[::,::]])" or plot one file at a time using the expression dB(S(2,1)[[0,::]]). 

My requirement is to pass the array I get from the "find" function to the plot "dB(S(2,1))" function, so that I can graphically see the results of the "find" function. The reason is that the array I get from the "find" function is bound to vary depending on the parameter I ask the "find" function to search. For instance, I would be searching for a particular center frequency etc.

Thanks,
Aswin

+ *订阅* +我也对此可能的解决方案感兴趣。
欧洲支持放弃了我非常相似的主题（通过从find函数获得的索引重新排列数据数组）。

I'm also interested in a possible solution for this. European support gave up on my rather similar topic (re-arrange data array by indices obtained from find function).

嗨aehoward，我确实探索了你建议的例子。
我面临的基本问题不是将一组S2P文件带入ADS。
问题在于显示2D数组，第一个自变量采用任意值。
在给出的示例中，绘制了所有扫描数据。
我想过滤掉一些扫描数据并绘制它们。
请查看邮件1和5，以获得有关上述声明的更多说明。
谢谢，阿斯温



     以下为原文

  Hi aehoward,

I did explore the example you had suggested.
The basic problem I am facing is not in taking an set of S2P files into ADS. 

The problem is in displaying a 2D array with the first independent variable taking arbitrary values. 
In the examples given all the swept data is plotted. I would like to filter out some of the swept data and plot them.

Please review mail 1 and 5 for more clarification on the above statement.
Thanks,
Aswin

嗨霍华德，这是我尝试过的第一件事。
它不起作用。
:(随着时间的推移，我想我将不得不满足于一次显示一个数据。我打算设置一个带有标记的索引，可以移动来查看各种文件。可能我可以创建一个
自定义AEL将根据查找结果创建一个单独的数组是解决我的问题的一种方法。再次感谢.Aswin



     以下为原文

  Hi Howard,
That was the first thing I tried. It did not work. :(
With the time available in hand, I think I will have to settle for displaying one data at a time. I plan to set up an index with markers that can be moved to look at the various files.
May be I can create an custom AEL which will create a seperate array based on the find results is one way to solve my problem.
Thanks again.
Aswin

嗨Aswin，我需要为我的一个项目提供类似的功能，所以我今天编写了一个自定义表达式来完成这项工作，并且也应该满足您的需求。
附有我的代码的ael文件。
这将转到+ $ HOME / hpeesof / expressions / ael / +目录。
如果您已有该文件，请将我的代码复制到您的文件中。
新函数+ Muehlhaus_extract_data +有两个参数：第一个参数是扫描数据，第二个参数是带有find函数索引的1D数组（或者在我的情况下来自sort函数）。
例如，如果您的2D扫描数据超过10个扫描值并且您调用函数Muehlhaus_extract_data（S， [0,3,5 ]），它将返回带有S参数的2D数据，用于扫描索引0和3和5
我需要1D和2D扫描的代码（扫描参数有/无频率扫描），因此代码可以处理这两种情况。
对于您的情况，如果您愿意，可以简化代码。
如果这有帮助，请告诉我！
最好的问候Volker ~~~编辑：下面的代码可能已损坏，因为论坛软件没有正确显示方括号。

  Hi Aswin,

I needed similar functionality for one of my projects, so I coded a custom expression today that does the job for me, and should also work for your needs. The ael file with my code is attached. This goes to the  +$HOME/hpeesof/expressions/ael/+  directory. If you already have that file, copy my code into your file.

The new function +Muehlhaus_extract_data+ takes two parameters: the first parameter is your swept data, and the second parameter is the 1D array with indices from the find function (or in my case from sort function). For example, if your 2D sweep data is over 10 sweep values and you call the function Muehlhaus_extract_data(S, [0,3,5]) it will return 2D-data with S-parameters for sweep index 0 and 3 and 5. 

I needed the code for both 1D and 2D sweeps (sweep over parameter with/without frequency sweep), so the code can handle both cases. For you case, you could simplify the code, if you wish.

Let me know if this helps or not!

Best regards
Volker
