是否有可能以编程方式获得同一扫描的频域和时域数据

你愿意分享你的MATLAB代码吗？
如果是这样，你能把它贴在帖子上吗？
我打算买一台4395A频谱/网络/阻抗分析仪。
没有TDR选项。
我还设法使用该软件以低成本获得与PNA几乎完全相同的结果（与MATAB不同，VNWA软件是免费的。许可证说它仅用于VNWA和N2PK VNA，但实际上作者没有'
反对人们将其与其他分析仪一起使用。实际上，他对它进行了修改，使我的HP 4284A LCR仪表更容易使用。该软件非常令人印象深刻。我无法将其与现代PNA进行比较，但它
它比我使用过的旧版PNA有更多的功能，还有R＆amp; S最近给我免费的Rohde＆Schwarz VGA的软件模拟器。一旦你得到padt，事实上很多时候几乎看不到默认颜色
电脑，它相当令人印象深刻.Sorrry我不知道你的问题的答案！戴夫。

  Would you be willing to share your MATLAB code? If so, could you attach it to the post. 

I've contemplated buying a 4395A spectrum/network/impedance analyser.  There's no TDR option for that. I have also managed to get virtually identical results to a PNA using the software for the low cost (<$1000) VNWA. Although the software is free,  it is not open source.  Of course MATLAB is not open source,  but there's a very good open source implementation called Octave. 

Unlike MATAB, the VNWA software is free. The license says its only to use with the VNWA and N2PK VNAs, but in practice the author doesn't object to people using it with other analysers.  In fact, he made a modification to it which enabled me more easily with my HP 4284A LCR meter.  The software is very impressive.  I can't compare it to a modern PNA, but it has a lot more functionality than the older PNA I have used, and also a software emulator of Rohde & Schwarz VBAs that R&S recently gave me free. Once you get padt the fact that the default colors are almost impossible to see on many computers,  its pretty impressive. 

Sorrry I don't know the answer to your question!

当然，你可以（基本上）同时获得两者。
您可以同时显示S21测量迹线和TD迹线。
完成全扫描后，您可以传输S21轨迹的大小（假设这是您想要的）和TD数据。
从技术上讲，您将首先传输一个数据集，然后传输另一个数据集，但无论如何数据传输时间都在1毫秒范围内;
不需要额外扫描。



     以下为原文

  Sure you can get both at (essentially) the same time.  You could have both an S21 measurement trace and a TD trace being displayed simultaneously.  Once a full sweep has completed, you can transfer the magnitude of the S21 trace (assuming that is what you want) and the TD data.  Technically, you would be transferring one data set first and then the other, but data transfer times are in the 1 millisecond range anyway; no extra sweep is needed.

如果PNA上有选项010（时域），则可以设置两条迹线，一条在频域，一条在时域（变换）。
在传输数据之前设置时域激励（开始和停止时间）。
扫描后，您可以将每个迹线传输到不进行第二次扫描。
请注意，这不是IFFT（快速傅里叶逆变换），而是通过Chirp Z变换执行的离散逆傅里叶变换，具有点间距由您设置的属性，而不是IFFT要求（通常意味着指向
时间是1 /最大频率）。
使用CZT，您可以拥有任意点间距（所有间距必须相等，但间距是任意的）。
如果将点间距设置为与IFFT要求相同，则可以获得与IFFT相同的数据。



     以下为原文

  If you have option 010 (Time Domain) on the PNA, you can setup two traces, one in frequency domain and one in time domain (transform on).  Set your time domain stimulus (start and stop times) before transferring data.  After a sweep, you can transfer each trace to without taking a second sweep.

Note that this will not be an IFFT (Inverse Fast Fourier Transform) but rather a Discrete Inverse Fourier Transform performed via a Chirp Z transform, with the property that the point spacing is set by you, not the IFFT requirements (which usually means point in time is 1/max frequency).  With CZT you can have arbitrary point spacing (all have to be equal spaced, but spacing is arbitrary).  You can get the same data as IFFT if you set the point spacing to be the same as the IFFT requirement.
