FOM选项80用于混频器转换损耗测量

通常，您无法直接使用FOM测量混频器（可能，但难以校准和设置）。
首先，您必须在测量输入和输出信号之间改变接收器的频率。
但是，选项082将直接测量混频器的幅度响应。
PNA-L不支持083（至少我可以看到），所以你不能轻易测量带有PNA-L的混频器的相位响应。
这是PNA或PNA-X中添加的功能之一。



     以下为原文

  Generally, you can't measure a mixer directly with FOM (it is possible, but difficult to calibrate and setup).  For one thing, you must change frequencies of the receiver between measuring the input and output signals.

However, option 082 will measure you mixer directly for amplitude response.   PNA-L doesn't support 083 (at least as I can see) and so you can't easily measure the phase response of a mixer with PNA-L.  That's one of the features that is added in the PNA or PNA-X.

Dear Dr. Joel,

In my case I have PNA N5225A, with option 080 and I have been able to measure Conversion Gain with it. But I am still trying to measure the phase in order to demonstrate that phase conjugation is happening with the Mixer Under Test (MUT). I have been reading your book (Handbook of Microwave Component Measurements With Advanced VNA Techniques) in section 7.4.3.2 (Parallel Path Using a Reference Mixer) and it says that calibration needed to perform this technique (7.5.3.1 Reciprocal Calibration-Mixer Reflection Method) a filter must be added to the output of the reference mixer.

My first question is: Is this filter totally necessary? Because it is not worth it to have a different filter depending on the output frequency of your MUT.

In order to try another solution, I have been reading your paper "A Novel Method for Measuring Phase and Group Delay of Mixers Without a Reference Mixer".
In the abstract you wrote this: "This method relies on a VNA system which utilizes *swept-frequency phase-coherent sources and receivers* to maintain a common phase reference."

My second question is: Is my PNA able to perform the measurements made on this paper?

My final question would be: In your paper named "A New Calibration Method for Mixer Delay Measurements that Requires No Calibration Mixer", Is this method based on Option 083 + Power Comb. U9391?

Thank you so much in advance.

All the best,
Pascual

>>我的第一个问题是：这个过滤器是否完全必要？

一般来说，是的，这是必要的。
普通混音器会将+和 - 图像转换为输出，如果不使用滤波器，它们的反射可以重新加入或反相。
过滤器可以防止不需要的产品达到校准标准，因此从整体结果中消除了其影响。
是的，很难使用不同的滤波器，这就是我发明相位参考校准以消除这种需求的原因>>为了尝试另一种解决方案，我一直在阅读你的论文“测量相位和群延迟的新方法”。
没有参考混合器的混合器“。

>是的，确实如此，这也消除了使用过滤器的需要。
此外，如果您的转换器具有许多不同的操作频段，您可以在很宽的频率范围内（使用大量的点）进行单次校准，然后将其应用于许多不同的频段，而不需要为每个频段设置新的校准
或每个新的LO频率。

In general, yes it is necessary.  A normal mixer will convert the + and - image to the output, and if no filter is used, their reflections can add back in or out of phase.  The filter removes the undesired product from hitting the cal standards, and so its effect is removed from the overall result.   Yes, it is difficult to use different filters, which is why I invented the phase-reference cal to eliminate this need

Yes, I believe that it is able to make these measurements, but it will need option 083.

Yes, exactly so, and that also eliminates the need to use a filter. Further, you can do a single calibration over a wide frequency span (use lots of points) and then apply it over many different sets of bands of frequencies if your converter has lots of different bands of operation, without requiring a new cal for each band or each new LO frequency.

好。
因此，在这种情况下，最好的解决方案是获得Opt.083 + Power Comb。
有没有更快的方式获得Power Comb的贷款。
因为我上周发了一封电子邮件给微博客，我还没有收到任何答复。
非常感谢你的支持，Joel博士。
对此，我真的非常感激！
祝福，Pascual

  Ok. So, in this case the best solution would be to get Opt.083+Power Comb.

Is there a faster way to have a loan for the Power Comb.? Because I sent an email to microlease guys last week and I haven't receive any reply yet.

Thank you very much for your support, Dr. Joel. I really appreciate it!

Best wishes,
Pascual
