转换器测量（NFx，GCX，IMDx）校准数据编程

问答对人有帮助，内容完整，我也想知道答案 0 是否有与SENS相同的命令：CORR：CSET：DATA用于转换器测量？据我所知，该命令控制着传统PNA测量的12项误差项。有没有办法可以为转换器测量设置所有必需的校准数据？是否有转换器测量所需的所有校准项列表？我想为NFx，IMDx，GCX和SMC +相位测量建立我自己的校准集。谢谢！艾伦以上来自于谷歌翻译以下为原文 Is there an equivalent command to SENS:CORR:CSET:DATA for converter measurements? That command, as I understand it, controls the 12-term error terms for traditional PNA measurements. Is there a way I can set ALL the required cal data for converter measurements? Is there a list of all the required cal terms for converter measurements? I would like to build my own calset for NFx, IMDx, GCX, and SMC+Phase measurements. Thanks! Alan 0

答案对人有帮助，有参考价值 0 看看命令“CSET：ETERm：CATalog？” 和“CSET：ETERm [：DATA]”命令。使用这些命令，您可以获取现有的校准集，并获取其所有eterms的列表以及每个错误术语的拉/放数据。话虽如此，从头开始构建应用程序通道（SMC，GCX，NFX，...）的校准集并不是我们向普通用户推荐的。将坏数据放入calset或创建格式错误的calset非常容易，当你尝试应用它时会导致问题。有些没有其他的复杂，但所有应用程序通道校准集的误差项超出了传统上用于校正S参数测量的标准12项模型。虽然12期模型是众所周知且文档齐全的，但我们为这些应用程序创建的附加错误术语对于Keysight来说是独一无二的，并且没有很多关于它们的公开信息。在你所表达的所有兴趣中，Noise Figure是迄今为止最复杂的。对于该校准，我们实际上测量了接收器的噪声参数，并且该过程不容易手动复制。在尝试构建自己的校准集之前需要注意的另一件事是，校准集不仅包含误差项，还包含用于校准的通道的激励条件。没有用于更改校准集中的激励数据的远程命令。唯一可行的方法是在实际通道上进行虚拟校准，然后获取生成的校准集并使用上面的命令对其进行修改。祝你好运以上来自于谷歌翻译以下为原文 look at the commands "CSET:ETERm:CATalog?" and "CSET:ETERm[:DATA]" commands. with these commands, you can take an existing calset, and get a list of all its eterms and pull/put data for each of these error terms. That being said, building calsets for application channels (SMC, GCX, NFX, ...) from scratch is not something we would recommend to the average user. it is very easy to put bad data into a calset or create a malformed calset that will cause problems when you try to apply it. some are less complicated than the others, but all the application channel calsets have error terms that go beyond the standard 12-term models that people use traditionally for correcting S-Parameter measurements. while the 12-term models are well known and well documented, the additional error terms that we have created for these applications are unique to Keysight and there is not a lot of public information about them. Of all the ones you have expressed interest in, Noise Figure is by far the most complicated. for that calibration we actually measure the noise parameters of our receiver and that process is not easily replicated manually. the other thing that you need to be aware of before attempting to build your own calsets, is that calsets don't just contain the error terms, they also contain the stimulus conditions of the channel used for the calibration. there are no remote commands for changing the stimulus data in the calset. the only way you can do it is to do a dummy calibration on your actual channel, and then take the resulting calset and modify it using the commands above. Best of luck
