运行N5244A PNA-X固件A.09.90.01得到了尖锐

您可以通过执行以下操作编写一个小宏来“更新”IMD校准：“打开IMD频道上的Rx调平”“打开'更新源功率校准与rx电平偏移'”“”扫描“”关闭Rx
在IMD频道上练级“。
这将获得适当的功率设置。
它们可能只在通道中设置，而不是在calset中设置，所以如果你不应用然后重新应用calset，你必须再次执行它。
并且，当你这样做时，如果你在（功率计头部）的端口上有负载会很好。



     以下为原文

  You can write a little macro to "update" the IMD cal by doing the following:

"Turn on Rx leveling on IMD channels"
"turn on 'update source power cal with rx level offsets' "
"take a sweep"
"turn off Rx leveling on IMD channels".  

This gets the proper power set. They might only be set in the channel, however, not the calset, so if you unapply then re-apply the calset, you have to do it again.

And, it would be good if you had a load on the port (of the power meter head) when you did this.

和p.s。;
rx练级修复了这个问题吗？

  and p.s.; did rx leveling fix the issue?

很抱歉继续询问更多信息，但我发现真正的问题似乎不是平稳的电源（电源主显示小尖峰），这将导致IMD变化高达3倍。
你可以重新发布Cal All的情节，但是这次把PowerMainHi，PowerMainLo和PwrInHi和PwrInLo一起放了吗？
我想知道输入和输出功率是否均为平坦。
有时我看到这个错误，因为它们是输入功率的一些限制。
通常情况下，Rx调平应该会使功率变平，因此看到Rx调平时的任何尖峰都是奇怪的。
这可能只是两个来源中的一个，这就是为什么我想看到个人的高权力和低权力。
有没有机会你也可以保存一个csa文件并发布，或通过电子邮件发送给我。
如果你能提醒我你的固件版本。
最近Cal All有一些小的变化，可能会产生一些影响。
我们可以检查calset，看看这些区域中的某些错误术语是否有些奇怪。

  sorry to keep asking for more information, but I see that it appears the real problem is not smooth power (power main shows small spikes) which will cause the IMD to vary up to 3x as much.

Can you repost the plots of the Cal All, but this time put up PowerMainHi, PowerMainLo, along with PwrInHi and PwrInLo?

I want to see if the input and output power are each flat.  Sometimes I've seen this error when their is some limitation of the inputput power.  Normally, Rx leveling should flatten the power so seeing any spikyness with Rx leveling on is odd.  This might be on only one of the two sources, which is why I want to see the individual high and lo powers.  

Is there any chance you can also save a csa file and post that, or email it to me.  And if you can remind me of your firmware revision.  There were some small changes recently to Cal All that might have some effect.  We can inspect the calset to see if some of the error terms look odd in those regions.

我想知道是否已经执行了具有独立源和频谱分析仪的相关性测试......实际数字是什么？
我们和我们的客户仍然希望看到固定频率的C / 3IM测量值.....

  I am wondering if a correlation test, with separate sources and spectrum analyzer, has been performed... whats the real number?

We, and our customers, still prefer to see fixed frequency C/3IM measurements.....
