PNA-X方程式编辑器，内存跟踪奇怪的间歇行为

您好，在使用具有内存跟踪的公式编辑器时，我有一些奇怪的间歇行为。
我使用的是固件A.09.90.09。
从附件中，我有73到75的迹线，它们代表了各种温度下增益的记忆痕迹。
在另一个附件中，我有跟踪76和77，它们是定义为这样的公式编辑器跟踪;
迹线76：Tr73.MEM / Tr74.MEM迹线77：Tr73.MEM / Tr75.MEM在温度循环期间，操作员将选择对应于特定温度的适当迹线（即迹线73至75）并选择“标记”
，'记忆'，'数据 - >记忆'命令。
完成该命令后，显示增量的下一个窗口将使用新结果进行更新。
但是，正如您从附件中看到的那样，每隔一段时间，窗口显示就不会正确更新。
（从青色标记显示均显示-200dB）。
现在这是奇怪的部分。
如果我打印出“增益超过温度增量”窗口，则显示屏会以正确的值更新！
我的技术人员在不同的PNA-X机器上多次观察到这种行为，但当然是间歇性的，所以没有办法可靠地重复这种行为。
而且，有时候，显示器是错误的（即不会总是显示-200dB但可能不同但错误的值）并不明显。
如果有人可以调查这个问题，那将非常感激。
谢谢，rok 04_14_2014-equation edtior没有正确更新.PNG81.2 KB

  Hello,

I am having some strange intermittent behavior when using the equation editor with memory traces. I am using Firmware A.09.90.09.

From the attachment, I have traces 73 to 75 which represent memory traces of the gain at various temperatures.  

In the other attachment, I have trace 76 and 77 which are equation editor traces defined as such;


Trace 76: Tr73.MEM/ Tr74.MEM
Trace 77: Tr73.MEM/Tr75.MEM

During the temperature cycling, the operator would select the appropriate trace corresponding to the particular temperature (i.e. Traces 73 to 75) and select the 'Marker', 'Memory', 'Data -> Memory' command. Upon completion of the command, the next window showing the delta would update with the new results.

However, as you can see from the attachment, every so often, the window display would not update correctly. (as evidenced from the cyan markers all showing -200dB). Now here's the strange part. If I were to print out the 'Gain over Temp Delta' window, the display then updates with the correct values!  

My technicians have observed this behavior on more than 1 occasion on different PNA-X machines, but of course it is intermittent, so there is not set way to reliable repeat this behavior. Also, sometimes, it is not obvious the display is wrong (i.e. won't always show -200dB but may be different but wrong values). If someone can look into the problem, that would be greatly appreciated.

Thanks,
rok
