channel.single方法并不总是完成扫描

您好，我正在使用2端口E8362C，运行固件版本，A.09.42.22。
使用DCOM。
我注意到Channel.Single（bWait：= True）并不总是完成扫描。
它有时会在扫描结束时留下几个点，未扫描 - 与之前的扫描相同。
如果我关闭电源，扫描，然后打开电源，然后再次扫描，则尤其明显。
最后的几个点在关闭电源的情况下保持不变。
我可以使用前面板控件以及使用DCOM对象模型重现问题。
此外，我尝试了Channel.Single（bWait：= False），然后循环直到Channel.IsHold = True，但我得到了完全相同的结果。
在任何一种情况下，如果我再扫一次，那么扫描就完成了。
另一个奇怪的事情是并非所有迹线都受到影响，我只运行一个通道，所有测量都在同一个通道上。
我还注意到，如果我移除Tr7，那个带有等式的那个，那么问题就会消失。
我还附上了一个.csa文件。
请参阅随附的屏幕图片。
有什么想法吗？
这是不幸的，因为我现在必须多次扫描以确保我完全扫除......请帮忙。
谢谢Andy（请参阅随附的屏幕图片）编辑：andeezlemoyo于2015年5月4日下午8:27 Capture9.PNG135.6 KB

  Hello,

I am working with an 2-port E8362C, running firmware version, A.09.42.22. Using DCOM.

I have noticed that Channel.Single(bWait:=True) does not always finish sweeping.  It sometimes leaves a few points at the end of the sweep, unswept--unchanged from the previous sweep.  It is especially noticeable if I turn off power, sweep, then turn on power, then sweep again. The few points at the end remain unchanged from the sweep with the power off.  

I can reproduce the problem with the front panel controls as well as using the DCOM object model.

Also, I've tried Channel.Single(bWait:=False) and then looping until Channel.IsHold = True, but I get the exact same result.

In either case, if I sweep a second time, then the sweep is completed.   

Another odd thing is that not all of the traces are affected, I'm running a single channel only, all measurements are on the same channel.

I also notice that if I remove the Tr7, the one with the equation, then the problem goes away.  I've also attached a .csa file.

Please see attached screen pic.

Any thoughts?  This is unfortunate as I have to sweep multiple times now to make sure I get a full sweep...

Please help.

Thank you,

Andy
