34972A停止响应

每30秒记录一次34972A（通过USB连接）上4个通道的电压读数的程序（VEE ver.9.31）可以正常工作一两天，但之后会失去与仪器的联系。
与另一台PC上的.vxe文件的行为相同，只安装了运行时引擎。
记录的数据存储在.txt文件中。
这是唯一连接的仪器。
当这个故障发生时，它可以被连接专家看到 - 我可以从控制面板上随意互动。
但VEE表现得好像34972A改变了其Visa别名或者USB线已经掉线等等。我不得不重启.vee / .vxe程序。
有一次故障情况更糟 - 连连接专家都看不到34972A，我不得不重新启动它。
但是我没有在2014年3月17日上午7:17重新启动VEEEdited：Kevin001



     以下为原文

  A program (VEE ver.9.31) which logs voltage readings from 4 channels on a 34972A (connected via USB) every 30 seconds works OK for a day or two but then loses contact with the instrument.  

Behaves the same with a .vxe file on another PC, on which only the runtime engine is installed.

The logged data are stored in a .txt file.

This is the only instrument connected.

When this fault occurs it can be seen by connection expert - and I can interact as I please from the control panel. But VEE behaves as though the 34972A had changed its Visa alias or that the USB cable has fallen out etc. I had to restart the .vee/.vxe program.

On one occasion the fault was worse - even connection expert couldn't see the 34972A and I had to power cycle it. But I didn't have to restart VEE
