查询ENA读带宽功能中的未终止错误

如果在发送bandwidth命令时收到“Query Unterminated”错误，那么我将开始查看上一个命令。
在读取终止字符（ n）之前，读取开始并终止时，通常会抛出该错误。
有没有* OPC？
还是其他没有被回读的东西？
我会逐步完成您的代码并确保错误即将到来。
如果您使用的是任何驱动程序，则可能还需要深入了解其较低级别的代码。



     以下为原文

  If you receive the "Query Unterminated" error when you send the bandwidth command, then I would start looking at the previous command.  That error usually throws when a read was started and terminated before the termination character (n) was read.  Is there a *OPC? or something else that is not being read back?  I would step through your code and make sure the error is coming when you think it is.  If you are using any drivers, it may require digging into their lower level code as well.

同样的错误发生在我身上。
特别是，当找到目标带宽并且查询返回BW，Center，Q和IL时，程序运行正常。
但是当响应不按计划进行时，则找不到目标带宽，而是查询而不是在4个值中返回零，它超时!!!!!!!!!
程序暂停签证超时期限，然后分析仪底部显示“查询未终止”错误。
所以我的程序的快速修复是在发送此查询之前将超时更改为100ms，检索返回的错误“：SYST：ERR？”
然后使用“：DISP：CCL”命令清除显示。
在此之后，您必须再次将超时设置为之前的值（例如5秒）。
安捷伦是否有办法在下次固件更新中解决此问题？
谢谢。

  The same error happens to me.
In particular, the program runs fine when the target bandwidth is found and the query returns the BW, Center, Q and IL fine.
But when the response is not as planned, then the target bandwidth is not found and the query instead of returning zero's in the 4 values it times out!!!!!!!!!
The program halts for the visa timeout period and then "Query Unterminated" error shows on the bottom of the analyzer.
So the quick fix to my program was to change the timeout to 100ms before sending this query, retrieve the error returned with ":SYST:ERR?" and then clearing the display with ":DISP:CCL" command. After this you have to set timeout again to what it was before (e.g. 5sec).

Is there a way that Agilent can fix this problem in the next firmware update?

Thanks.

仪器找不到带宽的时候，我们命令读取会出错？能有办法知道仪器找不到带宽值吗
