BenchLink Data Logger和34970A扫描时错误

您发送的“下载仪器配置”窗口图中的“ASRL6 :: INSTR”地址表示RS232连接，而不是USB / GPIB。
RS232连接的通信问题相当普遍，遗憾的是由于许多PC中的RS232实现。
你能确保从Benchlink的“Find Instruments”窗​​口使用GPIB连接吗？
您可能首先进入IO库，安捷伦连接专家（ACE）并查看它是否通过USB / GPIB显示与34970A的连接。“查询未终止”是一个SCPI错误，表示查询命令因发送另一个命令而中断
在查询操作完成之前。
如果您有兴趣了解错误的详细信息，可以使用IO Libraries ACE IO监视器捕获配置下载期间的所有IO。



     以下为原文

  The "ASRL6::INSTR" address in the "Downloading Instrument Configuration" window picture you sent indicates an RS232 connection, not USB/GPIB.   Communication problems with RS232 connections are fairly common, unfortunately due to the RS232 implementation in many PCs.  Can you make sure you are using the GPIB connection from the "Find Instruments" window in Benchlink?   You might first go into the IO Libraries, Agilent Connection Expert (ACE) and see if it shows a connection to a 34970A over USB/GPIB.

The "Query Unterminated" is a SCPI error indicating that a query command was interrupted by sending another command before the query operation was complete.   If you are interested in finding out the details of the error, you can use the IO Libraries ACE IO monitor to capture the all the IO during the configuration download.

感谢您的回复.Prologix GPIB-USB转换器设置了一个虚拟串口com，这就是ACE中显示的内容。
我已经尝试过，无法将其显示为GPIB-USB连接。
作为参考，插入34970A的唯一内容是GPIB-USB转换器。我已经附加了IO监视器日志，以了解按下“扫描”按钮时发生的操作。



     以下为原文

  Thanks for your reply.

The Prologix GPIB-USB converter sets up a virtual Serial Port com and that is what shows up in the ACE.  I have tried and can not get it to show up as a GPIB-USB connection.  For reference the only thing plugged into the 34970A is the GPIB-USB converter.

I have attached the IO Monitor log for the actions that take place when the Scan button is pushed.

我发送的IO Monitor日志中看不到任何错误。
我将这个传递给IO专家，看看他是否可以发现任何事情或者知道Prologix USB-GPIB转换器有任何问题。



     以下为原文

  I can't see anything wrong in the IO Monitor log you sent.   I'm passing this on to the IO expert to see if he can spot anything or know of any problems with the Prologix USB-GPIB converter.

有没有办法可以借用像使用GPIB地址的Agilent 82357B这样的USB-GPIB转换器，并尝试一下？



     以下为原文

  Is there any way you can borrow a USB-GPIB converter like the Agilent 82357B, which uses a GPIB address, and try it?

它不会显示为USB / GPIB。
只有Agilent 82357A / B将显示为USB / GPIB。
Prologix GPIB将显示为RS-232。



     以下为原文

  It won't show up as a USB/GPIB. Only the Agilent 82357A/B will show up as USB/GPIB. The Prologix GPIB will show up as RS-232.

刚刚注意到你正在使用XP和Vista的家庭版。
不支持家庭版。
如果那是问题，我认为你甚至无法运行Datalogger软件，但它可能会，并且你可能因此遇到其他问题。



     以下为原文

  Just noticed that you are using the Home Edition of XP and Vista.   Home editions are not supported.  I would think you couldn't even run the Datalogger software if that was the problem, but it could be, and you will likely run into other problems problems because of this.

我做了一些挖掘和使用Prologix适配器，它不能与Benchlink Datalogger软件一起使用。问题如下：您在配置中设置了'自动读后读'但* RST命令（一个）
这是错误的）不是一个查询，所以当Prologix试图查询仪器时，它会出错。
如果禁用“写入后自动读取”，则必须在读取响应之前发送特殊命令“++ read”。
Benchlink数据记录器软件不适用于此。您可以选择使用34970A上的串行端口。
如果您的PC没有任何串行端口，您可以在当地的电子商店购买USB转RS-232适配器几美元。另一种选择是购买Agilent（或NI）GPIB或USB / GPIB适配器。
这些都是经过良好测试，记录和标准的设备.Prologix GPIB适配器有点不同，不适用于大多数预先存在的软件（如果您正在编写自己的软件，您可以使用它，但阅读整本手册
第一）。



     以下为原文

  I did a little digging and playing with the Prologix adapter and it won't work with the Benchlink Datalogger software.

The issue is the following:

You have the 'Auto read after write' set in the configuration but the *RST command (the one that is erroring) isn't a query, so when the Prologix tries to query the instrument, it errors. If you disable 'Auto read after write', you have to send the special command '++read' before reading the response. The Benchlink Datalogger software is NOT going to work with that.

An option for you is to use the serial port on the 34970A. If your PC doesn't have any serial ports, you can buy a USB to RS-232 adapter for a couple of dollars at your local electronics store.

Another option is to buy an Agilent (or NI) GPIB or USB/GPIB adapter. These are well tested, documented and standard devices.

The Prologix GPIB adapters are just a little different and will not work with most pre-existing software (if you are writing your own software you can probably get it to work, but read the whole manual first).

谢谢你的帮助。
我们将看到我们可以提出的替代方案。就使用RS232到USB而言，我们尝试了这一点。
它导致连接非常糟糕，并且在丢失之前无法通信超过一分钟左右。



     以下为原文

  Thanks for your help.  We will see what we can come up with as an alternative.

As far as using a RS232 to USB, we tried this.  It resulted in very poor connections and could not get communication for more than a minute or so before it would drop out.

我不确定你的情况，但是如果你刚购买了这个装置，你仍然可以将它换回34972A。
除了具有USB和LAN而不是RS-232和GPIB之外，它与34970A相同。



     以下为原文

  I'm not sure of your situation, but if you just bought the unit perhaps you can still return it for a 34972A.  It is the same as the 34970A except it has USB and LAN instead of RS-232 and GPIB.
