DSOX2012A GPIB通信出现错误

嗨Stanislav，虽然GPIB提供比USB更强大的物理连接，但在某些情况下可能会出现问题。
我首先建议您看看是否可以使用USB或LAN连接复制此问题，只是为了查看是否清除它。
此外，如果您使用USB-GPIB适配器（82357B），其某些地址与BenchVue不兼容，因为如果使用串行轮询，适配器将无法正常工作。
避免使用地址9,11,13,25,27和29.如果这不是问题，其他GPIB问题可能与使用Keysight之外的I / O库有关。
尽管NI和Keysight IO可以共存，但除非您拥有NI GPIB硬件，否则有时使用我们的产品会有所帮助。
要排除这种情况，请使用控制面板 - >程序和功能“修改”（而不是“修复”）Keysight IOLS，使Keysight成为“主要”。

  Hi Stanislav,

While GPIB provides a more physically robust connection than USB, it can be problematic in some situations. I would first suggest that you see if you can duplicate this problem using a USB or LAN connection, just to see if that clears it up. Also, if you are using a USB-GPIB adapter (82357B), that has some addresses that do not work well with BenchVue because the adapter does not work correctly if serial poll is used. Avoid addresses 9,11,13,25, 27 and 29.

If that is not the problem, other GPIB issues could be related to using an I/O library other than Keysight's. Although NI and Keysight IO can co-exist, sometimes it helps to use ours unless you have NI GPIB hardware. To rule that out, use Control Panel -> Programs and Features to "Modify" (not "Repair") the Keysight IOLS, making Keysight "Primary".

嗨Brian，只有在GPIB连接的情况下才会出现此问题。
在USB连接期间它没有问题（我们在USB连接中有不同的问题。我们无法从示波器捕获平均数据（正常可以）但这是不同的问题......）。
是的，我们使用USB-GPIB适配器（82357B）。
范围地址为7，只有Keysight IO库安装在计算机中。
感谢您的想法如何解决它。

  Hi Brian,

this problem occures only in case of GPIB connection. During USB connection it is without problem (we have different problem in USB connection. We can not capture averaged data from scope (normal are ok) but this is different problem... ). 

Yes, we use USB-GPIB adapter (82357B). Scope adress is 7 and only Keysight IO library are installed in computer. 

Thank you for your ideas how to solve it.

如果您可以向我们发送监控SCPI总线流量的IO Monitor，我们可能会看到一些东西。
请捕获跟踪并在此处发布或发送至keyight dot com的bv_support。

  If you can send us an IO Monitor trace of the SCPI bus traffic, we might be able to see something. Please capture a trace and post it here or send to bv_support at keysight dot com.

嗨布莱恩，这是日志文件。
谢谢。

我们终于弄清楚这里发生了什么。
对不起，花了这么久！
我们正在向设备发送一个非常长的SCPI字符串。
虽然它不是USB和LAN的问题，但它是GPIB的问题。
由于这个原因，我们在BenchVue中测试了GPIB作用域，这应该会导致SCPI字符串被分成几个“块”。
不幸的是，当Wavegen存在时，代码中存在一个错误，导致它无法正常工作（它认为它是函数生成器而不是作用域，因此告诉它拆分GPIB的标志不会被设置）。
我们将在下一个机会修复这个错误，可能是使用rev 3.5，它将在6月份发布。
您可以使用USB或LAN绕过它。
感谢您将此错误引起我们的注意！

  We finally figured out what's going on here. Sorry it took so long! We are sending a very long SCPI string to the device. While it is not a problem for USB and LAN, it is a problem for GPIB. We have a test for GPIB scopes in BenchVue for this very reason, which is supposed to cause the SCPI string to get split into several "chunks". Unfortunately, when a Wavegen is present, there's a bug in the code that prevents this from working right (it thinks it's a function generator and not a scope, so the flag that tells it to split the GPIB doesn't get set). We will be fixing this bug at the next opportunity, probably with rev 3.5, which will be out in June. You can get around it by using USB or LAN.

Thanks for bringing this bug to our attention!
