我正在尝试使用上述设备构建系统,我正在尝试使用NI的NIMax软件和National Instruments GPIB-USB-HS连接器向HP8350B发送命令。
该软件识别出网络分析仪的存在,并意识到它具有必要的两个端口; 16和17为passthrough。 但是,我无法通过直通地址向清道夫发送任何指示。 每次我这样做,分析器告诉我Data PassThrough(是)执行,但系统只是超时而没有任何反应。 有谁知道我能做些什么来解决这个问题? ETA抱歉,这是一个8757C,而不是B.标题已更改为accountEdited:Donalbain于2014年1月17日上午3:59 以上来自于谷歌翻译 以下为原文 I am trying to build a system using the above set of equipment, and I am trying to send commands to the HP8350B using the NIMax software from National Instruments and a National Instruments GPIB - USB - HS connector. The software recognises the existence of the network analyzer, and realises it has the necessary two ports; 16 along with 17 for the passthrough. However, I am unable to send any instructions through the passthrough address to the sweeper. Every time I do it, the Analyzer tells me that Data PassThrough (is) Executing, but then the system simply times out and nothing happens. Does anyone have any idea what I can do to fix this? ETA Sorry, it is an 8757C, not B. Title changed to account Edited by: Donalbain on Jan 17, 2014 3:59 AM |

我不确定是不是这样,但是在向扫地机发送命令后(在地址17处),你必须*然后向8757(在地址16处)发送一个命令,以便退出passthough模式。
你累了吗? 扫地机是否正确响应了您的命令? 以上来自于谷歌翻译 以下为原文 I'm not sure if this is it, but after sending a command to the sweeper (at addr 17), you *must* then send a command to the 8757 (at addrs 16) in order to exit the passthough mode. Have you tired this? And did the sweeper respond to your command properly? |

不..扫地机不响应我发送的任何命令。 以上来自于谷歌翻译 以下为原文 No.. the sweeper does not respond to any commands that I send it. |

8757具有环回GPIB测试。 尝试运行它以查看是否可以正确读写。 如果这个过去了,那么我会专注于8350.当然,这假设电缆是好的! 如有必要,请参阅服务手册。 这不可能那么复杂。 如果这些都不起作用,那么我将专注于您的软件/适配器中使用的语法和终止字符。 对不起,我对NI的东西一无所知。 哦......还有一件事要记住,...... 8757(和8350)可能挂在今天的快速电脑上。 该接口是在CPU以1 MHz运行时设计的。 尝试在发送命令时添加延迟。 以上来自于谷歌翻译 以下为原文 The 8757 has a loopback GPIB test. Try running that to see if can properly read and write. If that passes, then I would concentrate on the 8350. Of course, this assumes the cable is good! See the service manual if necessary. This can't be that complex. If none of this works then I would concentrate on the syntax and termination characters used in your software/adapter. Sorry, I know nothing about NI stuff. Oh...one more thing to remember,....the 8757 (and 8350) may hang on today's fast computers. This interface was designed when CPUs were running at 1 MHz. Try adding delays to the sending of commands. |
