通过USB从PNA-X到PC的数据传输不能使用局域网

无论用于将PC连接到PNA-X的电缆类型如何，SCPI命令都完全相同。
您可以轻松地从GPIB切换到USB，这取决于您使用的VISA IO接口/库。
在大多数情况下，只需要传递给viOpen（或其环境中的等效方法）方法的地址字符串。
在一种情况下，您发送的字符串以“GPIB [some number] ::”开头，而在另一种情况下，它是一个以“USB [some number] ::”开头的字符串



     以下为原文

  the SCPI commands are exactly the same regardless of the type of cable you use to connect your PC to your PNA-X.  how easily you can switch from GPIB to USB really depends on the VISA IO interface/library you are using.  in most cases it is simply a matter of the address string you pass to the viOpen (or its equivalent in your environment) method.  in one case you are sending a string that starts with "GPIB[some number]::" and in the other case it is a string that starts with "USB[some number]::"

目前我们使用NI（USB）USB到GPIB设备使用NI.488.2驱动程序传输数据。
对于USB，我们需要什么样的驱动程序或库？



     以下为原文

  Currently we are using National Instruments (NI) USB to GPIB device to transfer data using NI.488.2 driver.
For USB what kind of drivers or libraries we will need?

PNA-X后面板上有一个设备侧USB连接器（见下图）。
您只需使用标准USB电缆将PC连接到PNA-X即可。
然后，您可以使用NI MAX应用程序将PNA-X配置为USB仪器。
这是NI网站的_ * link * _，以获取有关如何执行此操作的说明。
将PNA-X配置为USB设备并验证可以与PC通信后，只需更改您使用的VISA资源ID字符串即可使用所有通过SCPI控制PNA-X的现有应用程序
连接到PNA-X。
对于USB仪器，资源ID字符串将如下所示：USB0 :: 2391 :: 11288 :: + [pna-x主机名或IP地址] + :: 0 :: INSTR！https：//dl.dropboxusercontent.com

     以下为原文

  the PNA-X has a device side USB connector on the back panel(see picture below).  all you need is to connect your PC to the PNA-X using a standard USB cable.  you can then use your NI MAX application to configure the PNA-X as a USB instrument.  Here is a _*link*_ to an NI website for directions on how to do that.  Once you have configured the PNA-X as a USB device and verified that you can communicate with it with your PC, you then use all your existing applications that control the PNA-X with SCPI by simply changing the VISA resource ID string that you use to connect to the PNA-X.  for a USB instrument the resource ID string will look something like this:

USB0::2391::11288::+[pna-x hostname or ip address]+::0::INSTR

看起来像NI Max设置错误，我的任何一台PC上都没有NI IO库，所以我无能为力。
至少我会从* IDN中删除“ n”开头？
串。



     以下为原文

  that looks like a NI Max setup error and I don't have the NI IO libraries on any of my PCs, so I can't be much help.  At a minimum I would start by getting rid of the "n" from the *IDN? string.
