Agilent IO库的用途是什么

串口和USB非常不同。
USB具有固有协议，数据以数据包形式发送，带有确认等。假设您正在通过PC控制示波器，是的，您需要/想要Agilent I / O库以及pyvisa。
您需要打开连接，如文件，发送赞扬，并等待响应。
VISA库有助于此。
如果需要，您甚至可以使用串行连接。
以下是我所处的Python代码中的一些部分。
scope = instrument（“TCPIP0 :: 156.140.157.107 :: inst0 :: INSTR”） - 这将打开与作用域的连接。
引用的字符串告诉VISA如何谈论范围。
I / O库将识别范围，并为您提供此字符串，以便您可以将其复制并粘贴到程序中。
scope.write（“WAV：SOUR CHAN1”） - 只是其中一个设置命令。
data = scope.ask（“：WAVEFORM：DATA？”） - 询问数据范围并将数据转储到数组中（实际上是一个元组）祝你好运！

  Serial ports and USB are very different. USB has an inherent protocol, and data gets sent in packets, with acknowledgements, etc.

Assuming you are controlling the scope from a PC, yes, you need/want the Agilent I/O Libraries, along with pyvisa. You need to open the connection, like a file, send commends, and wait for responses. The VISA libraries help with that. You can even use them with a serial connection if you want. Here are some pieces from some Python code I had lying around.

scope = instrument("TCPIP0::156.140.157.107::inst0::INSTR")
- This opens the connection to the scope. The quoted string tells VISA how to talk the scope. The I/O Libraries will identify the scope, and give you this string, so you can copy and paste it into your program.

scope.write("WAV:SOUR CHAN1")
- Just one of the setup commands.

data = scope.ask(":WAVEFORM:DATA?")
- ask the scope for data and dump the data into an array (actually a tuple)

Good Luck!

嗨，谢谢你的支持。
我可以与DSO沟通。
在PyVISA 1.5中这个变化不大..进口签证;
resMan = visa.ResourceManager（）;
res = resMan.list_resources（）;
temp =''+ join（res）;
temp1 = temp.encode（'utf-8'）;
dsoObj = resMan.get_instrument（temp1）;
打印（dsoObj.ask（ “* IDN？”））。
从文档我发现，PyVISA使用visa32.dll访问VISA。
我不确定访问Agilent IO库的位置？
但由于安捷伦IO库，我有一个名为Agilent Connection Manager的应用程序，因为我可以连接到仪器并调试状态。
是否真的需要使用pyVISA与仪器进行通信。
我不是软件工程师，我最讨人喜欢..

  Hi,

Thank you for support.

I can able to communicate with the DSO.

in PyVISA 1.5 this is little changed..
import visa;
resMan = visa.ResourceManager();
res = resMan.list_resources();
temp = ''+join(res);
temp1 = temp.encode('utf-8');

dsoObj = resMan.get_instrument(temp1);

print(dsoObj.ask("*IDN?")).

from documentation i found that, PyVISA uses visa32.dll for accessing VISA. 
I am not sure where Agilent IO libraries are accessed ?
But because of Agilent IO libraries i have one application called Agilent Connection Manager because of that i can connect to the instrument and debug the status.

Is really Agilent IO libraries are required pyVISA to communicate with the instrument. I am not a software engineer, i am hobbiest..

I / O库不是必需的。
他们只是让事情变得容易多了。
当您有一个想要与之交谈的设备时，您的示例很有效。
当有许多设备，并且您正在尝试调试代码时，I / O库提供了许多有用的功能，例如自动设备发现和交互式I / O.
如果您想扩展使用仪器和远程控制的知识，请深入了解I / O库，然后是Command Expert，然后是BenchVue，所有这些都是免费工具。

     以下为原文

  The I/O Libraries are not required. They just make things a lot easier. Your example works well when you have a single device that you want to talk to. When there are many devices, and you are trying to debug your code, the I/O Libraries provide a lot of useful functionality, such as automatic device discovery, and interactive I/O.

If you want to expand your knowledge of using instruments and remote control, look deeper into the I/O Libraries, then Command Expert, then BenchVue, all of which are free tools.

谢谢.......我会尝试看IO库......

  Thank you.......

I will try to see IO libraries......
