VISA API的Linux实现
您知道虚拟仪器软件架构的任何Linux实现吗？甚至简单且受限制？首选免费和开源实现。
我所知道的唯一实现是NI VISA，它是非免费且闭源的。此外，它运行在数量非常有限的 Linux 发行版上。例如，我不知道是否可以在 Debian 上运行它。
谢谢。
Do you know any Linux implementations of Virtual Instrument Software Architecture? Even simple and restricted? Free and open-source implementations are preferred.
Only implementation I know is NI VISA which is non-free and closed-source. Moreover, it runs on very limited number of Linux distributions. I don't know whether it is possible to run it on Debian, for instance.
Thanks.

嗯，你需要它做什么？我一直在开发一个纯 Python 仪器库，它可以通过几种不同的协议（串行、VXI-11 (LXI)、GPIB (linux-gpib) 和 PyVISA）进行通信，称为 python-ivi，位于此处：http://www.github.com/alexforencich/python-ivi 。它是对可互换虚拟仪器规范的解释。不过，它不是 VISA，因此如果您特别需要 VISA，它不会为您提供帮助。
它是用 python 3 编写的，并在 Linux 中进行了测试，但它应该是跨平台的，因为它是纯 python。 python-vxi11 中 VXI-11 的实现也是纯 python，因此也应该是跨平台的。
就高级驱动程序和抽象而言，该项目仍处于相对早期的开发阶段，但它基本上完成了 PyVISA 在低级接口方面所做的所有工作。
Well, what do you need it to do? I have been working on a pure Python instrument library that can communicate over several different protocols (serial, VXI-11 (LXI), GPIB (linux-gpib), and PyVISA) called python-ivi, located here: http://www.github.com/alexforencich/python-ivi . It is an interpretation of the Interchangeable Virtual Instruments specification. It's not VISA, though, so if you specifically need VISA, it's not going to help you.
It's written in python 3 and tested in linux, but it should be cross-platform as it is pure python. The implementation of VXI-11 in python-vxi11 is also pure python and therefore should also be cross-platform.
The project is still in relatively early development in terms of the higher-level drivers and abstractions, but it does basically everything PyVISA does for low-level interfacing.
我有同样的问题。谷歌搜索了一下，只得到了 7 年（2005 年）开放签证，我还没有尝试过。
NI VISA 很难与 Debian 和 Ubuntu 配合使用，但我看到有人声称至少在 3.x 之前的内核上取得了成功，例如：

和

祝你好运。我可能会尝试 Open Visa，也许会尝试一下 NI VISA，然后报告是否有效。
I have the same issue. Googling this for a bit only yields the 7 year old (2005) Open Visa which I haven't tried.
NI VISA is tricky to get to work with Debian and Ubuntu, but I have seen post with people claiming success at least for kernels before 3.x see eg:
http://ubuntuforums.org/showthread.php?t=1665036
and

Good luck to you. I will probably try Open Visa and perhaps give NI VISA a shot and report back if it works.
您听说过 PyVisa 吗？它是一个用 Python 编写的开源跨平台 VISA 实现。
http://pyvisa.sourceforge.net/
它似乎依赖于您的 VISA 动态链接库设备
（请参见此处：http://pyvisa.sourceforge.net/vpp43.html #about-the-vpp43-module)
所以它可能无法解决您的问题，但值得一看。
Have you heard of PyVisa? It's an open source, cross-platform VISA implementation written in/for Python.
http://pyvisa.sourceforge.net/
It seems to rely on a VISA dynamically-linked library coming with your equipment
(see here: http://pyvisa.sourceforge.net/vpp43.html#about-the-vpp43-module)
so it may not solve your problem, but it's worth a look.
