Homepage PyPI Python. The programming of measurement instruments can be real pain. For every programming language you want to use, you have to find libraries that support both your device and its bus system. Today VISA is implemented on all significant operating systems. A couple of vendors offer VISA libraries, partly with free download. Python can be used to call functions from a VISA shared library.

VISA and Python Python has a couple of features that make it very interesting for measurement controlling: Python is an easy-to-learn scripting language with short development cycles. It represents a high abstraction level , which perfectly blends with the abstraction level of measurement programs.
How To Control Your Instruments From A Computer: It’s Easier Than You Think
Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi. It only takes a minute to sign up. However, I cannot get it to install on my Pi. You were almost there with your command. After you download the package, run the following command:. If you have no internet access, you will need to solve the dependencies by hand i.
I also strongly suggest you to use virtual environments, which will allow you to work without sudo and without the risk of overwriting packages needed in the system. You may also want to update PIP best to do in virtualenv pip install --upgrade pip. Note, you should probably also install pyserial and pyusb to use connected devices. Sign up to join this community.

Instrument remote control using python (GPIB/LAN/ LAN-GPIB gateway)
Thanks, Harke. Harke Smits Harke Smits 13 1 1 silver badge 7 7 bronze badges. What have you tried thus far? Directories Lib and site-packages exist in right order and place. But can not be found by Python obviously.There was a time when instruments sporting a GPIB connector General Purpose Interface Bus for computer control on their back panels were expensive and exotic devices, unlikely to be found on the bench of a hardware hacker.
The affordable instruments in front of you today may not have a physical GPIB port, but the chances are they will have a USB port or even Ethernet over which you can exert the same control. Surely there must be a way to make your computer talk to it!
We are fortunate in that National Instruments have produced a standard bringing together the various physical protocols and interfaces used, and their VISA Virtual Instrument Software Architecture is available as precompiled libraries for both Windows and Linux x Type the following lines at the command prompt:. You should now be able to test the installation from the Python interpreter.
Make sure the instrument is both turned on and connected via USB, and type the following:. Type the following lines of Python:. ResourceManager ' py' resources.
The first line imports the VISA library, the second loads a resource manager into a variable, and the third queries a list of connected instruments. If all is well, you will see it return a list of resource names for the instruments you have connected. If you only have one instrument it should be similar to the one that follows for our Rigol:.
Hard-coding is not in any way portable as the script may only work with your particular instrument, however it does provide a convenient way to demonstrate the principle in this case. If you are still within the Python interpreter at this point, you can leave it and return to the command prompt by typing a control-D end-of-file character. Assuming all the steps in the previous paragraphs went smoothly, you should now be ready to write your own code.
The first is the PyVISA documentationthe same as we linked to earlier, and the second should be the programming reference for your instrument. The PyVISA manual details all the wrapper functions and has a set of tutorials, while the product manual lists all the commands supported by the instrument. Copy the following code into a text editor, replacing the resource identifier with that of your own instrument, and save it as a. Enable the channel on the instrument — when you are familiar with the API you can do this with your software — and connect it to a signal.
You can then run the script as follows, and if all is well you will be rewarded with the instrument ID string and a voltage reading:. With luck on this page we will have demystified the process of controlling your USB-connected instruments, and you should be emboldened to give it a go yourself.
Really nice for automating parametric sweeps.Pyvisa-py is available on PyPI and can be easily installed using pip:. If you do not install any extra library pyvisa-py will only be able to access tcpip resources. The following sections will describe what extra libraries you need to install and how to configure them to use other resources. Pyvisa-py relies on socket module in the Python Standard Library to interact with the instrument which you do not need to install any extra library to access those resources.
To access serial resources, you should install PySerial. Version 3. No special configuration is required. On all platforms, using GPIB resources requires to install a gpib driver.
On Linux, you can use a commercial driver NI or the linux-gpib project. On Linux, linux-gpib comes with Python bindings so you do not have to install any extra library. Please refer to PyUSB documentation for more details. On Unix system, one may have to modify udev rules to allow non-root access to the device you are trying to connect to.
You can install the latest development version at your own risk directly form GitHub :. PyVISA latest. Using the development version FAQ. You should not have to perform any special configuration after the install.
Read more. For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms. Download the latest Python 3 and Python 2 source. This site hosts the "traditional" implementation of Python nicknamed CPython.
A number of alternative implementations are available as well. Source and binary executables are signed by the release manager or binary builder using their OpenPGP key. Release files for currently supported releases are signed by the following:. Release files for older releases which have now reached end-of-life may have been signed by one of the following:.
You can import a person's public keys from a public keyserver network server you trust by running a command like:. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:. Note that you must use the name of the signature file, and you should use the one that's appropriate to the download you're verifying.
