PyVisa | Trouble I identifying Resources | Rigol DS1054 | Keithly 2200-20-5

dustin1986

Hi I am new to automating lab equipment. I am playing around with an oscope and psu to learn. I am using the usb connections. I am using Manjaro linux. I have the usbtmc driver installed and working. My linux box does see the instruments when I plug them in. However, pyvisa doesnot seem to find them. I just get a long list of ASRL "devices" no way to identify which one is the hardware I attached.

Does pyvisa not see the hardware or is thee another way to find devices?

  • You need to create a udev rule for USBTMC devices.

    echo 'SUBSYSTEM=="usb", MODE="0666", GROUP="usbusers"' >> 99-com.rules sudo mv 99-com.rules /etc/udev/rules.d/99-com.rules

    Make sure you're in "usbusers" and do a reboot after that. (And really, reboot. I'm not certain what service has to restart to make it work.) pyVISA may be able to see them then.

    Also, the license for R&S's VISA driver is not very restrictive. My interpretation is that you can use it with anyone's hardware/software. I also know they use pyVISA quite a bit, so it works really well with pyVISA. There are builds for various linux versions on their site.

    Also also, "python-usbtmc" (via pip) can give you some troubleshooting information.
