To understand how to set up labrad_tools.

Installing labrad manager. Use scalalabrad

I had to install Java8 to set JAVA_HOME.

Configuring node following wiki from Eric. Cloned it on this repository (copy_SrE.wiki/). serial server added.

sudo systemctl enable labrad-manager.service
sudo systemctl enable labrad-node.service
sudo systemctl enable labrad-web.service

Install scalabrad-web. Following is required for autostart. sudo visudo -f /etc/sudoers

Defaults env_keep += "PYTHONPATH LABRADHOST LABRADNODE LABRADPASSWORD LABRAD_TLS"

This does not make things work. At the end we added Environment=JAVA_HOME=/home/srgang/java/jre1.8.0_361 on [Service] of .service file. Useful commands for debugging

sudo systemctl status labrad-manager.service

This can show what's wrong.

Try to add picoscope server. Following Picoscope in Labrad section.

Install the drivers.

Install lab-modified version of ps3000a.py.

In this case, the path is /usr/local/lib/python3.10/dist-packages/picoscope.

Change udev rule for the picoscope. Using sudo gedit /etc/udev/rules.d/95-pico.rules.

ATTRS{idVendor}=="0ce9", ATTRS{idProduct}=="1213", MODE="0777", GROUP="pico", SYMLINK+="picoscope3403D"

Also, change the permission of the picoscope.

sudo chmod a+rwx /dev/picoscope3403D 

Permission requirement can be checked by trying to run picoscope gui software without sudo.
