caenhv

🤔 What is this?

This is an unofficial Python package to interface with CAEN high voltage power supplies over USB (RS232 protocol).

⚠️ Disclaimer

The features of this package are based on my needs at the time of writing. I have done very limited testing on a single model (DT1471ET) but it should also work for other CAEN power supplies also supporting RS232.

If you use this package, it is very possible you find a bug or some oversight. You are encouraged to make a pull request or to create an issue to report a bug, to request additional features or to suggest improvements.

⚙️ Installation

Installation via pip is supported. To install the latest published version, run:

pip install caenhv

To install the package from source, including test dependencies, clone the repository and run:

pip install .[test]

👨‍💻 Usage

from caenhv import CaenHV

# automatically detect serial port and baudrate (can be manually set)
caen = CaenHV()
# get the first module. CAEN supports multiple modules over the same connection
# typically only one module should be present
module = caen[0]

# get channel number 2
channel = module.channel(2)

# print current 'vset' and 'vmon' values
print(f"vset: {channel.vset}")
print(f"vmon: {channel.vmon}")

# switch channel off and off
channel.off()
channel.on()

# set a new value of 'vset'
channel.vset = 300.0  # 300 V
