hvps 0.0.5

An unofficial Python package 🐍📦 to interface with CAEN high voltage power supplies

HVPS

🤔 What is this?

The goal of this Python package is to interface with different brands of high voltage power supplies in a uniform way. Currently only CAEN and iseg brands are supported. Communication is performed via serial port (over USB).

⚠️ 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 hvps

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

pip install .[dev]

👨‍💻 Usage

CAEN

from hvps import Caen

# automatically detect serial port and baudrate (can be manually set)
caen = Caen()
# get the first module. CAEN supports multiple modules over the same connection
# typically only one module will be present
module = caen.module(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 on
channel.turn_off()
channel.turn_on()

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