This package enables current-voltage (source-measure) measurements using the four-point method. It employs a GPIB-USB-HS controller device and a 2450 SourceMeter. Figure 1 illustrates the experimental setup.

Installation
- Python 3.12.5
- Install dependencies: pip install -r requirements.txt
- Jupyter Notebook: pip install notebook
- GPIB-USB-HS
- NI-VISA
It is important to ensure that the drivers are compatible with your operating system in steps 4 and 5. Refer to the manufacturer’s guides. We used Windows 10 with version 17.0 of the driver and NI-VISA software.
