This contains codes to connect, control and log the output of Keithley SMU devices using python. It contains codes for the following modes and devices
Constant source current Constant source voltage
Keithley 2400 Keithley 2450 Keithley 2657A
| Package | Purpose |
|---|---|
| PyVISA | Connection to Keithley 2450, 2657A |
| PyMeasure | Connection to Keithley 2400 |
| Pandas | Data logging of sourced current/voltage |
The VIAS resource name which the device is connected to needs to be specified. This can be obtained from LABVIEW. Alternatively, they can be found by running the following codes (if PyVISA is installed)
import pyvisa
rm = pyvisa.ResourceManager()
rm.list_resources()
