PyPi Release Downloads Build Status

Warning: Keithleygui v1.1.4 is the last release that is developed and tested for Python 2.7. Newer releases require Python 3.6 or higher.

keithleygui

A high-level user interface for Keithley 2600 series instruments which allows the user to configure, record and save voltage sweeps such as transfer and output measurements. Since there typically is no need to provide a live stream of readings from the Keithley, the data from an IV-curve is buffered locally on the instrument and only transferred to CustomXepr after completion of a measurement.

keithleygui build on the Python driver provided by keithley2600.

Installation

Install the stable version from PyPI by running

$ pip install keithleygui

Or install the latest development version from GitHub:

$ pip install git+https://github.com/OE-FET/keithleygui

Usage

In the terminal, run keithleygui to start the user interface. If your provide the --verbose option, log output showing the communication with the Keithley will be printed to the console.

To start the user interface in a running Python terminal:

from PyQt5 import QtWidgets
from keithleygui import KeithleyGuiApp

app = QtWidgets.QApplication([])

keithley_gui = KeithleyGuiApp()
keithley_gui.show()
app.exec()

You can optionally provide an existing Keithley2600 instance to be used by the GUI:

from PyQt5 import QtWidgets
from keithley2600 import Keithley2600
from keithleygui import KeithleyGuiApp

app = QtWidgets.QApplication([])

keithley = Keithley2600('visa_address')
keithley_gui = KeithleyGuiApp(keithley)
keithley_gui.show()
app.exec()

System requirements

  • Linux or macOS
  • Python 3.6 or higher

Acknowledgements

  • Config modules are based on the implementation from Spyder.
  • Scientific spin boxes are taken from qudi.
