The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types (e.g. logic analyzers, oscilloscopes, and many more).

It is licensed under the terms of the GNU GPL, version 3 or later. Design goals and features include:

You can use sigrok to...

  • ...log data from your multimeter
  • ...have a $10 logic analyzer for examining logic circuits
  • ...have a remote GUI for your oscilloscope
  • ...perform measurements on signals
  • ...make sense of digital signals with protocol decoders
  • ...write custom protocol decoders in python
  • ...remote-control your power supply
  • ...remote-control whatever lab device you'd like to support
  • ...write a quick-n-dirty automation tool for your particular needs
  • ...have a framework/frontend for your home-made devices
