In the lockers located in the classroom 4.3.45 the students have 4 kits USRP1 from Ettus Research. Recently, this company was bought by National Instruments that has expanded the original product line and make all of them compatible with LabView.

The USRP1 kit can be used on various operating systems and the drivers for kit can be found on the following web link from Ettus.

  • GNU Radio - This is an open source software library that supports the USRP1. All the critical functions are implemented in C++ and the construction of the SDR systems is performed in Python.
  • GNU Radio Companion - This is a graphical interface for the GNU Radio with a programming concept similar to Simulink.
  • LabView - Graphical language from National Instruments. You can get a 30days licence from NI. Does not work with USRP1.
  • Simulink - This is an unofficial driver developed at the Karlsruhe Institute of Technology. See below installation instructions. This the most fast way to acquire some data from the USRP1 to Matlab.
