Ettus Research's USRP (Universal Software Radio Peripheral) enables software-defined radio and was designed by Matt Ettus. USRP performs as an RF front end for a computer that runs the GNU Radio software. It converts radio waves that are picked up via an antenna into digital copies that the computer software can process or convert into a wave synthesized by the computer into a radio transmission. Testing was done with GNU Radio and the USRP together on Linux and Macintosh OS X computers, but the GNU Radio software also operates with other RF front ends and can be used with prerecorded signal samples without any radio hardware. The USRP can also be used with commercial proprietary software, including Matlab and LabView, or with internally written custom code. Many interconnects for hardware and hackers are provided, along with downloadable detailed schematics and Verilog code that configures the field programmable gate array (FPGA). Testers worked for 150 minutes, but without much difficulty, to get a local FM station to play through the speakers of a computer.
