Output power analysis of a software defined radio device
Résumé
Universal Software Radio Peripheral (USRP) and GNU Radio are well known Software Defined Radio (SDR) tools. The USRPs designed by Ettus Research are used without a deep knowledge of their performances. In this paper, we report our output power measurements using a USRP B210 driven by a GNU Radio program. Our results show that the obtained output power decreases as the selected central frequency increases. We unveiled the impact of USRP Hardware Driver (UHD) of the GNU Radio on output power of a USRP B210.
