摘要

In this paper, we report a series of RF (Radio Frequency) measurements performed on a USRP and a GNU Radio Software Defined Radio (SDR). The RFX 900 and RFX 2400 Daughter Boards are connected to an USRP N210 platform and driven by the GNU Radio open source software. We focused on two main aspects: the output RF bandwidth and the power linearity versus the DAC value for each daughter board. The measured bandwidths of the daughter boards are found smaller than advertised while the linearity of the output power with the expected results is in good agreement only for low DAC values.
