Hi Marcus, Thank you for your reply, What I am aiming ultimately is to estimate the time delay a packet could have when running through the following path: HOST(1) =>[Ethernet]=> USRP(1)[FPGA-DAC-AnalogPath-Antenna] ==> On the air ==> The same path Reversed (USRP(2)) ==> HOST(1) or another HOS

Hello list, = I am a newbie in USRP FPGA programming, I used once Xilinx ISE to execute some VHDL code, generated a bit file to program a Virtex 4, But now in the context of GNU Radio and USRP. I would like to know what are the tools rec
