Dear All, I have question about how to create aliasing using USRP. Basically, I have USRP2 with SBX (with recent installations of GnuRadio and UHD). I would like to set the bandwidth of the RF front end to 50 MHz, and use 2MHz of sampling rate (ADC speed). I am using the following command: sudo ./rx_samples_to_file --args addr=192.168.10.2 master_clock_rate=50e6 --freq=2460e6 --bw=50e6 --rate 2e6 --gain=50 --wirefmt sc8 --nsamps 0
Problem: it seems to me that the system (GnuRadio/USRP) observes only 2MHz of RF front end bandwdith. How do I know this? Ans: I compare such settings with the following settings: sudo ./rx_samples_to_file --args addr=192.168.10.2 master_clock_rate=50e6 --freq=2460e6 --bw=50e6 --rate 50e6 --gain=50 --wirefmt sc8 --nsamps 0 The later setting seems to be actual 50 MHz of Rf front end. Any comments and advices on how to create aliasing using USRP are appreciate. Best, Wahhab
