I have no clue why you couldn't capture up and downlink with two separate RX daughter boards on USRP1. The USRP2 ADC does complex sampling at 100mhz, so it can capture a 100mhz bandpass. It can't cram that much over the ethernet but someone could create a FPGA image that grabs two 10mhz windows separated by the 90mhz offset. I don't know if any of the existing daughter boards have a bandpass that wide. _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
