I'm currently testing UHD. I use two USRPs with one SBX on each. and I got GNU Radio 3.5.0rc0 on Ubuntu 10.10 and benchmark programs supporting UHD.
When I run benchmark_tx/rx.py, however, tx@ubuntu $ ./benchmark_tx.py -f 410M rx@ubuntu $ ./benchmark_rx.py -f 410M I can see 'dots' representing a signal is transmitted on a transmitter side. but a receiver does give nothing on a screen. and the screens on the both side, I got this message. ==================================================== No gain specified. Setting gain to 5.750000 (from [-20.000000, 31.500000]) UHD Warning: The hardware does not support the requested TX/RX sample rate: Target sample rate: 0.050000 MSps Actual sample rate: 0.250000 MSps Symbol Rate: 25000.000000 Requested sps: 2.000000 Given sample rate: 250000.000000 Actual sps for rate: 10.000000 Requested sample rate: 50000.000000 Actual sample rate: 250000.000000 ==================================================== What did I do wrong? 1. Wrong frequency option (either tx or rx) 2. Wrong/Unspecified sample rate option (either tx or rx) 3. Too weak signal strength to catch 4.
