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
When I run benchmark_tx/rx.py, however,
I can see ‘dots’ representing a signal is transmitted on a transmitter
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])
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?
- Wrong frequency option (either tx or rx)
- Wrong/Unspecified sample rate option (either tx or rx)
- Too weak signal strength to catch
