Hi,
Thanks for reading my mail. I would like to ask is there any
additional setup or configuration required to execute benchmark_tx.py
and benchmark_rx.py?
My problem is I tried to initiate simple communication between two
USRP1 using benchmark_rx.py and benchmark_tx.py . I had browse through
the mailing list looking on how to use the file appropriately. Running
benchmark_tx.py also execute help which I follow closely but failed to
receive any packets. If I tried to execute at transmitter:
benchmark_tx.py -f 400M -S 10
and at receiver
benchmark_rx.py -f 400M -S 10
I did not received packet status. I only received '0' in the terminal.
Is it correspond to error?
I also read mailing list sent by other members but none mentioned
about not able to execute benchmark_tx.py . If I missed any post,
could anyone please provide me the link.
For additional information:
Gnuradio version used: v3.5.0rc0
USRP1 : revision 4
Ubuntu: 11.10
Daugtherboard: SBX
Please let me know if I had to provide any additional information.

You're asking for 10 samples per symbol, which may exceed the rate at
which your receiver computer can keep up, depending on
the modulation used, and the complexity of the modulation
techniques. Are you using the narrowband or ofdm examples?
The 'O' means overrun. The hardware (USRP1) is sending samples faster
than your computer can keep up.
