Re: [Discuss-gnuradio] USRP B200 Not Transmitting

[Hasini Abeywickrama]

Hi Derek,

Thank you for suggesting the USRP-users mailing list. I will try that too.

I have tried a simple waveform too and that is not being received too. Yes the TX LED and the RX LED are lit when the flow graphs are running.

I am trying to figure out what the problem might be. Is it necessary to supply power to the USRP B200 when transmitting?

Regards,

Hasini

Hello Hasini,

The USRP-users mailing list is an excellent place to ask such questions.

I do not have experience with the dpsk flowgraphs. Have you verified that you can see a simple sinewave from one B200 to another? uhd_fft and uhd_siggen_gui are excellent tools for testing that. When transmitting with the B200, do you see the TX LED come on and the RX LED on the other one?

Thanks,

Derek

Hi,

I have a USRP B200 set to transmit a signal (using uhd_tx_dpsk.grc in the GNURadio examples) and another USRP B200 receive the signal (using uhd_rx_dpsk.grc in the GNURadio examples). But the receiving USRP does not receive the signal that is being transmitted by the other USRP, even though they are placed very close to each other.

If I user a USRP2 as the transmitter the receiver can receive the signal without any issue.

Can someone please suggest what might be the problem with this. (Please excuse if this is not directly related to GNU Radio)

Cheers

Hasini
