[Discuss-gnuradio] sending single tone Am modulated using usrp1+wbx

[José María Valencia]

Hi, I want to transmit and receive a 1kHz cosine tone using dsb am modulation and usrp1 with 2 wbx dbs, I have connected from  tx/rx output  wbx-a to rx2 input wbx-b with a 50ohm sma cable, I’m expecting in scope sink the cosine tone with 1KHz but I have another signal, can you tell me what could be the error?

I’m based on the complex envelope theory:   I=Ac(1+m(t))    Q=0

You can see the diagram and the signals on the attached image.

Thanks.
