Alex, You are right. "Auto T/R" is the right option to use. One little thing, the usrp source/sink block takes a parameter "gain(db)", what is the maximum value that I can specify here? Is it 32db? Also, what maximum amplitude value I can specify in signal source block? Is it 32767?
Thanks. ________________________________________ From: Alexandru Csete [oz9...@googlemail.com] Sent: 12 July 2010 11:13 To: Rahman, Muhammad Mahboob Ur Cc: discuss-gnuradio Subject: Re: [Discuss-gnuradio] transceiving a sinusoid using usrp's On 12 July 2010 15:52, Rahman, Muhammad Mahboob Ur <mahboob-rah...@uiowa.edu> wrote: >... > And when I stop the simulation on tx computer, a sinusoid waveform of > frequency about 4.4 KHz is displayed on rx computer.

This happens if you have the Transmit parameter of the USRP sink set to "Enable". If you use "Auto T/R" the transmitter will stop when the program stops.
