Chandu, Please read through the USRP FAQ and take a look at the pages below. If you've still got a question after reading this stuff ask again. In particular look at usrp_standard_rx::set_mux http://gnuradio.org/redmine/wiki/gnuradio/UsrpRfxDiagrams http://gnuradio.org/redmine/attachments/129/USRP_Documentation.pdf http://gnuradio.org/doc/doxygen/classusrp__basic__rx.html http://gnuradio.org/doc/doxygen/classusrp__standard__rx.html Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
