Hi, Has anyone used 2 USRPs to simultaneously receive 4 different frequencies using DBSRX cards? I just wanted to check the correct way of linking it all up. As I understand it the correct combination is:
fg=gr.flow_graph() u0=usrp.source_c(0,decim,2,0,0) u1=usrp.source_c(1,decim,2,0,0) u0.set_mux(0x00003210) u1.set_mux(0x00003210) tune_result0=usrp.tune(u0,0,usrp.selected_subdev(u,(0,0)),freq0) tune_result1=usrp.tune(u0,1,(1,0),freq1) tune_result2=usrp.tune(u1,0,(0,0),freq2) tune_result3=usrp.tune(u1,1,(1,0),freq3) de_inter0 = gr.deinterleave(gr.sizeof_gr_complex) de_inter1 = gr.deinterleave(gr.sizeof_gr_complex) fg.connect(u0,de_inter0) fg.connect((de_inter0,0), ...) fg.connect((de_inter0,1), ...) fg.connect(u1,de_inter1) fg.connect((de_inter1,0), ...) fg.connect((de_inter1,1), ...) Is the mux correct for this? Or do I need to do something else to ensure the correct DDC works on the correct channel?
