[Discuss-gnuradio] Quick question on UHD and USRP1

2011-05-20 Thread Colby Boyer
Hey Guys, It seems that the USRP1 out with UHD is normalized to 1.0, vs some big number as with the old USRP drivers. I assume this is correct? Otherwise my cards are not kicking out any RF power. --Colby ___ Discuss-gnuradio mailing list Discuss-gnura

[Discuss-gnuradio] USRP2 slave PPS signal over the MIMO cable

2011-05-20 Thread David Scaperoth
I would like to run two USRP2's as master and slave, and I would like to only use a 1PPS on the master (each USRP2 would be controlled by two separate processes). When I run the test_pps_input on the slave, the program fails. However, the master is able to find the PPS just fine. I've tried a co

Hi Adib, I read your publications on gnuradio. What method did you use to sense the spectrum? How could you achieve that sensing time, 0.xx ms? I searched the forum for spectrum sense but find no explanation for slow sensing. Is there any other sensing methods applicable to gnuradio? The logic
