At least, until the day before yesterday, my flow graph works fine with USRP
TX: https://picasaweb.google.com/lh/photo/FVqGp6Qt39P3nP-DLzm2pg?feat=directlink RX: https://picasaweb.google.com/lh/photo/rKCvVTq9Ptst_u2Z0TvCDw?feat=directlink Suddenly, however, yesterday received signal strength is much lower than normal TX: https://picasaweb.google.com/lh/photo/Ntw86qudmxB4Qu07Z1TNvQ?feat=directlink RX (normal): https://picasaweb.google.com/lh/photo/H9RItzjpfemHy-OR2eQhQg?feat=directlink RX (abnormal): https://picasaweb.google.com/lh/photo/jJdZIfm6Fd_mGNwu9QRBYQ?feat=directlink It looks like just a noise, but it's a kind of rectangular pulse. (Just, signal strength is similar to noise) RX in normal shows count with about 1k but RX in abnormal? count with just tens How could it happen? I changed nothing but just turning on and off the USRP
