Hello,When I put a signal generator that produces a sinwave at 1Khz and that feeds an USRP Sink with a frequency center at 12MHz for example, I got spurs at +/-32Khz, +/-64KHz and +/-96KHz at the output of my N210 (used with LFTX and LFRX). Whatever the frequency center of the USRP and the frequency of the baseband signal, I have to spurs around -70dBc.Any idea on where it could come from ? Hardware EMC problem ? Digital treatment issue ? How to solve it ?Best regards, Fabien, F4CTZ
