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,

What sample rate? (Does that change things). Also, if you reduce the
baseband amplitude a bit, does that help?
