-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all, Sorry to bring up painful memories :). I did some calculations to work out frequency drift of the USRPs, and I wanted to know where I'm going wrong. The crystals in the RFX 2400 are spec'ed at 50ppm error, which is to say that the maximum frequency offset between the sender and receiver is then 2 * 50 ppm * 2.462 GHz (802.11b Channel 11) = 246.2 kHz.
I think 50ppm is a total drift of the 64MHz oscillator, so no +/- just 50ppm being the max deviation between two crystals. Brian
