I have recently purchased the USRP board and the RX daughterboard, and I have started working on them. One major factor that I need to change is the sampling rate frequency of the ADCs on USRP, I know the USRP clock is at 64MSPS and I need to reduce it to at least half of it. My question is two fold, should I decimate the digitization, or is there any other way of doing that? How difficult would be to change the clock? And can someone confirm that the USRP can accept an external clock? If yes do I need to have some hardware adjustments?

Please excuse me if I repeat an older thread, it would be nice to guide me there. I think that it might could be a good idea to have some kind of forum, with different parts dedicated to USRP.
