I try to use the function uhd.usrp_source.
It works well with the default rate
parser.add_option("-s", "--samp-rate", type="eng_float", default=1e6,
help="set sample rate (bandwidth) [default=%default]")
But i would like to have a better rate (1e9), and if i change that, it didn't works.
Someone know why?
Thank you a lot!

Requested sample rates from UHD hardware must be proper divisors of the master sampling rate on the hardware. For USRP1/B100/E100, that's 64Msps, and for N2XX it's 100Msps.
Typically, sample rates between master_rate/4 to master_rate/512 are supported.
A sample rate of 1e9 is not a valid sample rate--and seriously 1 Gigasample/second? You really expected your computer to keep up to 1 GigaSample/second?
