Hi Ekko,

The sample rate has to be some fraction of the clock rate divided by an integer. The clock rate on the E310 defaults to 32MHz I believe, so 32MHz divided by 4 gives you 8 Msps. The system will get you as close as it can to the desired sample rate. You can set the clock rate to something else to achieve the 10 Msps rate that you want (try setting it to 30MHz).

when i set the uhd_sink or uhd_source samp rate to 10M
i got that 
The hardware does not support the requested TX sample rate:
    Target sample rate:10.000000 MSps
    Actual sample rate: 8.000000 MSps
then i set it to other value,some of them is ok,some not,
i know that the max samp rate of e310 is not 8M
so i want to know what value is ok for the uhd_sink or uhd_source 
between the min to max samp rate. 

i do not find it on manual page,but i got this message.

thank you
