@sean can you please tell me how you got minimum sampling rate for usrp N210 as 100*e6/512. I know that the sampling rate should be 100*e6/N where N is an integer. So N can be any integer even greater than 512 right. In that way, what is the minimum that the USRP accepts. what is maximum N that can be used.

The minimum "reasonable" sample rate I've used is 2e5 (100e6/2e5 = 500). I think 100e6/512 = 195312.5 is the smallest supported rate.

Yup, sorry, you're right.  I tend to pick values that are valid for both 64Msps and 100Msps master clock rates, since I write apps that need to be reasonably
  agnostic with respect to hardware.


Ah, makes sense.
