Hi, I am doing experiments on two usrp n210. And i am using an external 10MHz function generator to sync the frequency of the two usrp. I connect the TTL output of the function generator to the ref input on the usrp. But i still can see the frequency offset on the received signal. I doubt the function generator is not working. Does anyone have idea about this? Any reply will be appreciated.
