Hi Matt, I recently learn the uhd project which contain a double type timestamp in band signaling. I want to know if this change really take a more precise timestamp from usrp hardware or it just an interface change to meet other hardware? For now, I want to measure the time of flight to count a distance, so the timestamp should be as precise as at least 100ns to meet my need.
The UHD will give you sample times which are accurate to 1 cycle. On the USRP2 this is 10ns.
