[USRP-users] USRP latency problem

Hi, I have an application (written in C++) that periodically transmits and receives fixed-size bursts (N=2000 samples long) in full-duplex mode. To account for TX-RX lattency, I introduced an offset of 4N ticks to the TX timestamp. Though the device is configured to stream in continuous mode, the

Hi, I want to know the actual timestamp of TX and RX signals at the RF antenna. For this I have add/subtract the group delay introduced by digital filters in the TX and the RX paths from the UHD timestamp. Through loopback test, I am able to calculate the aggregate delay, but cannot know the TX de
