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 delay and the RX delay separately. The UHD driver has APIs to get the list of filters used in the signal paths. But my calculated values do not match with the loopback delay I measured. Could someone help me with this? I am using USRPB200 set with 30.72 MHz master clock rate and 1.92 MHz sampling rate.
Regards!
