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
You will also have latency introduced by the ADCs themselves, as well as
baseband analog filters if applicable. If you need very accurate
calibration of arrival time, it is best to generate an accurately timed
calibration signal using a GPS reference. You could continue to use your
TX/RX loopback t
Hi Nick,
Thanks for the info. Sure, I would have to take the analog parts into
account too. I was hoping to know the latency at microseconds level at
least. I do not have an oscilloscope. Wouldn't it be possible to know the
minimum latency introduced by the digital filters at least?
