Hello, In the paper below, the authors say that they have set up their USRP device to include timestamps for each recorded sample, but do not provide detail on how this was achieved:
https://ieeexplore.ieee.org/document/6533293 I have been looking into what is required to achieve something similar. Particularly, I have been working with the source code of the rx_timed_samples.cpp example provided in the UHD files, along with this page in the Ettus manual: https://files.ettus.com/manual/page_sync.html Looking through the rx_timed_samples code, it appears that the metadata associated with the recv(..) function contains a time_spec field which is the timestamp for the first sample in the IO stream, but it's not immediately clear to me how that might be used to timestamp all of the samples, which makes me think this may be the wrong approach. Is there a simpler method to do this that is known? Tangentially, I've also looked into adding the timestamps through GNURadio, but there does not appear to be a way to do this as far as I can tell. Any help is much appreciated. Thank you, Alex
