I'm thinking that timed tune commands will not work on tagged streams in burst mode. Is that correct? I've been looking at the USRP sink block code and it supports the timed commands on the stream, but from reading a recent thread, it seems like this will not work because of how the DUC derives it's time:
https://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2020-March/061611.html This thread says DUC derives it's sense of time from the samples, and if the samples are not streaming, the DUC will not keep track of time. Therefore, the timed command will not be executed. For example, I set the tx_time tag to 1.0 second and the burst is 0.05 sec long. Then I place the tuning command tag on the last sample of the burst with a tune time of 1.05. The radio does not actually tune until I transmit the next burst at 1.1 sec (0.05 sec dead time) and then it tunes at approximately 0.007 sec into the middle of that burst. I can try to implement tuning during the dead time by making calls directly to the C++ api at the appropriate time in a separate thread, but before I do that I just want to confirm that this burst time-tag method will not work. Thanks in advance, Jeff
