Wait, I think I get it: For bursty transmission, you're sug

Hi Stephan,
some prelims first: Can you manually sync the devices using
set_time_unknown_pps() before running the flow graph? I would like to
rule out VITA time issues.
Also, your way of setting the time should work; it's the same code as if
you were using tx_time tags. Although, that's something
Hello list,

In short: Samples input into the USRP sink do not appear at both hardware
outputs at the same time, but are set off by several sampling period
