Marcus, Thanks for your response; I believe I am. The math is spread over two lines: uhd::time_spec_t expectedTime = startTime + (double) ( num_tx_samps ) / (double)usrp->get_tx_rate(); Best, Doug On Tue, Mar 9, 2021 at 10:20 PM Marcus D Leech wrote: > Shouldn’t

Hello -- I've got some questions re: latency with the x300 over the 10GigE interface. If I use the latency_test example operating at a rate of 50 MSPS, I have no issues with a latency of 1ms. The latency test receives data, examines the time stamp, and transmits a single packet. I have an
