Hi, I have a setup of several X310s connected over 10Gbit Ethernet, and synced with an Octoclock. I'm generating signals on a PC, and streaming the signals to the X310s to get coherent waveforms. For now I'm generating sinusoids where the phase of each channel slowly varies with time at different rates. I use UHD 4 on Fedora 32.
In case the CPU load spikes and an underrun occurs, the phase relationship between the channels out of the X310 changes / is lost. (Presumably because the X310 knows which packets belong to which channel, but not which packets should be aligned in time?) Is there a way to avoid losing the established phase relationship, despite the underruns? All examples I've seen of multi-USRP TX only sets the timestamp for the first send() call, and clears it afterward, so I'm not sure if timestamping is the correct way to do it.
