Hello, I am using two x310s both hosted from a common PC. I've stitched together a few UHD examples to transmit a pre-recorded waveform from one x310 and receive at the other at the exact same time. I'm using an FMCW waveform and would like to run a correlation on the received signal to make an attempt at measuring distance between the Tx and Rx. I used a common reference and PPS between the two x310s and scheduled a transmit and receive by passing a time_spec in the tx_metadata variable for the tx_stream->send() function as well as the time_spec variable of the rx_stream->issue_stream_cmd function.
My question is: how much stock do I put in these time_spec values? Is there some timestamp I can retrieve that will tell me something closer to the truth about when the first sample was emitted from the transmitter or was recorded at the receiver? Or can I rely on the SDR adhering pretty strictly to the time_spec value it was passed provided it was set sufficiently far in future to give SDR time to schedule commands? Thanks!
