For my application I need a accurate timing. To this end, I connected an external gps clock (Leo Bodnar Mini Precision GPS Reference Clock) to my PlutoSDR.
Is it possible to recover the pps afterwards? Or is there a way to time-tag samples (absolute or relative) and propagate this through the iio framework?
Accuracy is the most important part.
If there are any other suggestions on how to achieve accurate timing, please let me know.
