Hi I own a B210 and I have a GPSDO that's installed but I do not have the antenna yet. Can I use it as a 10MHz reference and PPS until I obtain the antenna?

$\begingroup$ Are you talking about a USRP B210? $\endgroup$– David Hoelzer ♦Commented Oct 27, 2021 at 19:42

$\begingroup$ @ShaneT that comment asking for clarification was a gentle hint to edit the question so it is complete. Assume comments disappear the moment someone reads them; they are not considered part of the Q&A, and are not persistent at all. $\endgroup$– user21417Commented Feb 25, 2022 at 16:44

Yes, you can.
But you don't win as much: the more modern B210 GPSDOs aren't worlds better than the standard integrated TCXO of the B210 is, anyway. So, I'd recommend using clock source = internal until you get an active antenna for your GPSDO.
Generally, if you know you can work with the lower frequency accuracy or timing, why even bother with a GPSDO? All real-world receivers need to do frequency recovery, anyway, even if they had GPSDOs – unless nothing in the environment moves.

$\begingroup$ But what commands do I use to do this? (Use my GSPDO 10mhz reference and 1PPS) Is this done by UHD automatically? Or must I implement this via some command? What command do I issue to see if the B210 is using the GPSDO as I want? $\endgroup$– ShaneTCommented Oct 28, 2021 at 0:24
