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?

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? $\endgroup$
