Re: [USRP-users] Error when trying to run USRP N310s using external LO
Unfortunately not, I'm trying to get the N310s to operate at 584.2 MHz, so my LO is going at 1168.4 MHz (there's a note saying the external LO should supply twice the desired center frequency). I would have thought there's no need to specify the center frequency when running with the LO switched to external, but when I run the setup without specifying the center frequency it doesn't seem to work. -Mark On Fri, Oct 25, 2019 at 6:27 AM Rob Kossler wrote: > The N310 data sheet (in one of the footnotes) indicates that external LO > is limited to the frequency range 300-4000 MHz.

Re: [USRP-users] Error when trying to run USRP N310s using external LO
The N310 data sheet (in one of the footnotes) indicates that external LO is limited to the frequency range 300-4000 MHz. Are you trying to operate below 300MHz?

[USRP-users] Error when trying to run USRP N310s using external LO
Hi all, I'm currently trying to run a set of USRP N310s all using the same external LO, but I seem to be getting this error "[ERROR] [0/Radio_1] RX LO lowband does not support setting source to external" which will repeat for all the radios. I tried looking online for the source of the error but no dice. It seems like the radios are ignoring the LO I'm giving them and using their internal ones instead. Any thoughts? -Mark -- Mark Wagner University of California San Diego Electrical and Computer Engineering ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
