Re: [USRP-users] Error when trying to run USRP N310s using external LO

2019-10-25 Thread Mark Wagner via USRP-users
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.

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?
