N310 device?

 

Forgot to mention earlier: at device initialization you have to supply the 
external LO at 5 GHz,

as well as set the device argument as noted. Once the device is fully 
initialized then you can

change the center frequency & the supplied LO must be 2x that. Hope this helps!

I set the correct device arguments,but it doesn’t work correctly and also there 
is no error report.

I don’t what can I do next .

So I want to config this argument in mpm.conf file or usrp_hwd.conf file to try 
to use external LO .

I couldn’t find this file named "usrp-hwd.conf" in “/usr” .and also “mpm.conf”

 

Again, modifying the MPM config file is NOT necessary to get external LO to 
work.

What frequency are you trying to use?

Can you share the lines of code you use to set up the N310 for shared LO 
operation--including the initial device "make" with device arguments, etc.
