Simon,

 

You should be able to call:

 

get_clock_source() 
<https://files.ettus.com/manual/classuhd_1_1usrp_1_1multi__usrp.html#a1e7f679b2f273f7d38eeb1d92e801796>
 

 

and verify that the returned value is 'external'.

Hi,

 

If I set the clock source on the B200 to ‘external’ how can I verify that the 
B200 has indeed locked to the external reference? The lo_locked sensor always 
returns true, even when no external reference is connected.

[USRP-users] Clock Source

Hi,

 

If I set the clock source on the B200 to 'external' how can I verify that
the B200 has indeed locked to the external reference? The lo_locked sensor
always returns true, even when no external reference is connected.
