Hi.

I got an octoclock-G (GPSDO included) yesterday.

I connected the octoclock (without external antenna) to usrp b210 properly.

However, when I executed the usrp_list_sensors.cpp or test_clock_synch.cpp which are included in examples,

sometimes I got that Reference is not locked, sometimes I got ref is locked.

Why is this so unstable? is this a normal behavior?

If I use GPS antenna, the reference lock status would be stable as "locked"?

Hojoon.

Could you share the exact arguments you used with these two applications?

What version of UHD are you using?
