Hi, Marcus.1. usrp_list_sensorsI didn't give any aruguments, I just typed "sudo

thing is that when I executed the test_clock_synch "without reference clock/PPS
connection"(i.e. the usrp does not get reference clock and PPS from
octoclock),It also showed that Octoclock time == usrp time, this does not make
sense. For example,Running 10 comparisons at random intervals.Comparison #1 *

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?
