Hi,I connected one usrp b210 and one usrp b200 to octoclock for
synchronization.I'm trying to verify that the usrps connected to octoclock is
"really" synchronized.To check it, I did as
follows.usrp->set_time_next_pps(uhd::time_spec_t(0.0));usrp2->set_time_next_pps(uhd::time_spec_t(0.0));boost::this_thread::sleep(boost::posix_time::seconds(2));uhd::time_spec_t
start_time = usrp->get_time_now() +
uhd::time_spec_t(0.1);usrp->set_command_time(start_time);uhd::time_spec_t
usrp_t = usrp->get_time_now();uhd::time_spec_t usrp2_t =
usrp2->get_time_now();usrp->clear_command_time();I think I did wrong, because
the results are different from my expectations.Q1. Can I execute
usrp->get_time_now(); and usrp2->get_time_now(); simultaneously? I'm trying to
use set_command_time, but it didn't work well as above.Q2. How can I verify
that the two usrps connected to the octoclock, is really synchronized? in terms
of time..I already used get_time_last_pps() command, this command works
perfect, the two usrps showed same value.but this command only showed "the
full_secs" which does not include frac_secs.. I want to check "the frac_secs"
between two usrps.I read this thread,
http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2015-January/012227.htmlBut,
I can't find the way to check frac_secs..Hojoon
