hi guys,
Im using a USRP-N and a USRP2 to send a Square Signal to another USRP2 for
proving Synchronization by using PPS.
after execute a get following message:
linux; GNU C++ version 4.6.3; Boost_104800; UHD_003.007.000-1-stable
Using Volk machine: sse4_1_32

It seems to work well,but when i look into the scope sink i found a pretty
randomed delay between 2 Transmitters.
it looks like this: --˜˜˜--___--˜˜˜--___--˜˜˜--___--˜˜˜--___
after restart it would look like this:-˜˜˜˜-____-˜˜˜˜-____-˜˜˜˜-____-˜˜˜˜-____
I tried set a delay-block to compensate,but i realize coz of random i cant find
a constant delay.
did I do something wrong or there is a certain way to "tell" the 2 Transmitters
send Signal in the same time?
