Hello everyone!
My name is Isaac. I have a curious situation here... I've
generated a pulsed signal per second. I've saved one second
period in a .h5 file, so that I'm sure I'm having a fixed
signal per second, and then repeat it in my GRC flowgraph. .
To use this signal as Tx I'm trying to synchronize a USRP
N200 and a trimble in GRC. After run my flowgraph, this is
what I see:
The yellow signals are the PPS of my trimble and my purple
signals are my tx signal per second. They are periodic in time
but when you see it deeper, the difference between the timble
PPS and my Tx signal is approx 97 ms. I think this difference
should be close to cero, as my USRP and trimble are
synchronized. ¿What is happening here? ¿Is this a normal
behavior? I'm using unknown PPS to configure my UHD:USRP sink
in GRC....
I'll appreciate any help to clarify this behavior
Regards
Isaac T.
