I Checked the levels with the clock connected to the USRP ( and without)
The levels are fine ( about 600 mV rms on the scope)
additionally, I disconnected it from the load (USRP) to see if the
level changed. and they did (proving the cables are connected to a load).
the problem remains,
is there a command that could check if the USRP is locked to the
external clock?
what is the best way to debug this and to find the root cause?
Thanks for your help,
Guy
You can use "test_pps_input" which is one of the UHD examples.
Also, LED 'E' tells you whether the clock is locked to the external
reference.
