Hi,

Last time, I success locked the 1pps reference input signal.

 

But when I try to capture the tuning word parameter by the tuning word logger, the log file just shows the tuning word was changed every time, and the frequency range is quite large, from 100MHz to 900MHz.

 

  If I just manually update it at the Status window, the tuning word history is quite stable.

 

  I also monitor the output signal, it also stable.

 

  What happen to the tuning word logger?

 

  I also update two log file for your reference, one is capture the tuning word every 10mSec, another one is 1 Sec.
