Ok, I did the reset, and it's much happier now.
I'll keep an eye on it.

Hi
If one shows 38,000 ns error, it’s no longer locked. It may *think* it’s doing ok, but it most certainly is unlocked. What is the DAC voltage doing? ( in some cases the DAC takes a long time to get to a limit and trigger an error flag).
