Subject: Trying to debug GPS time issue 

I put back the Stanford Reserch signal generator. On a scope, the timing signal looks good. There is a small ripple and some noise in the flat parts. I found that when I unplug the DAC timing cable, the ripple and the noise goes away. 

I'm leaving the DAC timing unplugged for the night, and I'm using a script to track the difference between the machine time and the front-end time.

Unfortunately, this morning the model time is again wrong...

Update at 5pm, GPS times are still in sync.
