[time-nuts] Thunderbolt Anomalous Behavior

[Peter Putnam]

Greetings,

I have posted two plots graciously provided for me by Lady Heather, 
showing strange behavior in my recently acquired Thunderbolt. It has 
been powered continuously for the last two weeks.

The plots can be seen at:   http://www.ni6e.com/TBolt/

An explanation for the abrupt change in DAC voltage and PPS offset would 
be appreciated.

Thanks,
Peter
