Sometime (I didn't have it connected) in  the last couple of weeks  my Z3801A went into gps week rollover.  It now reports the year as 1997.  It had been working propely.   Lady Heather caught the anomaly and automatically added 1024 weeks worth of seconds to the date/time which compensated for the error.   I always wondered if that code would work...    

If you have a Z3801A that had been working properly you might want to check yours.  Different firmware versions roll over at different times.

BTW,  Thunderbolts will roll over during the middle of next year...
