Well, if you figure out how to introduce a 100 mS delay with a
short length of cable, you should see a patent attorney.
Wait a minute. Aren't you using a homebrew divider to get 1 PPS
from the 5061? That's a fine way to get long lasting offsets, but
I can't imagine why it curved up or why the offset went away. My
money's on the cordless phone or static electricity.

Thanks for all the comments. It must be a slow afternoon/evening!!!
You've given me several things to check out. In addition, as I was
looking at the hardware in the basement I now have a suspicion that it
might be a cable problem, specifically in the cable that goes from the
5061A PPS output to the TIC input; that cable might have moved when Jody
opened the control panel door on the standard and if it was marginally
faulty, it could create a transient. A transient lasting several hours
is a bit odd, but who knows...
I want to keep things in stable state for another day or two to get my
offset value at this C-field setting, and then I'm going to test both
the cable, and the other hypotheses you all have suggested.
Thanks,
John
