[time-nuts] About HP10544A

I looked at your oscilloscope signal and it looks cleaner than mine but I
looked at mine at a slower sweep and both 50-ohm termination and 1-Megohm

Can you look at it on the oscilloscope with 50-ohm and 1-Megohm termination
and display several cycles?

I suspect we are seeing the same thing.  I just don't know if it is the
normal function of the 10544A.

Yes there's many network bans and all thanks for this belongs to couple
of spambots trying to scan the webserver at multiple IP's at same time.

I just changed the IP bans based on IP address where you send your mail.
You should now have access.

Can you see the pictures?

You are not doing anything wrong but someone else does with their
spambots... :-(

Oh no.. then it could mean that 544 is no good for that project...
