Depends on whether you're traceable to NIST...

Hi John,
Ok. Great idea. We should make up a certificate that looks
like an NIST cert. that certifies that if we have a working
Cesium or hydrogen maser standard or two or more standards that can
be traceable to NIST, you can become a Certified Time Nut. It will
look nice hanging
Scan one at RBG 600 DPI or better; I wee what I can do.

You really need to get Borgmans permission to include the
Zits nanosecond strip on the certificate.

Well I have been to NIST in Boulder so maybe I am certifiable
Doug you might check
http://cp.literature.agilent.com/litweb/pdf/08642-90224.pdf for a copy of the
operating and calibration manual for the 8642A. There are probably some other
sources of free manuals on the internet. I have had problems with the various
Agilent servers of late, so be patient
whats this lesser standard in the gps and rubidium stuff. i have a hp 117a
tracking receiver that prints days with straight lines from my rubidium osc.
also three hp 59309a clocks that say i have the correct time for weeks
running from the standard. hope that makes me at least in the middle
If your 117A, listening to WWVB, draws straight lines
then something is wrong with it. You should see a change
between day and night.
Ah, unless you live near Fort Collins, CO.

A flat line isn't always good news. There should
be a nice little phase bumps every hour. Do your

Sorry for the advertisement, but I thought this would be of particular
interest to the folks on these lists.
Some time ago I mentioned that I was working on a clock synthesizer
board that could be used (among other things) to get much better
timekeeping for applications like NTP.
The idea is to

Ah, yes, I have one of those FAA tuning fork standards . Never
occurred to me to mount it in a three dimensional gimbal in order
to discipline it to GPS. Might wear out the mechanism, though,
as it attempts to track the ever-shifting GPS reception.

Gee, maybe some of you need to get a Bulova Accutron. I think that is one of
