Certificated Time Nut (Clive Green) certainly a wavemeter should count, so should Lecher Lines, not sure about a calibrated candle or sun dial (maybe if its very nice) but not hour glass / egg timer. Really well aged tuning fork mmmm OK but not the bowl of water with a hole in it gismo. If GPS or Rb are to be the lowest these very important steps certainly drop off the bottom.

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 over a person's maser. Of course we could have levels as well. Master Nut (Own a maser or 5071) and then levels like primary, secondary and tertiary. The lowest could be having just a GPS source or rubidium. What do you think? Maybe we could come up with something interesting. Anyone want to make them up?

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 if you can?t get in to their sites. Another source for a manual on your instrument is www.yourmanualsource.com near Baltimore. They charge $25.00 per week but have been a good source for me in the past. When I rent from them I scan the whole manual. Good luck.

There should be a nice little phase bumps every hour.
