You are correct, my statement was imprecise - I generate numbers
Bert,
That looks like a useful board. Certainly some of the oscillators
I'm giving away would fit nicely on it. Since it looks like a two
layer board, a quick check at pcbway.com puts the cost at $.79
apiece at the 100 quantity exclusive of shipping.
Best,

For this you should expect 1.73 which is sqrt(3). For example:
C:\tvb> rand1 100 | adev4 /a 1
rand1 100(count) 1(sdev) 0(mean) 1540577979(seed)
** tau from 1 to 1 step 1
1 a 1.732671e+000 98

A search for the Navy designation O-1695A/U for the HP5062C cesium
clock leads to an interesting webpage for the history of Navy time
dissemination, http://www.navy-radio.com/freq-equip.htm . It claims
that the service manual for it is 0969-LP-171-6020 . That manual
could not be found on line.
I do not think you understand under no circumstances will I get in to the board
business.I do all the boards for an off list group 20 designs last week from
China.Willing to help some one to do this board it was part of last weeks
shipping Corby was first to test it so I am willing to share it
Al OCXO's have Ref outputs will look at adding EFC SMA. Send me the footprint
of the 8663 and I will take a lookBert

I'm not up to doing the whole project, but I would certain be interested in 2 or
3 boards for sure.

ref voltage output.

Although it is not the cheapest, OSHPark will let you upload your board as
gerbers and share it with
Hi
Well if this turns into a major enterprise …. do a second board with a
different set of
footprints. Probably better to see if this one will fly first …..

Hi
I think what is needed is somebody to stand up and say “ok, I’ll handle all the
ordering and shipping stuff”. No, that somebody is not me …. sorry about that.
There are a *lot* more board designs than just this one floating around. This
could
turn into a fairly complex little enterprise.

Hi, all
I'm simulating some noise to try to improve my somewhat sketchy
understanding of what goes on with the various noise types as shown on an
ADEV plot. Nothing fancy, ~3600 points of gaussian random numbers between 0
and 1 in excel, imported into Timelab as phase data, scaled to ns.
