You can do the ADEV just fine using Circular T. Long-term 5071 does not
dominate the TAI phase/frequency, but they do dominate for stability.
This is the difference between EAL and TAI, the 5071's go into EAL, but
EAL is then frequency corrected with a handful of primary references

Any chances that you will make it available also to others ?

At HP, it was explained that a primary standard
could be built on a desert island containing no
frequency standards nor any GPS receivers, etc.
and it would be guaranteed by design to meet its
spec. It could have adjustments, either operated
by a technician or a computer controlled algorithm,
In reference to:
"It would be cool to say one has a "primary standard", So, I think
we should be careful with the term, it's get thrown around too lightly."
Any of the hobby grade used Cesium standards is actually a Primary
frequency standard as it does meet the definition of:
A frequency
Some administrative info (no need to reply).
1) We are still working on the time-nuts upgrade. When things solidify
John will post details.
2) The time-nuts mailing list is currently unmoderated.
a) When moderated, every posting is checked manually before it goes out.
This is possible
These are the files I downloaded several years ago, what looks to be the
windows executable is inside a secondary zip file, publish.zip.
I don't recall trying to use any of this as I always calibrated 5680As using
the manual method.
I've now uploaded the file to mediafire...
To all who requested,
I uploaded the entire .Zip file to KO4BB manual site: http://www.ko4bb.com/
The filename is Fe5680Calibrator.zip
It should be available to download soon.
Cheers,

Maybe HP5071s will get their ADEV when optical clocks will officially rule...
