Hi Everybody,
Many thanks for all info regarding this module...It is running with TAC32
software but unable to switch over to self survey mode... the battery is low,
only +1,4Voltage.
Best regards,
Ernie.

none of these nist references will download to me in Australia,
is it some sort of national security issue?

They download fine across the ditch.
Probably a problem with your ISP.

The problem with the working configuration was that the DSP code
consumed virtually all the old SuperSPARC-II CPU's capacity. In
Intel x86 terms, these were roughly equivalent to a pre-MMX Pentium

If I randomly pick up a FE 5680A data sheet, I find that it's short term
stability is 1.4/sqrt(Tau) x 10-11. Since I never doubt anything I see on a
data sheet, this immediately tells me I should get 1.4x10-12 at 100 seconds,
and I only have to wait for 10,000 seconds to get to 1.4x10-13.

The cheap Datum LPRO-101s coming out of China appear to be capable of great

(This plot shouldn't be taken seriously beyond t=1000s, and the flattening
effect at t=700s might be the Thunderbolt's fault. I haven't run my
Hi
I agree that if you simply bolt the rubidium to an old engine block and toss a
blanket over it, you might get some pretty good thermal stability in the hour
to couple hours time period. That's certainly a better approach than putting
some kind of DC heater (and it's varying magnetic field)
Bob
Some isothermal radiation (thermal) shields between the blanket and the
top of the Rubidium source may also be required.
Unless you have a hydrogen maser you will need to use 3 rubidium sources
each with its own engine block in order to determine AVAR (using the 3
cornered hat
