Elio,
I've contacted with the guy who dissected his FE-5680A in YouTube. I
offered to pay the shipping and he agrees to send the board to you, so
he needs your address. Please contact directly with me.
Regards,
Ignacio, RB4APL

should you center the VCXO as a matter of routine maintenance?

I think a very asymmetric sweep makes the most sense.
First some history of sailing ships.
Hi
They do indeed need to know that they start low and go high. They do need to
sweep to either side of the resonance. Every Rb I've ever torn into does
those things.
Why sweep *way* low, and almost not sweep high enough? Normally the sweep is
centered.
Why spend most of the sweep time not
Hi
Some of the schematic is less important for how it works but all of it is
useful for troubleshooting. I wonder if splitting off stuff like tracing out
the power supplies and heaters might be a good idea...
Once we get into things like typical voltage levels, we will need to look at

I can see the programmer writing code and he knows he has to wait for
warm up. So he does a sweep then calls wait().Or it could be the

They didn't look all that odd to me. As long as you do the sweeps every
now and then you will lock up. I think you need to tell me what's so odd
about them.

Hi
If you look at an LPRO or FRS or any of the other brands of Rb's their sweep
is very different. They don't spend very much time at the ends of the sweep
at all. It's pretty much a triangle wave sweep up and back sort of thing.
They don't seem to care weather they catch the lock going high to

Just curious,
Has anyone on this list actually contacted FEI and enquired about a
schematic or other info about our 5680 units? They are still being sold by
them.

In additional to the standard ADEV answers,
Two important additional performance numbers to consider when testing
and evaluating a RB Osc, are its TempCo, (as in freq change per degC)
and its Ageing rate, (as in drift rate per day).
Anyone with a spare TBolt can measure them.
One simple method
It's possible to use Bresenham with two integers 10,000,000 and
32,768 but I found no way to perform all the 24-bit calculations
on an 8-bit PIC quick enough. Removing the GCD often helps
but in this case the accumulator remains 3-bytes wide.
Huh? Dividing 10,000,000 by 4 (to match the PIC

Lady Heather's osc drift rate calculation does assume that the temperature has
been stabilized. John DuBois and I did quite a bit of work to find a way to
unwind the osc parameters from the available unstabilized reported data using
SciLab on the log files, but nothing seemed to work
The other way to get around the inaction of the temperature effects and
drift effects to start and stop the displayed plot at the same temperature
and more important is do the ageing ageing rate over a an multiple of
complete temp cycles which is why that plot is exactly 7 days long. giving 7
