When switching you find one guy walking on and off the field. However,

Yes for 12-hour display but here in Europe we usually have 24-hour
displays. Of course analog clocks are always 12-hour.

Quartz movements and dials having hour hands that rotate once in 24 hours can

I just bought a couple of 5680A's that have the same FEI p/n. They are
pop-riveted to a heavy double-sided board., obviously cut off from a
longer board. I've removed one of these from it's board/heatsink. There
are two pots on the board, only one of them can be trimmed with the case
on. The sinewa
I have done some more checking and identified the C field pins: one has

units with C coil adjustment. Xtal Osc. is 60 MHz on this unit. Also has an
AD 9832 in it, unit is specked at 25 MHz so it does not run off the

Does any one have info that would help to do so.
I don't know if this applies to your Rb but this is pretty typical of the

In the LPRO the C field is created from a low resistance coil that is
I am not familiar with how these units are set up. I have a couple of
older Ball units which simply put out 10 MHz, but these FE ones seem to
have this external crystal oscillator? How does that work? I've seen

Hi Peter: The external oscillator is just "thrown in" to the deal; they
have nothing to do with the Rb unit. You also get a gratuitous 9 pin
connector. These units should be self-contained.

Bert,
Your comment about the AD9832 being a 25MHz part made me think, and I too
wonder how it might all work. The data sheet calls it a 25MHz part, and I agree
with you that it might be expected that some extra division occurred between
the ~60MHz Rb loop and the synthesizer MCLK.
That's not th
I did measure the Xtal and it is 60 MHz. That is the only thing I know for
sure. I did not probe the output of the DDS because with my 69 years old
hands I do not want to slip and destroy the unit, some one else may want to
test it. As a group we should be able to solve the problem since the

I think those pop-rivets are actually screws with a small hex socket in
the center. That's what was
Aha. Well, they were hollow, so I drilled 'em out. Didn't want the big

Fellow Timenuts,
Here are the clues that will answer some of your questions concerning
the newer
version FEI Rubidiums and also its Kissing cousins from Symmetricom;
the newer
series XPRO and SA22c. It appears both companies have came with up with
same idea

Hi Folks,
I played with a few of these that came off the cut up board you describe.
The ones I had put out 1PPS ONLY!
Internally they ran at 8.xx Mhz that divided down to the 1 Hz.
I was able to engineer a tiny add-on board using very small 10Mhz
crystals and made them put out 10Mhz.
By the way
Kind of joining in late.
Might this be the epay womart for $49 inclouding shipping?
That really is quite a good price.
May also order one up.
Regards
Paul.

That's it, I think. Look for the large base and the extra crystal,
completely extraneous.
