Hello,
I've some manuals from an OSA-5585, one of them for the EUDICS 3120. The
thing that Symmetricom calls EUDICS-3120 really is a FTS-5045 module
(Symmetricom in my case), that I think that it is the same that is
inside the FTS-4060. It seems that one common problem with these,
discuted some times in the list, is an STEL-1173 IC that has a failure
mode in which the outputs stop working (one after another, not all at
same time :) ).
Regards,
Javier

Hi,
I recently bought an Oscilloquartz 3210 cesium standard and although
it does
power up, it does not lock. All the parameters on the meter look
sensible, other
than the 2nd harmonic, #9 parameter, which shows zero. Quart
oscillator output
looks almost spot on in comparison with the lab Z3816. I have no info
on this
unit at all, so this may either be a dead tube, or other electronic
fault on
one of the many pcb's in the system. Ion pump had a small reading on
power up,
but now dropped back to zero.
I am looking for a user guide for this unit, or even better, a manual
with theory
of operation and setup info. Can anyone help with this, or perhaps
suggest a
source ?. Year of manufacture estimated 1984/85, from date code on ic's.
I notice that the tube is from FTS, the same construction as in the
FTS 4060, but
different part number and wonder if this was original fitment, or has
been
replaced at some stage...
Regards & Thanks
