I recently got a strange little 1U FEI rack mounted unit called an FE-7923F-100-1,
which appears to have rear 10MHz and dual 100Mhz outputs. it is called a
Frequency Reference Unit.

sadly, my unit has a fault light, and no outputs. All the internal supplies look
good, and there is an FE-83AA (10.0Mhz) and FE-1020-100 (100Mhz) OCXO inside.
both of these work (when measured at the oscillators), and seem to have
meaningful control including EFC, and I tracked down the adjustments in a sea of
what seem to be prototype boards next to the oscillators. so, I have two good
sources, adjustable, but still no outputs.
the OCXO signals disappear into a set of boards with no useful markings as to
function, and look mainly digital.

the 100Mhz unit has only about 200mV p-p output, which seems low to me, the
other has lots of signal. I cannot find any data on either unit on line or at
the FEI website, so any data that is out there would be very welcome, so I can
be sure they at least are running correctly.

I am hoping to use this rack as a source of RF reference signals in other gear,
but clearly I will have to either gut the rest of the circuitry and add some new
buffers, or figure out the rats nest of hand wiring to determine why it's not
working. any help in that area hugely appreciated, and I can send pics to
anybody interested to know more about the internals.

the rear apron has AC power in, a 10MHz output SMA, a switch next to it that
says INT/EXT REF. (set to INT), but no way to attach an external ref. then
there's a D-Sub filtered connector, that runs to the stacked digital boards, but
its purpose is unknown as I cannot see where the connections go. there are also
two 100Mhz SMA outputs, but all outputs are dead, with no signal, and the front
ONLINE green LED is dark, and the red FAULT LED is lit. the oscillators do not
run to the rear jacks but disappear into three pcbs.

hoping for some FEI data if anybody has some to share.
all the best,
walter

Walter pure speculation.
Maybe the 100 MHz is superposed to be locked to the 10 MHz.
With a scope see what the drift rates are between the two.
Adjust EFC slowly to get the 100 MHz to go below the 10 MHZ if its running
fast.
See if the light changes to green.
If it does you know that the system is supposed to be locked and they
aren't.
Most semi good systems systems do not allow outputs if there is a fault.
But you know that already.
Pure guess.

Paul

Dear Enrico:

Let me be the first to congratulate you on winning the 2018 Cady Award “For ground-breaking contributions to noise analysis and signal-source theory, and experimental achievements in the electronic and photonic domains.” I hope you will be able to join us at the 2018 IEEE Frequency Control Symposium, which will be held at Squaw Creek Resort, Lake Tahoe, California on May 21-24, where we can properly recognize your achievements with the formal presentation of the award. Again, congratulations on receiving this well-deserved distinction.

Best regards,

I received mine yesterday, fired it up today and the Red Fault light lit up. I expected that.

I checked the Power, +5 and +15 looked OK.

Nothing out of either 100 MHz spigots. I hooked up the 10 MHz Input to my GPSDO and

still nothing out either 100 MHz spigot. Also checked with the Int/Ext switch in both

positions.

At this point, I have done all I can do. Until someone smarter than me finds something, up

on the shelf it goes.

BTW, they did put a lot of screws on the cover !!

Thanks, Dick, W1KSZ
