If I recall there are 2 MMIC chips, the large one you mention (U105) and
a smaller black plastic one (U100) to the left of the big one and to the

inductors marked L101 and L102 that supply the d.c. power to the chips.

I have two similar Symmetricom GPSDO boards
but with a slightly different parts layout
that were manufactured in about 2012. The

True - I believe all the Trimble Thunderbolts came from

Location Sensors. I know I removed over 200 T-bolts from
these units personally.
In the special it looks like they used two HP5071A standards, an
SRS620 counter, and a scope. They first made sure the stds were
in sync then took one to the building at the top of the ski lift
on New Hampshire's Mount Sunapee at 2726' elevation for 4 days
where it would be running a little faster

You are correct, I misspoke. While that point may have
been wrong I did check the elevation of Mount Sunapee
and it is indeed at 2726
Just a note to say that I bought one of these
prescaler boards for my CNT-81. One problem is
the way the board mounts in the CNT-81 the "in"
connector is toward the back instead of toward
the front like some of the other counters and I

of the 2003 Thunderbolt
I think I remember comments about it being used by the DAC. Wasn't there
some mention of the TBolt working with a dead -12 supply, but only as long as
the DAC output was above 0.
That was the conclusion. Actually the units these Thunderbolts were removed
from used -7VDC instead of -12VDC.
Hi:
What is the temp chip reading? Is it reading the oven temperature or just
the ambient temperature?
Ron
The DS1620 thermometer chip is in the corner of the pc board next to the
RS232 connector and diagonally opposite the OXCO so it reads ambient
temperature.

Not every GPSDO has a 10MHz OCXO.
That is certainly true although from a time-nuts point of view, 10Mhz is
certainly
a very nice number. I have linked to a photo of both sides of a Trimble 1.5x5
GPSDO built about 2008 that has a 1 square Trimble branded OXCO that has
a 76.80Mhz as well
I'd put the distribution amplifier between the TB and the divider

The units that these Thunderbolts were removed from solved
this problem by feeding the 10Mhz output through a power
splitter. One output from the power splitter went to a 2-way
distribution amplifier and the other went to
I have two Thunderbolts that I'm monitoring with
Lady Heather. The temperature on the older unit
(MFG 2/26/2004) seems to track the
environment. The newer one (MFG 11-24-2004)
shows 44.75 °C and only changes in increments of exactly 1°.

Do you know the part number of a chip to replace the DS1620?
The part number is the same, DS1620. What is important is the
revision of the DS1620. When Dallas Semiconductor/Maxim
'improved' the chip and went from REV-D (or D2) to REV-E they
made a change in the way the data was sent to the
I just got an DOXCO made by Frequency Electronics, Inc., so the first thing
I did was remove the screws from the outer cover to open it up and check
out the insides. Once I removed the foam so I could see the oven, I had the
feeling of deja vu. but I'd never owned one of these units before. I
Hi
I do not believe FE owns Morion. The most certainly own space in the Morion
factory. Last time I was there I saw the space.

'Own' may have been too strong a word but FEI is invested in Morion
and the FEI site doesn't describe Morion as a wholly-owned subsidiary
but one of its
