Jerry,
Please contact me off-list. I have questions, and might be very
interested in your T'bolt.

Pardon the interruption. If any of our 1800 members uses a Samsung / Galaxy Tab

I have only worked with the GPS part of the KS system but some time nuts may be
able to explore the use of the second half and they are available at

I understand what you're trying to do. Your idea would work
Hi
The Trimble Thunderbolt does not have a 1 pps between the GPS chips and the
OCXO. It makes the
link between the two portions of the system in a different way than the typical
GPSDO. It uses the
OCXO as the clock reference for the GPS chip set. It then uses phase data on
the received

One of mine is off in similar sense. It can't be

I have received information off the listthat I think will be helpful.
I will give it another try.

Thank you all for your answers,
I do have an additional question. Did anybody install an external 1PPS/10MHz
input to the Trimble Thunderbolt board ??
With the idea that, when the adjustment loop is deactivated, an external signal
can be supplied to the Thunderbolt, and the Time Interval
This is fascinating. I am a bit skeptical if this actually happened.
I had an opportunity to meet an engineer that was involved with early
HDTV development. Apparently early in his career he invented a color
projection CRT for cinema. It had some sort of target inside of it (I
think plastic)

It might care that it is surrounded by some gas. If the container is mostly
empty, the He could be the only gas, so the pressure could go from x to 10x.
It does sound unlikely to me, but not

If you can obtain a similar scope, you could use two identical 1 Meg probes
Helium is lower density, a feature used to reduce turbulence in patients
with airway stenosis. Perhaps the lower density changes the resonant
frequency of the MEMS oscillators. (Though the penetration and
concentration are rather suspect in this description.)

Hi
More than sketchy, it sounds a bit crazy.
MEMS are not a lot different than any IC in that you can get packaging issues.
Put them
in a high pressure “bomb” test and you will see the same issues that you do on
any IC.
The gotcha is that an IC is die coated and a MEMS oscillator likely is
