Hi Dick,
I guess I should have been more clear. By locking I meant using the
1pps output of the Trimble and a
separate house standard connected to a separate controller board such as
Brooks Sheras circuit.
The oscillator in the Trimble is ok, but it is not the same as a high
quality crystal
Yuri,
as a rule of thumb, read my message posted here last month:

I have 10 EFRATOM LPRO, and only one came with a faulty lamp.
I think it lost vacuum, and the glass looks clear but with
small white pigments. I inspected some of
Hi Antonio,
I have taken the cover off my LPRO but I could not see the lamp.
I guess it is in the smaller housing.
What does the lamp look like and how do you remove it?
I do not want to damage my unit.
cheers, Neville Michie

Secondly, the Jackson Labs advises that since the Fury uses the
external oscillator as its clock, that the oscillator should be
powered up before the Fury itself. I was hoping that I would be able
to use a single power switch to power both the oscillator and the Fury
simultaneously, but now
Hi Neville,
inspecting the lamp is a quite easy job.
Yes, it is in the smaller housing.
Unlock the check nut just enough, and unscrew the lamp (along
with the check nut) using a point shaped tool (a toothpick).
It is easy.
Don't touch it with fingers.
Before doing this, take note of how much

Actually, the best hardware for the job is the Soekris NET4501
which can timestamp a signal to a quarter microsecond.
That's why we use it for NTP servers in the first place.
All the software you need is in the FreeBSD kernel, and there
is a handy userland program
How much would be reasonable to pay for one of these on EBay? I see
someone asking $259 for one. I'm sure that TAPR's price was much
better, but I wasn't paying attention.

Hello Matt,
let me try to answer some of your questions about the Fury with an
Isotemp-134.
First I tried finding a datasheet for it, but Isotemp removed it from their
website. All I could find was that it has about 5ppb -30 to +60C stability. So
it's performance is between our JLT

Hi Bill,
thanks for sending the datasheets.
Looks like the unit has nominally +/-6Hz EFC range, slightly less than the
OCXO's we typically use.
I would thus try increasing the DAC Gain to about 30 to 40 and see how that
works.
bye,
Said
