I wish Symmetricom would release source to the old TrueTime / Datum products... 
But I'm sure most of that source code has been lost 
/ thrown away. 

For instance, the older network time servers are much cooler to me than the new 
models. The old stuff was custom designed and 
specifically written / tweaked by hand. The newer time servers are just 
off-the-shelf single board computers, a GPS module, and then 
*maybe* a custom oscillator module Then they just run on a *nix OS with 
some small custom scripts to do the timing and automate 
setup... Just not the same...

Isn't that a relative question?  "a lot of spare time on your hands"?  I 
have very little and each uS extra I have is a blessing.  Time?  Really? 
Maybe I'll just have the year I die engraved.  After all, even the "year" is 
subjective (which calendar are you using as a reference?)...  Maybe it'll 
read, "*my stated birthdate*"... and "left this world before you did." to 
those reading it.  I don't see this as an infection as much as I do an 
incurable disease.


When I'm dead...  who cares when it happened.  It just happens... to us all.

Wake up each day (if you do) as THIS day may be your last... and live, 
learn, teach, love, and care for those who need it... especially your 
family!  Now, why hasn't my latest OCXO arrived yet?

To sort of make an on/off topic comment, here in NY, we have recently
begun using hypothermic protocol on cardiac arrest patients that have
undergone a reversal. If the heart has stopped and been restarted
either with a defib or by CPR alone and we are on scene in a short
enough span of time, we can start the treatment using chilled saline
IV to lower the patient's body temperature rather dramatically en
route to the hospital. I got to work the first one of these in our
area a few months ago. Absolutely fascinating.

Of course we need to make very careful and accurate note of the time
the treatments begin. :)

If you want a sub-microsecond time of death, sit on a bomb like Major T. J. "King" Kong

That should be good to a few 10's of nanoseconds.


The GPS satellites NUDET payload does this and then transmit their 
measurements on the L3 band. They pin down the place of blast to within 
a few 100 m so it gives a fairly good precision in time-measurement.


The L3 band is at 135*10,23 MHz by the way. Radio-astronomers have 
learned to hate it, despite the filtering being done to keep the radio 
astronomers happy. There is some interesting papers to be found relating

Mike is correct.  Brain activity does not screech to a halt but peters out
over a period of minutes once the heart stops beating.

When we (I'm in the medical field and not, by any stretch of the imagination
an engineer) speak of someone being "brain dead" or "flat line EEG," we
don't really mean that there is no electrical activity in the brain at all,
only that there is no purposeful activity.

That is why, in most jurisdictions--not all--death is defined as cessation
of heartbeat.  In the eyes of the law, that's a dichotomous variable; it is
or it ain't.  Which means, from a legal perspective, at least, that when lay
people say that so-and-so was dead for a time and then brought back, they
are correct, cornball as it sounds.

Actually, heart beat doesn't cease like snapping a light switch but trails
off into meaningless blips and wiggles that can go on for a while.

Clinical death, to physicians and other health professionals is when the
machine has quit and it can't be fired up again.  Vague, yes, but perfectly
adequate.


For several reasons this definition is not usable for all cases anymore. 
There are cases when the brain can be considered dead, but the rest of 
the patient is relatively healthy. For the purpose of making organ 
transplantation possible, brain death is clinically being used, with the 
good old ticker and breath as a rough indication and subsequent failures 
of restoring those has failed.


There is one case in which a Swedish medical student was out skiing in 
Norway and went through the ice and was being held there by the strong 
water. It took them 45 min just to get her out of the water. Her heart 
had stopped. Her respiration had stopped. She have had no pulse or 
breath for over an hour when they finally started working on her at the 
hospital. She survived and is almost completely restored. She works at 
that very hospital. Cooling patients down causes less brain-damage and 
is now an established treatment for certain trauma cases. The 
heart-compressions being done helps a lot to keep brain-damages down. We 
keep learning more and more about reducing damages on heart attack patients.


So that definition has become less and less meaningful for that very 
reason. Not all legal systems reflect this thought, but as I recall the 
Swedish legal system did change this a few years back.



So.I see no way in which one could determine with precision when life
ends.  At least not with the precision that this group would consider even
minimally acceptable.


Agreed. We might agree on day. Maybe hour. Then it becomes kind of 
difficult.

Thanks for the info. It is obviously Rohde&Schwarz. Funny!  All  other 
units I have seen or owned did have a beam current reading, have not been  able 
to find it on these units. Besides Voltages it has oven,  contr.  Voltage, 
integrator, AMPL. and 2nd Harmonic. I still have two cesiums and  several 
rb.s and have worked on quite a few, so I am very familiar with the  subject, 
the problem is that I am trying to help a friend over the phone and  find out 
what he has and how good the units are before he puts them up for sale.  
One has the green light on but I would like to know what the beam current is,  
also which OCXO. The OCXO will make the biggest difference.

Any phase-locked loop  contains an integrator that has the phase

The integrator output settles at some  voltage that causes the phase
error to go to zero (until something  changes). This voltage has a
range, like +/- 10 volts, where it is able to  vary the VCO. When
the voltage reaches either limit, the integrator is said  to be
saturated. I'd expect the Integrator meter to show the output  of
the integrator. Normally, you'd trim the VCO to center the meter  at
zero.

If the meter saturates in either direction, the PLL is  open, which
means that the integrator output isn't getting to the VCO, or  the
VCO isn't varying, or the phase detector isn't detecting, or  the
integrator is bad, or anything else that would break the  loop.

The Amplifier probably isn't the one after the integrator, but  is
the one that amplifies the output of the physics package. In a  Rb
standard, the physics package is the phase detector for the  PLL.

Does any  one have any info on the RS cesium standard. Specifically does
anyone know  what switch position 7 Integrator and position 8 Amplifier 
measure?   Any help will be appreciated. Thank  you.

Try running auto cal after loading factory defaults into ram.  That may
clear up your problem.

Looks like a normal 32 x 8 static ram. But before you go ripping it out.
Cut and lift the power pin and measure the current draw. You can always
resolder a wire to the lifted pin. Should be 1 ua or less in power down.

Or roll your own.
If one eschews MMICS and opamps and uses inexpensive BJTs achieving a 
phase noise comparable to or lower than that of the above isnt too 
difficult.

Subject: [time-nuts] Distribution Amp suggestions

Hi,
We have more expensive distribution amps around the production facility
here at RAKON than I'd care to count, and always seem to need more. I am
looking for additional units as the requirements expand, something like
the Symmetricom 4036B which we already use. Our need is for 10MHz
distribution.

Since we need to purchase several of these, can anyone suggest a unit
with similar performance and quality that would be lower cost than the
Symmetricom 4036B?
