As one of the Beta-testers I can highly recommend this, it really gives
your HP5370 a kick into the next millenium.

The potential for future improvements is also virtually unlimited:

How about hooking up an LCD display and calculate and show allan
variance in real time ?

Thanks a LOT John!

Re: [time-nuts] Another atomic clock question

2014-02-24 Thread Bob Camp

Hi

Ok, so 0.1 second at the sync point is indeed a reasonable estimate. If that’s 
all you need to deal with (you correct out the crystal offset one way or the 
other) then:

At 1 day you have 11.5 ppm accuracy. Roughly a 100 Hz beat note with WWV at 10 
MHz.

At 10 days you have 1.15 ppm. Roughly a 1 Hz beat note at 10 MHz. 

At 100 days you have 0.115 ppm. That would be about a 10 second period beat 
note.

None of that is to say that a beat note is all there is to getting accuracy off 
of WWV or that the two approaches deliver the same net accuracy. Yes I’ve done 
the 10 second beat thing, it can be done with care and a good stable WWV 
signal.

 I suggest using a direct electric (1.5 VDC high-Z) or indirect magnetic (high

 with your local frequency standard and over several days you should get 
 accuracy better than 10 ms per day (1e-7). Here's an example of a raw phase

Re: [time-nuts] 5370 processor boards available

2014-02-24 Thread Chuck Harris


As an early adopter/beta tester, I highly recommend this board!

As yet, the board is only giving a glimpse of its potential, and
yet it is completely replacing the original 6800 processor board.

I am using a 5370A, with emulated 5370B firmware, and my A appears
to now function as B in all important respects.  It runs quite a
bit faster than it originally did... and the Beagle Bone Black that
has taken over the 6800's duties, isn't even breaking a sweat.

At this point in time, the BBB single board computer is doing a
software emulation of the original 6800 microprocessor, and is
running a copy of the original firmware of either a 5370A, or B,
model counter.  The BBB is configured to step between the emulated
code and the 5370's front panel, so you can add functions to the
front panel at will.  Currently, the front panel allows you to
set things like RESET, halt, IP addresses, masks, etc...

In the future, I can foresee replacing the 6800 firmware with
custom C language routines and making the 5370 really sing!

Your limit is pretty much your imagination.

Oh, did I mention?  It is on the ethernet with a full linux IP
stack and firewall!  Plug it into your router, and you can load,
read, fiddle, and do just about anything far away from the actual
5370.  I routinely send upgrades to my 5370 from clear across the
building!

That is just ... cool. But I thought of a way to do the same thing without
the rope and mechanical parts. I figured I can replace the ropes with rows
of LEDs. Then I can turn on the LEDs to simulate the white rope and turn
them off to simulate the black marks. Now you don't need the bearings and
stepper motor. Pretty neat idea, huh!

It's art, after all..

Maybe the huge pile of rope is part of the art?  Like the threads of 
life that the 3 fates decide to cut.  Or if the rope/thread gets tangled 
and jammed.  And the fact that the machine cannot go backwards.



There is a mention in the write up of the whole order out of chaos

I think the realization that it takes thousands of feet of bit-serial
crafted rope, is part of the art. Just IMHO.

Something like the core rope fixed memory of the 60's,
http://en.wikipedia.org/wiki/Core_rope_memory

Many industrial machines internally still emulate the infinite paper tape
loop concept from 50+ years ago when CNC was new. Young guys who have
never programmed that way may not appreciate how programming with zero
cleverness is in itself clever (making it far easier to predict performance
etc. even though the performance is going to be low.)

However, I vaguely remember when we were starting
work on the 5071A that the reason why we used
the model number 5071A instead of 5070A was that
the latter number had been reserved for a hydrogen
maser that was never sold.  The person in charge
of checking out model numbers used to complain about

 As far as I know, those satellites never made it to orbit ?

Re: [time-nuts] 5370 processor boards available

2014-02-24 Thread cheater00 .

Hi,
I browsed the page and the GitHub repository for a while, and read the
readme and read-more documents, but I still don't know what it
actually adds.

Perhaps it would be a good idea to document this?

Cheers,

 As one of the Beta-testers I can highly recommend this, it really gives

 The potential for future improvements is also virtually unlimited:

 How about hooking up an LCD display and calculate and show allan
 variance in real time ?

 Thanks a LOT John!

[time-nuts] new gps satellite prn30 svn64

2014-02-24 Thread tom jones

I discovered today with one of the online sat trackers (www.n2y0.com/?s=39533) 
that the new gps is in a 12719 mile orbit 

above earth. Putting it in a basic gps orbit all ready!

There for I must conclude all the frequency drift I've been raving about is 
merely doppler shift!
And not relitivistic gravitional effects!

Anyway it looks as if the atomic clock on this  new satellite are keeping 
excellant time.
.037ns over 12hrs 
.011ns over 36hrs  
.018ns over 48hrs

My estimation of the stability would be near 2e-16 ??
Someone else might want to pull out the calculator and check me on this.
(to lazy to pull out my own calc. after all the cutting and pasting hehe)

My first reception was at 23:32:22pdt

Re: [time-nuts] A small piece on HP's hydrogen maser in 1968

Worked fine for me earlier. May want to try to dump your cache and cookies.
That seems to help when things get silly.

All of that said and back to the numbers. That would have been way back in
1968 and there would have been artificial gods that controlled the numbers.
These odd folks still exist or are the sons and daughters of the number
gods. But today they use excel and color thing red yellow and green and
haven't figured out that you can expand the cell to hold more numbers.

Tom, the most common fault with these is the thermal fuse going open

When there are extraneous characters and a line feed added by some word

1) Forward the email 
2) delete the extra characters, getting the proper URL back
3) Copy the URL to the clipboard
4) Open browser and paste URL in

After that, trash the forward email.

Re: [time-nuts] 5370 processor boards available

D
I can give you some insights here. Others will be more effective. We all
agree that the 5370 frequency counters are great devices from 1980. Right
there is the first issue. The old micros are getting old and failing. I
have lost both 6800s and eproms.
Thank heavens stuff is still available.
But this board replaces those items completely. Welcome to 2014. Now we
just have to worry about big fat capacitors.

In addition it gives you remote control other then GPIB. We all love GPIB,
but us lazy types like Ethernet better. Cables are easier to manage.

Finally the crazy thing is it gives you web services. Wow for a 1980s box.
All while leaving the front panel operation intact for simple quick
applications.

The only thing that can be annoying is there is a shut down procedure for
the unit now. It used to be power off.

All of the above for $90.
Hope that helps you.

Paul

Re: [time-nuts] FE-5680A sweep range setting

2014-02-24 Thread Paul Berger

A couple further observations, to make life easier when adjusting C245 
you can unplug the top card and move it aside, the CVXO will lock 
without it, but you will not have the 10MHz to monitor, but you can 
monitor the CVXO output instead.  On the 6 pin connector you will see a 
1 near the outer long edge of the second card, the CVXO output appears 
on pin 5 of this connector and on mine, it locks at 50.25505808 MHz 
according to my 5335A.   I also noted that when the 5680A is well warmed 
up it sweeps through a much smaller range.


It would appear that the one I had trouble getting to lock has some 
secondary issue.  I can get it to lock playing with C245 but the when I 
power off and back on it seems the  CVXO does not start properly 
measured frequency is low and outputs a very weak signal, injecting some 
capacitance by touching a metal screwdriver to the end of one capacitor 
gets it going and once that happens it will lock pretty quickly more 
investigation needed.


Paul.

Hmmm, it does affect the range (twitchy is an understatement!) but 
still no lock. To be continued


Now by the 'frequency control board' do you mean the board that 
overlaps the top of the D-Sub connector? I have been at a loss to 
understand this section. There is all sorts of silicon on it but no 
inputs of any kind. Just a 5V supply and a single analog output of 
1.99V on the orange wire. I'm baffled, so if you know what this board 
is doing, please tell!

Re: [time-nuts] 5370 processor boards available

2014-02-24 Thread cheater00 .

Thanks for the info.

It could still be power off... just add a large capacitor as voltage backup
and make the unit sense when power is off. It should be able to shut down
quickly enough. That's how it works most of the time. Alternatively add
some 1.5v batteries and a charger. That should never run out.

Running a PC without backup power is asking for trouble. A few 1.5v
batteries and a charger and buck-boost cost only 10 bucks.

Going to leave the battery comment alone. Most people with HP and other

poorly designed charging circuits. Even HP did the resistor diode thing.

Re: [time-nuts] 10811-60111 needs repair

2014-02-24 Thread Tommy phone

Hi Dan ...
Thanks for that info; I wish that was all it it but I have bypassed the 
tiny(amp-wise) fuse and that did not help anything so i have concluded that 
there is more wrong, like maybe the oscillator circuit has a problem.
Part of reason is that my time is limited us I have poked into it far enough to 
see that further damage caused by me is more likely than repair. As Dirty Harry 
Callahan once said in a movie, a man's got to know his limitations. 
Thanks for the suggestion.

 Tom, the most common fault with these is the thermal fuse going open circuit. 
  If that's your problem then fixing it yourself might be easier than sending 
 it out...
 
 I had one with a dead thermistor; that was a little bit trickier.  A lot in

http://www.hp.com/hpinfo/abouthp/histnfacts/publications/measure/pdf/1968_09.pdf


This broken link business is very common in some browsers (in Windows).

It's because there's an underline in the original URL. When the browser 
sees a link it underlines it in blue, which converts the underline into 
a Rich Text or HTML graphics character.


The simple cure is to cut and paste the URL into a text file with 
notepad. This gets rid of the fancy format characters.


An even better way is to switch off HTML and RTF if you can.
Email was meant to be text.

That was my experience with XP and IE 8.

Downloading began at once and the byte counter rolled on up to the
target in a minute or so, but I couldn't read the document. My network
indicator stayed lit, and Properties showed message flow, so I did
something else and came back to find it done.

Has happened once or twice before.

Great articles in the result, though.
