Dear Chris,
Thanks for the advise. It is always nice to have different opinions
and points of view.
I have heard about the dependability of Efratom products while doing
my research homework. An Rb oscillator like that surely could be a
good bet considering your vision of the plural concept of oscillator.
I agree. As in many of my other scientific/tecnical projects, I
usually do not feel that all of my bases are covered with only one
brand or example of any of the items that I so much enjoy as hobbies.
I will seriously consider your kind advise and look forward meeting
you whenever visiting Rancho Palos Verdes, as I usually do, in the
future.
Kind regards,
Edgardo Molina

Dear Chris,
One of my needs: A dependable Rb source. HP appeals to me as most
of my
electronics lab equipment comes from that house. I have seen
numerous other
Rb sources here and there but would like to afford an HP unit. I
know I can
go to the party driving either a 60's VW beattle or driving a 60's
Ford
Mustang. Both of them can get me there. Still personally, I rather
drive
the V8 beast. The robustness, mechanics, physics package
characteristics
and form factor, homogeneous with my HP quartz frequency standards
and
frequency counters is what catches my eye when looking at that
model. Let's
say 50% looks and desire and 50% for what it is. It will be used in
my time
and frequency lab. Hobby use, a learning tool, an object of desire...
OK that is a reasonable use, you just want one. But the Rb units
on
eBay are much more resent manufacture, better secs and well under
$100.
But no "HP" name plate and you must apply the DC power. They score
near
zero in "looks" as they are just the bare oscillator.
Look at this eBay number: 300719752578 It is a very good unit from a
seller many people know. The specs are very good.
I bought one like this back when the price was $39 shipped.
300606871861
Mine is preforming very well. It provides a reference for a a few HP
Universal Counters.
But really if you are setting up a lab at home the first thing you
should
buy is the Thunderbolt and a good antenna. You will need one to
calibrate
your Rubidium oscillators. (yes "oscillators" with a pleural "s".
how
else to cross check them if you have only one?)
