HP crystal Osc
 

What possible use does a HP 10811-6011 Crystal Oscillator have in a
homebrew project. I came across one of these but don'y really know
what to do with it. I hate to toss it out.

Makes a good house standard to calibrate your receivers and test equipment.

Try google search engine to see how others use it

These oscillators are much more stable than TCXOs used in ham equipment,
but they are not always directly comparable. A TCXO will be stable from
the moment it's powered on, while an OCXO like the 10811 will be very
far off frequency until it warms up, which may take 2-3 minutes.

Most ham applications do not need the extra stability offered by an
OCXO. Test equipment is the primary application for these devices.

If you toss it out, feel free toss it this way. :)

Some the guys around here use them on 10 GHz SSB.
You really need that kind of stability for that mode.
A TCXO is 100X worse. Another popular use is as
a "flywheel" with GPS, to get a very accurate frequency
source. Search on "HP Z3801" for info.

(I worked at the HP division that made these for 19 years.)

One of the great things which the telecom bust did was to make the equipment
you designed at HP available to us experimenters -- I use my HP3586C
Receiver's ovenized oscillator to drive my HP5334 frequency counter and
HP3336B Synthesizer. I never dreamed I could have afforded this type of
equipment until EBay made it possible.

I was the project manager of the 5334B frequency counter.
It had an option to have a 10811 timebase. The standard
timebase, which I inherited from the 5334A design was
embarassingly bad, barely able to do 10 PPM. Unfortunately,
you cannot retrofit a 10811 to a 5334, because you need an
extra PC board. This board is required to be able to put
the 10811 on its side, because there isn't enough height for
it.

The gray market in used HP/Agilent test equipment is
really hurting Agilent in some products. My old division no
longer exists. I now work at Agilent Labs.

Interesting. Could you shed some light on the timebase used in the
8566B and related analyzers circa 1984? The one I'm looking at doesn't
appear to be the standard 10544 or 10811 unit. I've never run across
one of these before in any other HP instruments. Is it just a
repackaged 10811?

Rick,

The 10811 that I have has a decal on it that reads "upgraded to series
3010". Do you know what that means?

thanks,
Lefty

Used equipment is NOT a "gray" market. Anyone who buys an
expensive piece of equipment is entitled to sell when they no
longer have a use for it.

The various versions of 10811 have part numbers
of the form 10811-6XXXX. There are a few dozen
varieties. I've never heard of "series 3010" in reference
to 10811's.
