So... My HP3336B has TWO HP S/N plates...
The original plate: 2514A0
and a secondary HP sticker with: 2127A00xxx
Also there is another HP sticker with: 3040L SYSTEM
Anybody have any clues on this??

When a common HP instrument is sold as part of a
system, HP would often give the instrument two badges.
One was the common instrument badge, and the other
was the system badge.
In your case, your HP3336B was sold as part of an
HP 3040L system. (Whatever that was). Usually, there
are also some
Hello all...
I can't find my WECO adapter for my HP3336B. It got lost
in the move a while back. ;-(
Am in need of a WECO to BNC adapter, WECO 439A/440A
Anybody have one that they would be willing to sell?
TIA...

I bought a WECO adapter when I got my 3586B.
Turns out there at least two WECO connectors and I got one that didn't fit.
So I replaced the 3856B input connector with a BNC jack.
Problem solved.

later sticker 2514, remanufactured or modified to special customer

Hi Stan...
Funny thing about the labels...
The 2514 label is the style that you would expect
on a piece of HP gear. Shows the AC input setting
and other info.
Both the 2127 and the 3040L System labels are narrow metallic
labels, with the HP name s/n info and nothing more.
So I don't

Thank you for your recommendation I use Wenzel extensively as a matter of

OK, good that you are familiar with it, it was not obvious in that message.
If you consider it as the first stage, and that you then can put another

How much of an improvement does the LTC6957 give over, say, a simple
74AC gate?
Actually, is there a list of different techniques and the performance of
each? I know that the LPRO Integration manual gives some good info for
phase noise, but I'm not aware of a similar document for slew rate

Hard to predict without looking at the details. The main battle for a
sine-to-square is to fight white and flicker phase noise as well as
additive repetitive signals such as 50 Hz power noise creeping into the
jitter. At the same time we try to get the conversion more long-term
stable,

Been watching this thread today and am curious. I know little of these WECO

That is correct. They are designed for a telephone system patch

They are 75 ohm, and designed to handle large numbers of connect/disconnect

Hello again...
Late this afternoon I decided to go looking for the WECO/BNC

The last place I looked was where I found the adapters. Yes, plural!!
I had bought a half dozen of them about 10 years ago!! ;-)

I disobeyed the group suggestions about antennas, and bought one of the

I'm a bit confused about what you're asking. You discuss antennas but you show
pictures of a GPS receiver. They're not the same thing. I use a puck antenna.
They cost about $6 on ebay, and take their power from the coax. Normally your
GPS receiver supplies power to the coax, so you don't
