Thought I'd ask the group:

I'm looking for a source for the C-clip "speed nuts" used in

Agilent/HP

equipment rack rails, such as in the N4043A ( nee 1181B ) cart.

The part is an

Agilent PN 0590-0804 "NUT-SHMET 10-32-THD .5-WD STL" and is

a "support part for

which Agilent does not own the design specifications" (which I read

as

available off-the-shelf someplace).

Agilent wants 3.38 each (!) for them, and I suspect you guys who

work with

rack mount equipment know an online hardware store off the top of

your head

where one can buy a bag of them for something less.

Thanks in advance,

I need the wiring for the plug on the back of this unit.

Hi All,

Just picked up an HP 651B and have a few problems.

For one thing the unit seems to be extremely sensitive to the "band"
selector switch, and the 10MHz range in particular. Switching to it
results in flatline output, with jiggling finally getting it going.
Can anyone with experience with this unit offer any advice? Is this
a dirty switch contact, or am I looking at an issue where the osc.
does not start up.

This unit looks like someone besides HP has been inside with messy
soldering and melted insulation! Scarry!

A source of an electronic manual or "copiable" manual would be
greatly appreciated.

Thanks for your time,


Mitch

BTW, these use the COOLEST display decoders!!!

Hi group. I have a couple of old Nixie display counters. A 5214L, and a 5201L. It did take me a while to figure out the '14, but now understand what it does in all its modes. The '01 is similar, but with the addition of a PHA (Pulse Height Analyzer). Can y'all explain this? Perhaps it's just a fancy name for a calibrated trigger circuit?

Hi there,

These TO220 packaged schottky diodes seem fairly common in switch mode
power supplies used in photo copiers

Also in computer power supplies.

These TO220 packaged schottky diodes seem fairly common in switch mode power supplies used in photo copiers and such now. I don't think you should have much trouble finding a replacement. Perhaps you can find a junked copier to get one from. The schottky diodes are fast acting and have less voltage drop than silicon.

Hello Tom,
Motorola did a lot of Schottky and ultrafast recovery diodes in TO-220
packages. Those were diodes for currents higher than 5 A and to best of my
knowledge, none of them were JEDEC registered, so most likely single source.
I have seen some other manufacturers putting out diodes in TO-220, but very
few of them, not an industry wide practice. Some of those diodes were pairs,
and others had tab connected to one of end leads. What you have is either a
pair with one leg shorted or it is a bona fide single diode.

As Schottky diodes, TO-220 was used up to 30 A and for higher current they
used TO-218 (a bigger package). In ultrafast recovery the line was drawn at
16 A.

Hope, this helps somewhat.

Hi, all.

I need help identifying a part on the power supply board of an HP
3325A.

It is CR10. But it resembles a TO-220 transistor.

There are three separate part numbers on it: 1) 84-0266 (top of front
of device), 2) 8515, preceded by what looks like the Motorola "M",
inside a circle (bottom of front of device), and 3) 136725, printed
on the top of the device.

Terminals 2 and 3 (left to right, from front) appear to be shorted.

And if anyone has schematics, or a service manual, that's already
scanned or photocopied, I would be very interested.

Thanks!

Hi all,

I've got an HP 3469B multimeter that's not behaving as it should -

the

display is behaving sensibly, but the values bear little

relationship

to the electrical signals applied.

Thanks,

Hi, Yes there is a manual. My copy is bearely readable. Came from
HP microfiche... Check the solid tantalum capacitors on the second
board from the top, after removing the top cover, with power off.
The same capacitor was shorted on both my 3469A with weird results.
There are no labels on my PWB.

Ladies and Gentlemen:
Welcome to the new hp_agilent_equipment group. As one of our first
posts, I am asking if anyone has a schematic for a HP 4328A
milliohmeter. After serving me for many years, this instrument
went "full scale" and will not respond to inputs on any range.
Any .pdf file would be appreciated to get me back and running again.

Many thanks for your help -- Tom Leedy

Hi Tom,

Contact me by email below. I have a working 4328A and a manual. I
can scan it for you. If it whent full scale it could be the batteries
or the probe wires.

Regards Daniel, ddufresne@...

I recently wrote a program to allow PCs to control and print
waveforms from the HP54200A. The program also allows waveforms to be
averaged to reduce noise and improve resolution, and it does FFTs.
It is written in Delphi 7, but can probably be modified in recompiled
in earlier versions. It has been uploaded to the files section for
anyone to use. However, you must have a National Instruments GPIB
board in your computer, with the correct drivers, and a cable, of
course. I'm working on a new version for the HP54542A, but I'm going
to try to keep it compatible with the older version. Please report
any bugs to me.

Hi,

I need a copy of pages 7-3 and 7-4 from the HP3320A/B op/service manual.
Page 7-3 is the block diagram, and I don't know what is on the back
(maybe it's blank).

A scan would be fine also, or if you could part with the page for a few
days, I could copy & return it.

I'd be happy to pay expenses or whatever seems fair, trade another manual
or parts, etc. etc.

Any help would be appreciated!

Thanks,

David DiGiacomo

can it

be that my rubber has just spun around hiding the hole?

Yes it did spin around.........at first try it would not
budge......second try after posting the original query found that
more might was needed in the effort and lo and behold it did move and
turning it 355 degrees still showed no hole, the last few degrees,
and lo and behole.....there she be!
