Thank's Erik I appreciated the information very much.
I m still a fan of the old measuring HP equipment:).

Never had an instrument in my lab that has such a noisy fan.

Beeing designed for rack/industrial use, the noise is probably normal.
Many years back I had a Sun 2 (2/120?) server in the lab, that
really took some beating. it was about 12" wide, 24" deep and 36"
high, and fitted with (IIRC) thirteen 5" fans, six in the power
supply alone. It was noisier than being in a tube train on the
Circle Line!

hp 15 pin card extender

 

im looking for a 15 pin card extender
for trouble shooting a hp 310a wave analyzer
its working but still has some "issues"
and it would be nice to be able to scope
the cards
i fixed it so far by finding bad capacitors
with a meter "some of the small lytics were shorted"
and carefully tacking in some miniture lytics to replace
some twistlocks that have high leakage current in the bridge
drive circuit "active filter"
does anyone have a pdf of the manual for a late production
310a??
HP 70001 mainframe

 

Hello HP specialists and others ,

My 70001 mainframe has such powerfull fan's , (BEARINGS are OK!!!)
that the noise equals my Nilfisk Hoover (Brand name's , suppose you
all know what i want to point out)

Never had an instrument in my lab that has such a noisy fan.

Beeing designed for rack/industrial use, the noise is probably normal.

I noticed earlier 70001 instruments had NTC's to reduce the fan
voltage (and noise) , anybody has schematics or basic design that
was used ?
The printed circuit still has the unused space/circuit where the NTC
have to be located , I can see place for 2 ntc and 2 resistors (one
set for each fan ) and 1 in front probably for extra safety that used
to be there in earlier design .

The 70004 display mainframe that can be used together with the 70001
is designed very very silent ...

Many thanks,
Erik
Re: Workbench surface

 

Hi Steve,

To see what you are dealing with, turn on your oscilloscope, set its sweep
speed to 10ms/dividion, set its vertical deflection to 0.5 V/division, and
with one hand, grab the tip of your scope probe.

That signal on your screen is real, and has enough current to drive a 10 meg
to ground load. Now, imagine what that signal would be if your load
was 100 meg, or 1000 meg to ground.

Oh, and it doesn't matter what kind of lighting you are using, this is stray
coupling to the power line. If you use mains electricity, it is there.

so some static can dissipate before you get to the mat. Like a 3m area which
is floor treated, floor mat is ideal but I find that carpet is ok if its treated twice a year with some spray on static treatment.

d. If you are handling a lot of very sensitive devices in most other places in the lab
where they might be stored but not worked on then a static controlled fan might
be helpful, cant recall the name but it has a ion source either mildly radioactive
or a power operated type. I dont use one myself but depends what you are handling,
others might comment on that.

I'm planning to replace an old workbench. Is there a top I can put on my new workbench that is ESD safe? Right now I have an ESD mat that I place on the workbench surface when appropriate.

Inasmuch as I'm going to be more or less starting from scratch, I thought I'd at least ask the question about an ESD-safe work surface.

Thoughts or advice out there?

Thanks.

Sorry my last message was mysteriously truncated!



HP has a Firmware Upgrade (08560-60090) for 856xE



;
844&nid=-536902966.536881691.02&id=475844
<;
5844&nid=-536902966.536881691.02&id=475844>



From HP support:

---- Needed for last versions of TAM

---- Fixes FADC bug
---- Fixes SIG ID On/Off and zero span amplitude jump

---- Year 2000 bug fixed

---- Status part is UTG (no more kits)



Did somebody have EEPROM files for this upgrade?





My configuration is: Spectrum HP 8564E + Tracking source HP 85645A



920427 EPROM on tracking source HP 85645A

970326 EPROM on spectrum HP 8564E



First draft page on 8564E:

This configuration works well (you have to configure as 8563e in
tracking, 64e not in menu)



I have many documents and notices + clips for exchange, read:

Microwave Mixer

Hi all. A bit off the HP theme, however need some help. I have a Time
63132 rf (active) mixer. It also has an alt. part number of DXM602. The
LO and RF appear to be in the 10-20GHz range. If anyone has, or can
direct me to where I can find specs. on this unit, I would really
appreciate it.

Re: deskjet 895 cxi printer

One stock fault in HP printers is the print head slide bar becoming sticky. That's the chrome rod about 1/4" dia that running across the printer. Try wiping it clean with a tissue, that usually clears the fault. It shows up as all kinds of errors.

I forgot to mention that it was only a real problem because it was quite low
over the bench and the cables to the lights wound around the back and side of
the bench, plus they were the old inductor type ballast and the large metal
housing might not have been well grounded. When a 20v max mosfet gate
regularly gets 27v at 50hz it doesnt last long but all other ICs were ok,
a drop in the mat resistor to 100k didnt upset any other handling and
dropped the field voltage from 27 to around 2.5

I will take a look at 3M and other mats, both for the floor and the
bench top.
Ah - I just checked my post, the '3m' later on referred to a 3 metre area
of transition (miniumu) from an unsafe to the fully safe area. For me this did not
need a 3M mat just an ordinary wool/cotton carpet which was treated with the same
chemical women use when ironing to stop their dresses sticking to their
panty hoses - it was *much* cheaper than the 3M or any other chemicals, I
actually still have a Bokhara Afghan rug, cost about $600 in the olde days when
these were being sold as "investments", still in one piece must have had it
for over 20years now, more utilitarian than worth hanging on the wall for a seance ;)
From what I recall, the chemical is just some ionic salt, perhaps even MgSO4 or
maybe some mix which was very slightly hygroscopic, or at least had some lower
resistance when dry at low humidity levels cant recall exactly. I dont
use it anymore as my smallest lab is for my use only and if I ever have any
very badly static sensitive devices on that 3M bench then my whole demeanor
changes dramatically :P

Cheers

Mike

Good site for that type of issue is . They

Re: HP mms system catalog

 

Hi Erik,

You can find a copy of "Modular Measurement System HP7000 Family
Catalog" at the TestMart website ( ).
At the bottom of the page, you will see a section called: "Library".
In this section. click on the link: "Original manufacturers' catalogs"

Now, in the Agilent catalog listings, about 1/3 down the page, you
will see the "Modular Measurement System HP7000 Family Catalog" link,
where you can download the document.

The website has a registration procedure, but it is very easy. Good luck!

This is another product that I used to work on during my days in

Along the same lines, might there be a copy of the

Re: Workbench surface

Rasputin Novgorod
 

The only solution is to follow a good protocol. I put that in place
after I
destroyed a rare double FET while repairing a 'scope.
After several careless incidents with soldering irons,
I started using fireproof table tops (with static mats
on top). It was some kind of laboratory table-top, a mix
of asbestos and resin, that was made locally when I lived in
New England. I've had them for 20 years. I remember the
factory cutting room was clouded with airborne asbestos and
cement dust; nobody wearing masks. The safety inspectors
wound have had fits...
