Re: HP8593A Power Supply repair

 

Roumen,

????? I would like to have a copy of the power supply schematics if it is possible.? My HP8591A has the low 5.2 volt supply problem that others have mentioned.? I am very experienced in this type of electronics and I would like to find a solution that is lasting and that I can share with others.

??????We have a family friend in Burgas and relatives in Russia, we are in the US.

?

How about the workhorse 3478?? Very popular and as low as $150 guaranteed working on eBay.

?

PS: My stable of HP DMMs is a 3456, 3457, and 2 3478¡¯s.

Hello All,

I am doing a bit of research to accomplish a comprehensive understanding of the DVM / DMM technology from the late fifties and early sixties into the 90's. ?I have come up with what I think is a list that covers the models I should be looking into. ?Are there any more digital meters that should be added?

Re: Replacing ROMs!

 

Didier has done a great job with his site, then again it is always a good idea to have data in more than only one place at a time, the IT world MTBF is likely lower than the human one.

You are missing the 3480.?
Do you want to include companion units like the 3495 Scanner ?
I worked at the Loveland Instrument Division, LID, on voltmeters from 1969 until 1975 on various projects.

Yes, the 3458A should definitely be in there:

I am trying to stick with one company at a time first, then I will need to branch out to the other quality makers to compare and learn. ?I know the 405 was a commercial flop relative to the 3440 and that there were a few key players early in the game, esp.

I am finding it quite an interesting journey so far.

Any thoughts or ideas or memories would be great.

I have located most pertinent HP Journals, App Notes, and Catalogs so the easy part is done. ?Now it is time to dive in and see where it takes me. ?Thank you all for your input!!! ?Keep it coming.

Re: HP DVM / DMM technological history

 

I don't know if you want to include them, but there were also some scopes including the HP 1715A and Tek 465B that had digital multimeters glued to the top.
Re: WTB 3 Pin Socket for Probe Power

 

As a quick update - if you are in the UK there is an 1122A for 50 quid or best offer on a well known auction site or one for 63 bucks if you're other side of the pond. Not a totally silly price for a well built complete power supply in a handy box ready to go?

Perhaps you might think that, but Didier's site has a ROMS
section which aspires to have ROMS for just about everything.

Re: WTB 3 Pin Socket for Probe Power

 

The connector had some discussion on : >>> <<< some time back. It is available according to : >>> parts.agilent.com <<< then, find by part, part number, 5060-0467 Only $36.57 plus tax. Or find a trashed HP 1122A PROBE POWER SUPPLY. Sometimes ebay listings are reasonable.

I drew a blank looking for these a while back, I deduced
from the data in my 8553B manual that it may have been an HP
proprietary part as it's HP part number 5060-0467 and
its manufacturer part number are the same with a
manufacturer code of 28480, which is - you guessed it - The
Hewlett Packard Company of Palo Alto CA!

Now I suppose it could be a variation on some existing
design from a third party and was just special to HP because
of the color of the plastic or something and I do remember
that RS components (Radiospares as they then were) sold a
two and three pin connector that looked very similar back in
the 60/70s but who made it I don't recall - if I ever
knew!

How's that for a not-very-useful post? Perhaps it will
jog a memory on the forum though?
