I just ordered the book on Amazon. I have always admired HP's ethics and methods. I interviewed for a position as a sales engineer in the 1980s but did not get the job; too bad.

Hi Thomas

Thank You

I just found a nice 6 page description on BAMA Mirror. So problem solved

Kind regards

Its a simple diode mixer with 1N23 in a coaxial structure. I can't remember what is was part of, could it have been a early spectrum analyzer?

Re: 8920a attenuator change

 

Normally it drops off at around 10 Mhz ...note the unit will operate down to .24 MHz but the input and output levels will be off below 10 Mhz.

Typically the 8920A had the mechanical attenuator ...must have been a very late if not Agilent badged version if there was such a thing.? ?IIRC the production had switched completely over to the? B version when the Agilent split happened .? Not sure the production went that long into the Agilent era ....most of the 892X units out there are HP badged .

The short answer to your question is NO

The module change needed is the RF input and you have to have the tuning data on that module ....really the only one that's all that critical.
Easiest way may be to just trade that in a an option 55 8920B or? an 8920/21A? that has the right input.

I do have some? of those in stock.
Re: Cheap and simple OXCOs upgrades on ebay

 

Bill and Dave have been spinning in their graves for quite a long time. Once the CEO's of the company were not chosen from long term HP employees that lived the "HP Way" that started the downfall. Carly was the worst! Read the book "Bill and Dave" by Michael S. Malone and you will get the entire picture.

Re: Another 3GHz 53132-68003 Chanel 3 option design for the 53131A and 53132A

 

Ok, so I whipped up a test board tonight as I got the PCB's delivered yesterday.

One small hiccup... I accidentally ordered an older revision of the PCB by mistake (because I'm an idiot haha) so I had to get creative to get some of the parts to fit.....
The good news is that it is now working! :D

So far, I have only tested it to a tiny bit over 1GHz from my Tek SG504 levelled Sinewave Generator, but using that and my SG503 levelled sinewave generator for the lower frequencies, I have verified that it currently works from 15MHz up to 1.05GHz over the entire input voltage range of 0.5V to 5.5V peak-to-peak. Not bad so far...

It does exhibit the expected spurious readout when there is no input applied, but playing with the bias on the prescaler chip inputs is a job for tomorrow. It's late, time to sleep happy with tonight's success. :)

Re: Hp 35650a 50 kHz Dynamic Signal Analyzer

 

I have uploaded the last-known versions versions of the 356xA software into the files section, for DOS/Win31 (3.05) and Win98,NY, XP (4.04)

Peter Brown's documentation uplaods look pretty complete on first glance. I'll be comparing them to my full set of manuals in the coming days.

Some interesting history:

The hardware was designed by Kit Ling of VTI Instruments. HP did the software and debugging in-house (Loveland, IIRC). Kit also designed the VXI versions of the system, which pretty much killed demand for the PC version.

Years ago I had an email chat with the fellow who led the debugging team for the 356xA (3566A, 3567A, 3565S) systems. He described being set up in a room with different OS's and several instruments they expected it to be used with, with instructions to find bugs and basically try to break it. He recalls doing this for 3 over months before they released the product!

I use the system with the HP software, both manually and under DDE control from HTBasic. It is a very flexible system and uber-reliable. You can use the SDF Utilities for data conversion, and the HP 35639A software to create custom graphs.

Re: hp 5036A Microprocessor Lab

 

Hello Steve,

Yes, I saw your unit on your webpage. Quite often I visit for questions about gear. Glad you have it up, it is an invaluable resource.

Once I manage to find one from either a responsive seller, loony prices, or one that is not total junk, perhaps we can trade notes. I've been scratch-building an i8085 system for an innovation project I have been contemplating for some years and looking for the 5036A as:

1. A sanity check for the scratch-board,
2. A way to gain insights how to best use my 5005B Signature Multimeter in terms of data signatures passing bidirectionally through the I/O during phases of the runtime. The HPIB will help in providing me analytics. Using EZGPIB with the Prologix module.

Many of my colleagues think it crazy that machine learning can be accomplished on such a small system (small in terms of the sheer computational power thrown to LLMs) but I did some scoping years ago on a M68HC11 that yielded favourable results. Writing a paper for IEEE Aerospace Transactions to share publicly.

If I can make this work, the next generation would have a reason to continue to engineer these kinds of solutions.

Hi Christopher

I have a 5036A with Manual.

Not for sale though. I use it occasionally as a test bed and intend to teach my grandkids about microprocessors, if they are interested!

All,

For a research project, I am looking for an hp 5036A Microprocessor Lab. Working (and intact) would be ideal.

I am also on the lookout for the manuals and the 500-page training guide in paper format. If anyone could help with this request that would be most excellent and highly appreciated.

Thanks in advance.
