HP8558B Versus HP182T Sweep Fail.

Good year 2022 without the accursed bug.

Well there everyone

?

In April 2019 my HP8558B decided to let it do the sweep? Fig0 , I found that only with external sweep it worked, it was on the waiting list for a better analysis, however I was around the HP8116A and with external help I got there (well there Markl).

In December 2021, in a visual inspection of the HP8558B plugin, I found that some of the contacts (fingers) of the 4 switches were loose, and I thought it was here, and the novel that I summarize below began

Preliminary Notes: Understanding certain details implies access to the HP182T/C Service Manual.

I urge HP experts to speak up.

?

1st 2019 I lost the HP8558B scan Fig0

2nd 2021 I considered that the failure was due to lack of contact finger in the SW. Fig1 and Fig1.1 , ward work.

3rd mechanically fixing the fingers of the SW Fig2

4th Malfunction remains?

5th Test of the switches all OK, with the help of a kit adapted from the IC card HP10529-20005 Fig3 and fig4.

6th Why not use my HP180C+HP1802 and HP1821A that is stopped !! fig5 , because I haven't used it before ?

Test with the Main Frame HP180C and the HP8558B, after de-rusting the switches and adjusting, voil¨¢ HP8558B OK!!

7th Use 182T with HP1801 and HP1821 OFF, I confirm the failure is in the HP182T.

8th All voltages on HP182T OK.

9th Summary measurement of transistor and diode junctions (all?) OK

10? Measurement of HT -3KV ?? and 19KV ?? , result? +-2.9 and +-? 18KV, OK

10th Use of two 1V 100 Hz sine wave generators for input on the HP1801A and the EXT INPUT sweep on the 180C

11? Results in a distorted Lissajous image by pressing FIND BEAM Fig6

12th With Intensity CW almost at MAX. clear image Lissajous Fig7

13th In sweep INT values of UNBLANKING GATE board A7 pin14 is -0.2V should be -0.7V

14th Output on board A7 ALT TRIGGER pin13 for Plug-in not detected?

15th UNBLANKING SIGNAL output values also in A7 pin w4, is between +20 and +75V when it should be between +42 and +92V? DC values, and is not a square signal.

16th I'm in a fish situation with is tail in the mouth.

Re: How to find patents for HP equipment

 

Bonjour, some misinformation in a few replies.

35 US Code ¡ì 287 - "Limitation on damages" mentions effect of lack of notice and marking ion patented devices.

After issue, the patentee or assignee shoudl mark the equipment with patent numbers.

Nowadays "Virtual makring" allows a website link to all the applicable patents.


Check the HP manuals of the instrument for a list of applicable patents.

Re: HP 3048A software without floppy disks

 

BTW, you can just ignore the prompts to change floppy disks when asked, since all the files are one the same volume.


Re: HP 3048A software without floppy disks

 

Matt,

If you are already emulating a hard disk using hpdrive, you should have enough room to store the programs onto that volume and not have to use other GPIB adapters.

In looking at the "PHASE" program.? You actually need to STORE the two files "PHASE_SUBS" and "SYS_TESTS" as PROG files so that they can be LOADSUB loaded into the running program (see Installsubs, line 6962).? I would do the following for each of the files: "PHASE", "PHASE_SUBS", "SYS_TESTS".

1. GET the original ASCII program file into your HP382.
2. Do a Single-Step to have the loaded program do a Pre-Run.? Note: This speeds up the loading of that program later.
3. Now STORE the program back onto the disk (For example: STORE "PHASEnew").? Note: You have to name it slightly different since there is already a file called "PHASE"

Once you've stored each program file, you will need to rename the original ASCII versions of the files to something else, so that you can rename the new stored program files back to their original names.

Now you should be to do LOAD "PHASE" and RUN the program.? It should be able to do the LOADSUB ALL it needs to do for the "PHASE_SUBS" and "SYS_TESTS" as needed.

You can privately email if you need further assistance...


Re: How to find patents for HP equipment

 

Matt, consider yourself lucky if you find only a hundred or so possible candidates to search through, for patents pertinent to a particular model. The first thing to look at is the manuals for the product, preferably versions over some time or generation span. Any patent notices would be in the manuals, or even printed on the instrument itself, in a form like "this product may be protected under one or more of the following US Patents..." No one in their right mind seeks patent protection on only one particular product - you claim as broadly as allowable an apparatus, a method, or both, for accomplishing a purpose. Any patented inventions used in a product could have resulted from its development, or from another product prior, owned by the same entity. This means that some patented circuit design (apparatus and/or method) or software (method) used for another model (of anything) before, and adopted by the 8662A, still counts, which makes the possible list even bigger in number and time span.

Your searching by assignee and rough time frame makes sense, but as you suspected, there's more to it. I'd recommend considering this list of things to do:

1. Look for any patent notices in the manuals, on the unit, and in the catalogs or other promotional material.
2. As you mentioned, the contemporaneous HP Journal issues are good for timing, but even better for the technical info. I've found these to be among the best sources - they seem to have been written (I think) by the engineers and others who knew exactly what's in there and why, and even explained the issues and rationale for decisions made.
3. Look at earlier/similar products in the line to get some idea of what may be in common. Look at other products that seem might need some of the same. And, look at later products that may do the same or better in some respect..
4. Learn to speed read the Abstract, looking for key words and phrases that may be pertinent. Also, with practice, learn to speed read the first paragraph or two of the Background and the Description, and Claim 1. The Background may mention similar or competitive products.
5. On any that seem interesting, look at the prior art references listed, and at any later patents that reference it. - you may see some connections.
6. Build a list of the inventors of anything pertinent. Then search by these inventors.
7. Let your intuition loose. It may lead to wild goose chases, but you never know. I've found lots of things by sheer luck or serendipity - these are unreliable and unpredictable, but great when it happens.

Remember, you'll almost never see the actual model number itself show up in a patent - it is intended to be broadly applicable, not limited, and a model number may have not even existed anyway at the priority date and throughout the application process. What may show up is what it's supposed to better than - the prior art. Or, in patents that reference it, and why they are better in some way.

Good luck.

Hi Pete,

In the US, it once was "first to invent". That is no more; it is now "first to file", in sync with (most of) the rest of the world.

Re: How to find patents for HP equipment

 

In trying to find patents that apply to specific models, I¡¯ve found that the HP Journal article that introduced the instrument to be helpful. Knowing the names of the author and those he acknowledges gives you a helpful starting point to narrow the patent search.

Re: How to find patents for HP equipment

 

USPTO does offer PDF copies of patents but you are right that Google has better search facilities. There is also another search engine which has European patents on it but I am not good at working it and don't have much detail. Because I am interested in the history of technology (and other history too) I have gotten reasonably good at searching out patents and reading patentise. Some patents are written to disguise as much as possible the exact information they contain, others, for instance Kodak patents are relatively clear an often have a lot of useful information in them.

On 2/21/2022 4:59 PM, Brooke Clarke via groups.io wrote:
Hi Pete:

There are a number of ways.

In general there are two search engines.? The USPTO and Google.

The good news is that Google has used Optical Character Recognition (OCR) and so you can search all of their data base for any word anywhere.
The bad news is that Google has used Optical Character Recognition which has many mistakes, so there are odds associated with any search.
<> - this is the basic patent number search and for United States patent number the first two characters need to be US.
At the bottom of that page there's a link to the Advanced Search where you have a lot more options.
The Google patent result pages can be trimmed back so that they end with the patent number, a very convenient situation.

The USPTO has a number of web pages for searching.? But they use .tif format for the patents, i.e. no OCR and the searches can only be done on the fields they have digitized.
This is the patent number search (good for getting class numbers):
This is the Quick search:
Notice the select years drop down box.? When you select 1976 to present there are many more fields available to search.
When 1790 to present there are fewer fields available.? There was a patent office fire in 1836 so some patents are no longer available.
The URL for a search result is not permanent nor is the result of a patent number search.

ALL patents are issued on a Tuesday.? So? you can check? a patent date using a Calendar to confirm the patent is on a Tuesday.? If the date is not on a Tuesday there's a typo.

My web pages are filled with patents on all kinds of things including HP instruments.? Here's an old list:


And a general discussion:


I used to visit the Sunnyvale, California patent office and it turns out they are the only one where the patents are filed by Class/Sub-class numbers.? NOT in patent number order.
This allows for easy searching once you know the class numbers for the general area.


If you let me know more specifics I may be able to help.

Re: How to find patents for HP equipment

 

Exactly. I have somewhere (in my storage somewhere) an anniversary book from Kodak Research Labs. It talks about how difficult it was for the labs to communicate with the manufacturing division because they kept everything secret including the changes they made in the research the labs sent. It is rumored that during George Eastman's time only three people in the corporation knew the whole process for making film. At some point, probably in the 1960s the determined that the processes were changing fast enough for patent protection to make sense so started applying for patents although they continued to keep some things secret. If I could find the book I could write more details.

That's one of several ways to run it, yes.

later on they swapped the computer to a HP Vectra but I am not sure if they still used the original basic software or HP actually came out with a DOS version .
They came out with a DOS version, it's called "3048A option 301".

Yes, you can run it from a single volume, like a hard disk or a directory on an SRM server. I run mine via the latter.

In my lab I have an HP9000-382 running HP-UX from a SCSI2SD board, with an SRM card installed in a DIO slot, with the SRM-UX package installed. Over by my 3048A in the other room, I have an HP9000-340 that boots BASIC via SRM. On the SRM server, I have (among many others) a subdirectory called "HP3048A". I change to that directory, load the program, and run it.

I initially copied the files from the floppy disks into the 3048A directory on the SRM server, just piling all of the disks' contents into that directory.

You should be able to do the same thing, by just copying them into a directory on an HP-IB drive. (real or emulated)

Hello,

I asked this question as part of another question on VintHPcom
(/g/VintHPcom/message/7448). However, I believe people
in this group are likely to have familiarity with the 3048A software so
I'm somewhat cross-posting here.

I'm trying to run the HP 3048A software from my HP 382. However, I
believe my floppy drive may be bad. Is there a way to run this software
from program files instead of from floppy disks?

I got the software from hparchive
(). That includes
the disk images and the ASCII files. I can use hpdir/hpdrive to copy the
ASCII files to the hpdrive emulated hard drive. I can then run PHASE
with GET "PHASE". But this then prompts me to input the "PHASE_SUBS"
floppy to proceed. Is there a way to provide the "PHASE_SUBS" ASCII file
instead of the floppy?

I think another way to do this would be to get another GPIB adapter and
emulate a floppy drive with another invocation of hpdrive. But, I'd
prefer to avoid buying another GPIB adapter if I can.

Thanks,
Matt

Have you checked the supply voltage level for the EEPROM ? if the supply voltage is below a certain level than the device is write protected , this is a safety feature that allows designers to use a EEPROM as a replacement for traditional EPROMS

The switch in both cases was not faulty. I think the write protect was activated, but as to the reason, I cannot say for certain. Every other aspect of the analyzer seems to be functional. I also thought it strange that the CPU Board recognizes when S400 SW8 ALT ENABLE is thrown during some of the routines.

?

This one remains a mystery to me.?

That is indeed strange , the only thing I can think of is that the switch is faulty or that somehow the EEPROM has a write protect enabled

Yes I threw S400 SW8 - I was never able to get the load to work. In both CPU¡¯s with License Activation Keys it would report ¡°56 OPT COR FAIL¡± when attempting to load it.?

?

Trust me, if there were a way not to remove the EEPROM¡¯s I would have done it. It was after multiple attempts with two CPU¡¯s with the License Key for each Serial Number I opted to edit the Binaries of the EEPROM.?

Hmmm have you unprotected the EEPROM ?? the E has the new flash based CPU board there is a little switch on the board that you have to toggle to remove the write protect.

I have fixed and upgraded well over 100 8753 and 8720 VNA when I was working at tucker and I don¡¯t recall any instance when the option codes did not work

I did not see any reference to the 8753E Series on Yahoo Groups. ?I did see some reference to the earlier versions to include those provided by Marcus.?

?

With regards to the Option Codes, I did get options code for both CPU¡¯s from Cesar. Both of them would not take these codes. This issue still puzzles me. I could understand a hardware fault for one not taking it, but two makes me thing some of the units were locked down somehow.?

Thanks. That software's great, but unfortunately it's not complete. In
particular it does not allow me to perform the calibration procedure.
