Re: Ownership of 3rd party Agilent Scans

 

The US did not sign on to the Bern Convention until March 1st, 1989. So, if the manual predates this, and copyright was not asserted properly as required by US law at the time, it is effectively in the public domain.?

I don't know about the USA, but here in the UK, you do get copyright,
without actually writing a copyright notice. However, it is suggested
that it is better to add a notice, but it is not actually required.

This point reminds me of when I was a school. Myself and a fellow
classmate got in trouble for something, and as a punishment the head
told us to copy some lines from a book he picked off the shelf. I
don't recall the number of lines, pages etc but he gave us both a pen,
some paper, and we were supposed to copy it. He then went away, while
we were supposed to do this.

My school friend, (who unfortunately died of a heart attack at just
19), noticed there was a copyright notice in the book. So we deceided
it was illegal to copy the writing from the book, se we just say
there, and waited for the teacher to come back. When he came back, and
asked to see what we had written, so we showed him the blank pages.
When he asked why we had not done it, we said because of the copyright
notice!

At this point he picked an old book off the shelf, which had no
copyright notice. I think we copied some of that, though we had a bit
of fun out of it all.

Thanks for posting this. I had not thought of many of your points.

On the other hand some manuals do have a copyright notice. There seems no rhyme or reason as to which do and which don't. Probably just the whim of the technical writer at the time.

Since most are out of print or obsolete the US copyright law does allow copying. Some restrictions may apply.

I do see the point on you being able to copyright your value added work. I'm glad you can do that since it helps to keep documentation for this equipment available.

Fortunately for me I have been able to acquire the original documents for almost all of my HP acquired equipment so I haven't really had to stress too much about it.

The bad ground theory that Vlad just put forward is much overlooked in
this situation . Loosening and re-tightening the screws that hold the
motherboard to the chassis is actually very prudent thing to do with
gear this old. Ground loops and oscillations due to poor grounds in RF
gear are a design engineers nightmare in the beginning and a blind spot
for repair guys after 30+ years in service

Good Luck Dave

In the meantime, one thing you could do is to check if a board edge
connector somewhere in the analyzer is getting oxidation on it. For
boards that plug into the motherboard, this involves pulling them out,
looking at edge connector fingers and the matching part on the
motherboard and putting them back in. However, be careful with the

Re: Ownership of 3rd party Agilent Scans

 

Artek creates something called a "derivative work." And it is quite copyrightable in most countries. As long as Artek defends the intellectual property of their works they are proprietary. Several years ago there were lots of heathkits manuals on bama for free. They were free for many years. Then someone bought the heathkit assets and requested that bama take the manuals off. If bama had any interest in pursuing this legally, they would argue that the previous owners of the intellectual property made no effort to keep them proprietary and allowed the public to circulate them freely (whether allowed intentionally or unintentionally). They would probably have a hard time fighting to get their rights back. Of course, no one wins when things are litigating but the lawyers. But anyway I digress. Artek and other licensed manual vendors do have a derivative work and are protected as such, whether we like it or not :) (BTW: I like it!)

I just finished rewiring my power supply and transformer area. It now looks pretty much like Chris's power supply area does. I'm also leaving the 120 volt heater disconnected after what Bill Ezell told me about those some times shorting out. This one heats up and stabilizes in about 20 min. without the AC heater going. Why HP would run 120 volts through a precision oscillator leaves me scratching my head.

Ownership of 3rd party Agilent Scans

Artekmedia
 

David Kirby

While I abhor this type of posting on a technical forum , per YOUR
request I will make this one public response to your request for a
public "hearing"

Here are the finer points in response to your query

1) We (like you) are licensed by Agilent to make copies "for profit" of
any manual for any product of theirs which is "no longer under support".
We are infact listed as a source of obsolete manuals by Agilent on their
WEB site !

2) Agilent acknowledges that the "value added" by
ArtekMedia/ArtekManuals in doing the 600dpi scans of schematics, adding
bookmarks, OCR, electronic page numbering which match the original page
numbers etc. are the property of ArtekManuals. If you sent the Agilent a
copy of one of our scans and asked them to post it as part of their
archives for free distribution they would decline once they recognized
that it was an ArtekMedia/ArtekManuals scan. They will and have taken
down scans that "slipped through". Note that in the past on two
occasions Agilent purchased ( for non trivial amounts of $$ ) the "full
rights" to a couple of our scans to post on their WEB site acknowledging
the fact that the posting of those scans would kill ( and it did ) the
revenue stream from our work product. What Artekmanuals "owns" is the
value of the reproduction process and it is no different than a musician
doing a "cover" of another musicians work ( for which royalties are
typically paid) for commercial gain.

3) You are perfectly within your rights to redistribute ( within the
confines of your agreement with Agilent) scans that you do of their
manuals to whomever you wish

4) Most of the major sellers of PDF copies on Evil-Bay do have licenses
from Agilent to do so. My observation is that every couple of years the
Agilent legal beagals go through Evil Bay and clean house sending out
decease and desist letters and Evil_Bay removes their listings.
Q-Service, AA4DF (when he was still alive) and MicroManuals for example
are/were all licensed. This last guy ( MicroManuals) by the way, mostly
just retreads free downloads ,if you see he has something listed likely
you can find it for free on the web somewhere.

5) The other free download sites such as BAMA and KO4BB all respect our
scans as well. They will not knowingly post an Artek scan.

6) These folks as well as others know that the amount of time that goes
into producing quality scans is not trivial and that the value we
provide to the larger community needs to be encouraged and protected so
I stay motivated in providing the service. If every scan I did showed
up on a public forum somewhere a few weeks after scanning what would be
the point. What you may also not know is this unlike your scanning
endeavor, ours is not a "hobby". This is a full time 6-10 hours /day,
362 days/year business for almost the last 10 years. We depend on every
dime to pay the mortgage, utilities and most importantly to provide
medical care for my wife of 45 years who is terminally ill with ALS ( I
am not asking for sympathy here just stating facts) , so every penny is
precious. If all our scans were posted for free on the internet I would
stop scanning tomorrow and go become a Walmart greeter or a USPS employee.

I will make no further comments on this subject and to the techno-files
for which this forum was intended my apologies for the bandwidth

I know that "most" of the users of this forum and our scans understand
and respect the work we do. I get enough thank you comments every week.
Can we please now get back to discussing troubleshooting 8566B's and
105C's . If you want argue a point or show support please do not take
up further bandwidth on this forum, a private email to
manuals@artekManuals will suffice.

If anyone would like to purchase ArtekManuals we are getting to the
point where a serious offer would be entertained. As they say in Texas

Vladan,

I uncoupled the bandwidths from the span. When the RBW is 3KHz or greater I see clear spikes. At lower RBWs it isn't really clear if there are spikes, but if there, they are much much smaller. The VBW does not seem to be a player.

Hi Gordon,

When you change the span, other things in the analyzer change too. The resolution bandwidth and video bandwidth probably change at the 500kHz span setting as well. That means you can do another experiment:

Set the span to 500 kHz so you can see the spikes and then defeat the automatic coupling for the IF resolution bandwidth. Step the resolution bandwidth up and down and see if the spikes change as a function of res. bw. alone. Repeat for the video bandwidths.

Vladan

--- In hp_agilent_equipment@..., "pianovt" wrote:

Hi Gordon,

This is almost certainly related to the way the LO is structured. Generally speaking, the LO has to make some changes as the span increases. In your case, for spans that are 500 kHz and larger, the LO uses a different method of generating the signal. I will look at the manual, but this may not be the easiest way to find a bad part, especially since you see the problem (to a lesser extent) in narrower spans as well.

Thanks for the answers. I tried Kicad and like it but it won't led me edit an existing symbol for some reason. The is an icon for it but it does not lite up and I cannot get it to activate. I seem to be making fair progress with designspark but it is one of those locked in to a pcb vendor things,

I will look at Kicad some more and try to find while I cannot edit a symbol. I need to get a 3pdt symbol. No pcb is planned for this project, adding FETs to my curve tracer adapters.

You raise an interesting question.

I once borrowed a manual on the HP 5370B time interval counter from
Poul-Henning Kamp, since I wanted one and at the time there was not
one on the Agilent web site. Having borrowed the manual for nothing, I
thought it was right I offered others the PDF of the manual.

Before distributing that PDF, I asked Agilent for permission. I was
granted a license to do this. I don't recall the exact license
conditions, but I know there was nothing there which prevented me
doing this commerically, or doing more than just that one manual. The
license was free.

So unless I am mistaken, there is no money payable to Agilent for the
right to distribute copies of manuals. One just needs to request a
license, and they give you one. At least that was my experience.

Give you don't own the copyright (Agilent do), and Agilent will let

Give you don't own the copyright (Agilent do), and Agilent will let
others distribute copies of the manuals, I find it hard for you to
argue that it is illegal to distribute a copy of a manual you have
made.

I would add, I have no intent to distriubute manuals commercially, but
if I did want to, I do have a license, although I can't recall the
exact conditions of that license.

I wonder what percentage of selllers on eBay selling CD copies of
manuals actually have a license to do so? I suspect that percentage is
fairly low.

You raise an interesting question.

I once borrowed a manual on the HP 5370B time interval counter from
Poul-Henning Kamp, since I wanted one and at the time there was not
one on the Agilent web site. Having borrowed the manual for nothing, I
thought it was right I offered others the PDF of the manual.

Before distributing that PDF, I asked Agilent for permission. I was
granted a license to do this. I don't recall the exact license
conditions, but I know there was nothing there which prevented me
doing this commerically, or doing more than just that one manual. The
license was free.

So unless I am mistaken, there is no money payable to Agilent for the
right to distribute copies of manuals. One just needs to request a
license, and they give you one. At least that was my experience.

Give you don't own the copyright (Agilent do), and Agilent will let

This not free - about $75, but it is very good.



Great email support

Hi,

Sorry for the wide search but I want to find someone to help get me started with Designspark. a free pcb design package. I have not been able to find a connection to their support. Right now I cannot find switches like 3pdt in their library. I also need advice on changing text size in their symbol creation utility.
Don't use it.

What free stuff do most use? Sorry again.

Eagle, for small stuff, hobby license for large stuff, non-profit is
guaranteed.

Some like it, some hate it.

Re: 8563E +28V shutdown/oscillates

 

IF it takes seconds to cycle on and off, suspect that it's overheating and
protecting itself. The junction temp would be in the 150-160C range, so the
IC would be really, really hot.

From your last post it sounds like the input voltage is what's dropping out?
That'll do it, too!

Good luck -

Re: designspark

 

Hi Jerry,

For work, I use Altium, Viewdraw (now Mentor PADS) and OrCad. Each has its
own features & quirks.

For play I use Express PCB (find it great for even just documenting small
hand-wired stuff) and gEDA gSchem and PCB. The latter is Linux based and is
supported by a big open-source community. A friend of mine uses it
exclusively for his small company.

See:



There is also KiCad, which is free & open source as well. Have not tried
it, but looks pretty nice:




David Jones did a review of it on his EEVblog:




Hope this helps.

/John

I use DIPTRACE, a free version is available which is quite powerful.
I decided on this package on recommendation of a colleague who has much
experience and has tried almost everything available.

Diptrace has a bit of a learning curve and the Library setup can be
challenging. However once you are into it (5 hours) and have gone through
the Tutorial it is easy to use and very powerful.

I was using ExpressPCB which was very easy to use but will not make files
to send to 'other' PCB fabricators, they want you to use their plant.
Before this I used Tango but it was so good it was bought out by a biggie
and discontinued. It was not free but was affordable.

I built a Zen CNC machine and needed Gerber files to drive it, which
Diptrace makes.

There is a Diptrace Forum and many libraries to share.

The program will autoroute and check your PCB against the schematic.
Although I have never used autorouting in the past 40 years I am now
getting into it. My boards have never been very complicated and using PICs
there is seldom more than a dozen components so it has been faster to avoid
autorouting. I have made one board by manually placing key components, then
autorouting and the result was excellent. Learning curve!
Peter.
