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.?

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.

Re: Failing 3585A Spectrum Analyzer
Gordon & Vladen
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

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!) 73 Eugene W2HX From: hp_agilent_equipment@...

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
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 though ..."If you cant run with the big dogs ...stay on the porch"

Re: Failing 3585A Spectrum Analyzer
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.

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.

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.

Hi,
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.

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 -

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 On Sat, Jan 12, 2013 at 11:31 AM, Peter Bunge <bunge@...> wrote: **
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.
