Dave,

I don't want a private discussion off list about this.

Feel free to start another thread about it if you wish. As you say, it

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
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.

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

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

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!

Does any one have a copy of the Users Manual for this Plotter? I have found the Interface Manual on line but not the User Manual.
I may get one to use with my "new" 8559A just for a test/fun.

I even found a place with new pens so may not have to refil them ! ! :-)

Hi Jerry,

The DesignSpark support is only via email and is really only for software issues.

Direct help is mostly in the user group forum.



Try looking for other sources like SparkFun, they have an interesting set of items for DS.

Things like switches are so variable that one often has to make up ones own footprints and symbols.

DS has a different way of putting thing together in the library than you might be used to from other packages. It certainly gave me a headache as I am conditioned from many decades of using what is now Mentor PADS and DxDesigner.

Be warned, the current version of DS does not have net list locking so it is easy to lose nets when routing from inadvertent deletion.

So I would say that DS is okay for small projects, but has the potential to be a complete nightmare if one has big BGAs etc. (imagine losing a net into a 1000+ pad BGA for example).

Also does NOT support partial and buried vias.

But for "Free" and serious it is good start in electronics design with integrated schematic capture and PCB layout. Very suitable for students and hobbiest, but I could not recommend it for any other than basic commercial work (e.g. designing Arduino boards, shields, capes and such stuff).

Personally I use Mentor PADS ES suite (with DxDesigner rather than Logic). It is only "Free" in the sense that it preserves my sanity, still has a high $ cost to buy and maintain.

Best wishes,
Susan.

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.

Hi Cslim,
Thanks, I sure hope you get your generator working correctly.

Hi Jeff,
May have to wait till March 2013. That is the date when Agilent does not
service the HP8648 signal generator anymore. Some boards may appear
somewhere.

You can buy a service manual with schematic but you need to ask that the
seller confirms that the schematic is there - big companies who use lots of
HP8648s with their own service departments have access to service manuals
with schematics.

The other way is to collect specs sheets of all ICs used in the signal
generator and spend time to reverse engineer the memory circuits. Will need
some effort. And needs logic analyzer.

I face the same issue with my HP8648B comms problem. Let's wait till we
have the schematic.

Many SAs that I know of change operating modes somewhere in their span range, from the LO being fully and continuously synthesized, to using open-loop linear sweep tuning. Once the span is large enough, there's no need for precise frequency control, since you couldn't resolve it on screen anyway.

The 500 kHz point is probably where this happens on the 3585A, so look for what things happen internally at this mode change.
