Dwight,
I do not know of any online source for Calcavecchio's article. A lot of
engineering-college libraries have the IEEE International Symposium on
Electromagnetic Compatibility Symposium Proceedings in their collections.
The surest source is a 4-CDROM set from the IEEE:
40 Years of IEEE EMC Society Symposia Records
1955 to 1995
Available on CD-ROM!
If you are an IEEE member this set is only $40 plus shipping, see
http://www.ewh.ieee.org/soc/emcs/news9.html
If you are not an IEEE member the set is $200 plus shipping.
The search engine for these CDROM's is rather cranky and limited, only seeming
to have access to publication, author, title, and abstract information. If you
only have one CDROM drive in your computer, it can also drive you batty swapping
the CDROM's in and out... Papers can be readily viewed from the search engine.
Note: you have to go to the taskbar and click on the "next page" icon to get
past the first page. Printing the papers is even tougher. I tried installing
the search engine on my work computer, two of my home computers with CDROM
drives, and on a friend's computer, all running Windows 95/98 and attached to
laser printers. I could not get any of these systems to print directly from the
search engine. I finally wound up retrieving papers as .TIF files, then opening
them in Imaging for Windows (Start > Programs > Accessories > Imaging )
to print them out.
But if you are willing to put up with these "quirks", this CDROM set is an
absolute goldmine of information on electromagnetic compatibility (EMC) and
related topics.
I now have over 1200 books, reports, articles, and papers on designing
electronic equipment for ESD-immunity, collected in preparation for writing an
article for Printed Circuit Design magazine (and maybe a book, afterwards...)
The only other references that I recall having on the IBM Tabletop ESD Tests are
classified IBM Internal Use Only, inherited from when we were still a part of
IBM. I've seen a couple of references to IBM Technical Reports, but they seem
to be classified at least IBM Confidential, and not even our own EMC Lab folks
have them or can get them. I will be going through my entire collection over
the next few weeks while writing the article. So, if I find any other
references to crossed-vane ESD tests/testers, I will post them to this forum.

John-
I looked through the IEEE website, but didn't find the 1986 article. Do you
know of an online source for that document? thanks
Dwight

Subject: Re: Product Robustness -- ESD
Don,
We use an IBM crossed-vane Electrostatic Discharge (ESD) simulator to test
110V
and 110/220V products, and an IEC 61000-4-2 ESD simulator to test 220V and
110/220V products. The IEC 61000-4-2 tester works very well finding direct-
discharge ESD problems. For indirect-discharge ESD, such as furniture ESD,
the
crossed-vane simulator seems to be much harsher than the IEC 61000-4-2
Horizontal Coupling Plane (HCP) and Vertical Coupling Plane (VCP) tests.
Part
of this is statistical:
* Zapping the product at up to 60Hz versus once every 2-5 seconds.
* Zapping the product with 10's of 1000's of zaps versus a few hundred zaps
in
a test session.
The crossed-vane ESD simulator really excels at finding cabling problems and
shielding problems that make the product susceptible to magnetic-field
pickup.
For a readily-available description of the IBM Tabletop ESD Test, see
Calcavecchio, Ralph J., and Pratt, Daniel J.,
"A Standard Test to Determine the Susceptibility of a Machine to
Electrostatic
Discharge," 1986 IEEE International
Symposium on Electromagnetic Compatibility Symposium Record, San Diego, CA,
Sept. 16-18, 1986, pp. 475-482.
