Thank you, but that page is where the problems I described actually 
happen. I can't successfully download even one article.


It doesn't seem sensible anyway; why not behave like most on-line 
journals?

Re: [PSES] IEEE Electromagnetic Compatibility magazine

[Ravinder Ajmani]

I receive the print version of IEEE Electromagnetic Compatibility Magazine.  
When I saw the email from IEEE, I too thought that I could download the pdf 
version of the magazine.  However as you have stated, I could only get 
individual articles through Xplore because my Company is a subscriber to 
Xplore.  I believe unless you are Xplore subscriber, you may not be able to 
view or download the full articles.

I sent a help request and have received a most bizarre response, indicating

It's so off-beam that I can't even reply to it sensibly.

Re: [PSES] Suitable Transformer for AF E Field Susceptibility Test

AE Techron builds a transformer for sec 19 testing. They rate it up to 3700V. 
Maybe they have one for higher voltage. Here is the link.

Hi

Question for the DO-160 people out there, looking for an alternative High 
Voltage Transformer to run Section 19 testing.

Currently trying a NEON sign transformer but have found the type we have is 
filtered (can you believe it!). If anyone has successfully used one or have a 
tried alternative I'd like to hear what you used :-) 

The frequency response needs to be 380Hz - 15KHz as a minimum but up to 32KHz 
preferred. We're driving it with a TECHRON amp and need to make 5.5KV but very 
little current

Thanks

None of these items, including the control box, are 'placed on the 
market' but they are 'taken into service'. However, IF they do not cross 
any Member State borders, I can't see the authorities even knowing about 
them UNLESS an interference incident occurs. So I suggest you attend to 
the emissions and not be too concerned about formal marking.

[PSES] Applicability of EU CE Marking Directive requirements on "free issue" Development Electrical Hardware

[STEVENSON Philip]

Dear List Members

I am looking your guidance on whether the EU CE Marking Directive requirements 
are applicable or not to "products" build during the development lifecycle for 
its the design verification and qualification testing. These "development 
versions of the "product" will not be put on to the market place but will be 
supplied a partner company in the UK "free of charge" as an assembly for 
integration into the complete system to allow the qualification testing of the 
complete system to be carried out. The development complete system "will also 
not be put on to the marketplace" in the same context that is only to be used 
for design qualification testing purposes.

So my question is, does the supplying "development versions of a "product" to 
another UK company who also are working on the same contract to produce a final 
product for a UK customer outside the scope of the CE Marking directive or not? 
That is does it have to be CE Marked or not?

As part of our design process a safety assessment of "development versions of 
the "product"" is undertaken and the assessment documented. This assessment has 
to done and approved before it can be supplied to the partner company. The 
product being supplied has been assessed for CE Marking and only falls within 
the scope of the EMC Directive.

It is the intention for the production standard version of this  "product" to 
be CE Marked in accordance with the EU CE Marking Directive. That is before it 
is supplied to the customer.

To push my luck a bit further with getting advice from the membership I have a 
secondary question relating to simple "Control Box" that will only be supplied 
and used with "early development versions of a "product"" described above to 
control its operation during initial development testing. The "Control Box" 
consists of a Die-cast box with an input connector, output connector, two 
toggle switches and internal wiring. The "Control Box" simply receives a 24V dc 
input and connects this supply to the product. The Toggle Switches switch the 
24Vdc to control inputs on the product to control its mode of operation. As the 
"Control Box" as no "active" components I believe it can be considered as being 
"EMC Benign" and therefore outside the scope of the EMC directive. Therefore it 
doesn't need to be CE Marked. Does the membership agree with my assessment or 
not?
PS The 24Vdc supply is provided from COTS (CE Marked) Bench DC Power Supply.

All help and guidance will be greatly appreciated.

James,

You'll likely get some other "been there, got the Tee shirt" replies beside 
mine. Could you re-post the comment on one of LinkedIn's EMC 
groups? Would you mind if *I* did?   The ARRL EMC group probably need a 
heads-up, too, and maybe Electronic Design, et al..  Companies have short 
memories.

Back in 1986 or so, my brother's VERY high-resolution B&W monitor was 
interfering with his neighbors television reception on the18th floor of a 
Boston MA building. Considering that the transmitting antenna was a few miles 
away and line-of-sight, it had to have been really, really bad. I was able to 
fix that with an external 360 degree shield over the cable, tightly held to the 
EMC backshells with cable ties.  A few years later, At Tandy Computers, I 
tested a 3rd Party TV tuner card when the video cable provided with it made a 
(formerly) compliant computer fail Part 15 -- and only when the tuner function 
was off; somebody had missed that.  Fun times.

Re: [PSES] HDMI extension cable recommendation?

[Pawson, James]

Hi Brent,

In my experience from sourcing and testing many standard HDMI cables it is very 
difficult to get a good quality shielded cable without working closely with the 
vendors. At the very least a copper foil backshell with good solder termination 
should be specified but better performance can be had with an all metal two 
part backshell.

Most of the products sold through Amazon, eBay, etc. are generally unshielded 
or poorly shielded. I even tested some expensive super Hi-Fi HDMI cables that 
retailed for $30 for 1m and they were just as bad as the rest. Ones with 
moulded "ferrites" on them were often found to perform the worst.

I would try and find parts from a reputable manufacturer, perhaps Molex, 
Amphenol and try them. Be prepared to buy and test several samples before you 
find The One.

I hope this helps,
James

Subject: [PSES] HDMI extension cable recommendation?

I’m looking for a good quality HDMI extension cable for test use.  Price is not 
an issue since I only need a few.  Does anyone have any recommendations based 
on their shielding and build quality?

Thanks!

Of course you weren't. The problem with statements on moral issues is 
that they tend to beget more and more statements on moral issues.
