Otherwise, call the Italian Embassy in Washington, D.C.

Is it legal to appliances in Italy that have Schuko CEE 7/7 plugs? 

All my Wikipedia research says that this is common. 

Is there a government regulatory body that can answer this? I could not find an 
answer on the mise.gov.it website, or a contact to ask.

Re: [PSES] EMC/EMI Cables - Don't cut yourself

2021-04-29 Thread John E Allen 
"Pretty Similar" story from about 8 yrs ago when working  as a contractor  for 
a UK division of a very large Oil & Gas instrumentation contractor:

The DUT consisted of a surface control & interface  unit and a "downhole" (i.e. 
goes down inside the metal casing of a oil well extraction pipe)  measuring 
unit, and, for testing purposes on the surface, connected by an about 2m long 
cable assembly.

Took it for Class A RE testing at a very local lab, but stopped the test after 
about 20 mins when it was clear that the DUT was "spewing" RF "everywhere" 
across the spectrum

I immediately had a pretty good idea where the problem lay because everything 
but the connecting cable was pretty much solidly metal-cased - thus the cable 
was the prime suspect.

Back in the lab, I disassembled the cable = 2 lengths of reasonably well 
shielded cable -  but joined in the middle by a small electronic interface unit 
in a plastic box with only a very thin stranded conductor between the screens 
of the two cables! (The original designers were generally very good and clued 
up, but had little concept of EMC design  & control!).

Long story cut short: replaced the plastic box with a metal one with 360 deg 
shielded metal cable glands at each end, and introduced 360 deg  shielding on 
the cable connecters to the control unit and the downhole measuring unit -> 
result = passed Class with a reasonable margin, but it cost the company well 
over £300 to replace the cables in each of the 200+ kits that they had already 
shipped, AND a lot of time & effort to do that!

"Simple" good EMC design practice much earlier on would have saved that company 
a LOT of heartache & cash!

Story.

This happened 20+ years ago so don't shoot me.

An outside vendor was supplying the Operator Interface Console for our new 
Ultrasound machine. This console was a slick EMC design, each of the 11 or more 
rotary encoders that used low power CPU's that went to sleep after rotation. I 
was told the PIC chips were parasitic powered to reduce EMC. Wow, nice 
considering diagnostic Ultrasound was essentially a multi channel sub-microvolt 
receiver with a piezoelectric transducer as the patient antenna.

The new machine was failing RE on the 10m OATS and the operator interface 
console EMC Engineer came to visit us to see why.
"How good are your 360 degree shielded connectors?" "We don't know."
The EMC Engineer then looks at us and says some to the effect, "Oh goody, this 
is the part I like the most." He whips out his pocket knife and starts pealing 
off the hard plastic over-molded connector...
The project engineer and myself looks at each other with our mouths hanging 
open while the connector was being dissected - and then the EMC guy cuts 
himself. I felt bad for him, he was a "sharp" EMC engineer and he did find the 
problem.

Moral to this story - Don't cut yourself!

Re: [PSES] EMC/EMI Cables

2021-04-29 Thread Chester Summers 
Hi, Cass—

If your company’s PCB inspection team uses x-ray equipment ask if they will 
take a few pictures for you.  Dissecting suspect cables is certainly valuable 
and often essential, but you can also learn quite a lot about which shielded 
cables are “good” or “bad”, not really shielded at all, twisted/terminated well 
or not, etc via x-ray.  Not all expensive brand name cables stack up, and the 
internal construction of what you purchased last year may have changed 
considerably without any outward indications.

Good luck,
Chet

Any cable labeled as 2.1-compliant should still be dissected.

Subject: [PSES] EMC/EMI Cables

Hi guys,

I am having issues with getting audio/video product to pass the class A limit. 
I've narrowed it down to the HDMI cables. Even the ones with the ferrites on 
both ends are inconsistent.

Does anyone have a recommendation on where to find good EMI/EMC HDMI Cables.

Thanks,

Cass

I haven’t dissected an HDMI cable in a couple of years, but the HDMI
Adopters consortium calls out lower EMI for 2.1-compliant cables:

https://www.hdmi.org/spec21sub/ultrahighspeedcable

Any cable labeled as 2.1-compliant should still be dissected.

There is a company called Sewelldirect that used to provide a well shielded 
HDMI cable. They had a webpage on the subject. However, I can't find it on 
their website anymore.

Apple sell a properly shielded HDMI cable.

The only sure way to qualify an HDMI cable manufacturer is to dissect the 
connector - cable termination and check for pigtails.

The article references some original investigations by Begey and Altland 
(DesignCon 2008).
