Muriel,
Coupling/Decoupling networks (of which LISN's are a subgroup) can affect DUT
performance. I myself have not experienced this with a conducted emissions
LISN, but I have experienced it with an EFT generator.
We made a product that had an internal thermal printer. We EFT test in
house.
Muriel, this is a very question, and I'll let better qualified people answer
your specific concerns.
Now, if I may add my 2 cents worth of experience in a 'similar' situation
that involved conducted emission on SIGNAL leads: Under certain conditions,
when the required CDN does interfere with
William,
This is a truly valuable forum!!!
Thanks for your prompt email response. Perhaps the updated version is EC No.
2037/2000.
I was sent a copy of Regulation (EC) No 2037/2000 of the European Parliament
and the Council of 29 June 2000 on substances that deplete the ozone layer

Muriel,
1) Your equipment must be designed to operate from the LISN. It must not
resonate, generate extra ripple, etc. The concept is that EUT sees a low
enough source impedance when connected to any real power distribution system
that it operates in a STABLE mode. That means your input
Hello Group!
First of all, I wish a merry christmas and a happy new year for the list
members.
Second, I'd like to solve a doubt. It concerns the methodology of
conducted emissions tests.
Let's suppose a power electronic equipment (static converter) that has a
boost converter in the entrance
I want to erect a simple, low cost removable canopy over our turntable at
our OATS to protect the EUT from light rain and our Florida sun. Is anyone
aware of an off-the-shelf option? Has anyone constructed a simple canopy and
would like to share their design and/or experience (good and bad)?
Joe,
I believe electric strength, clause 5.3, table 18, operation insulation,
secondary to body or between independent secondaries, 500 V rms. It is my
understanding that he accepted the exemption based on a permanent ground
connection, and that the test is necessary if there is no permanent
Hi
Sorry to disagree but I have been in contact with the Commission and various
governments around Europe including Germany, Sweden, UK. Eire, France etc.
Although there is a common position in that HCFC are to phased out, certain
governments have gone that extra mile and banned HCFC through

reading through this and speaking to the companies environmental adviser, you
have been miss informed. HCFC are the temporary replacement for CFCs, and they

Dear Tin
There is indeed a ban on new equipment entering the EU from 01.01.2001. The
original EU Regulation, which implements the requirements of the Montreal
Protocol, was called EC 3093/94. this has since been replaced with an updated
version but I do not have the reference to hand.
Although

The limits for class A are absolute, independent of the input power to
the equipment. The class D limits are proportional to your input power,
(1st column) up to the maximum permissible harmonic current given in the
second column of the class D table (which is the same as class A)
e.g. A
