Tim:
Your receiver frequency is very close to the third harmonic of your
transmitter frequency. Perhaps the reflection off the adjacent car reinforced
that harmonic to just exceed the rejection characteristics of the receiver.
You might test that with a different (reflecting) car (with the same

Are they harmonized? Yes, if they have been published by CENELEC. Are they
referenced in the Journal? No (and they won't be). So, the only basic
standards that your product must meet are those that are referenced in
generic, product, or family standards that have been referenced in the
Journal.
Are basic EMC standards harmonized? I have yet to see a basic EMC standard
show up in the OJ. The 61000-4 series are widely used but are not in the OJ.
What gives?

I recently read an article in Conformity discussing Poland's B mark for
safety certification. Could anyone in this group provide more information on
both the EMC and safety requirements for shipping ITE into Poland?
Thanks in advance.

Hello,
I am looking for a finite element analysis package for EMC/EMI
simulation. Would you please email me or the EMC-pstc list the
package you are using?
Thank you very much!

A new discussion has started in Europe about redesigning the EMC

1998-03-06, it's section 36.202.5.
It says the test method in IEC61000-4-11 shall apply with
