Ari,
Circuit diagram is EN61000-4-5: Figure 10. My coil was 20mH coil:

Hello news group readers,
MANY thanks for your replies on my question.
The general advice was to place the PC outside the anechoic room. And to try to
test with a constant communication for reproducibly.
A second point was that David Sterner has advised a test set-up for the
ethernet in

David,
if you have a decoupling circuit that keeps the surge away but passes
ethernet,
how about posting the details here?
Lots of us would be most interested!

Mike,
A method that surges two units simultaneously (as with coaxial cable) is
good.
Justification:
IEEE 802.3 compliance
A link with a 20mH decoupler is atypical and non-compliant with ANSI/IEEE
802.3 (a.k.a. ISO/IEC 8802-3) Ethernet

Each end individually, or the whole link at once?? Each end by itself is
easier (constrained, of course, by the availability of couplers). I'll pass
your comments along

Richard,
We made our own decoupler with low-resistance 20mH coils.
You really should
have an active link during conditioning. Off-line surge will
not detect

You will not be able to transfer data when the decoupling network is added
for the I/O surge

Hello newsgroup readers,
Question about the EMC test set-up for Emission + Immunity.
We are developing a product which can be connected to the ethernet / LAN/
Internet.
Do we need to connect the product to a PC (with ethernet card) in the anechoic
room or can we decide to place the PC outside
