The point is that RE/CE protect broadcast bands. Making an RE measurement
(E or H field, regardless) from a LAN line a couple meters long is not
representative of what you would measure if the LAN line were significantly
longer, as it might be in situ. Therefore a CE measurement can be better

is where you stress the product (prototype stage typically) using a number
of criteria, the most common being temperature extremes and vibration. You

Subject: 90 V gas-filled arrestors source?
Anyone know where to obtain a draft copy of the new HDSL2
Interoperability standard T1E1.418-2000? I believe the document is
still undergoing final revisions, but a recent draft copy would be a big
help. Thanks...

All,
As Ghery reported before (lost in the recent threads, but copied below), the
closely related issue cf definition creepage is being addressed by CISPR SC G
and is already is CDV stage but not yet FDIS. If it isn't already too late,
this might be the best or only opportunity we'll get for
Hello group,
Does anyone know who makes gas-filled arrestors called for in IEC 1000-4-5
coupling networks? Would a MOV be ok?
Thanks,

I hope you don't live in the UK, the cost of the fuel would make the test
far too expensive to perform$1.22 for a litre of diesel!

Paolo,
You bring up an interesting point about FCC. FCC recognizes CISPR
22:1985 is as an alternative test method. The 1985 version does not
specify emissions on LAN or telco.
FCC Part 68 specifies conducted emissions only on mains cables over
450kHz

Ken, that is not what Mike is saying. Mike's statment was to the effect
that if the noise can get out of the EUT then noise from another source can
get in. A point of exit can also be a point of entry for EMI. This applies
to all types of launching mechanisms, not just cables. Also, just

2) Several outfits make/sell these probes - all isotropic: Narda Microwave East

Hi Ron,
I believe Elliott Labs in Sunnyvale, CA does such testing
and have a very good customer focus.
