RE: Common Mode or Differential Mode

Radiation is always (99.999%) due to CM. Conducted can be either; use LISN Mate or a Current probe. Mark -Original Message- From: rehel...@mmm.com [mailto:rehel...@mmm.com] Sent: Tuesday, January 04, 2000 2:20 AM To: emc-p...@majordomo.ieee.org Subject: Common Mode or Differential Mode

RE: CISPR 22 equal to EN55022?

I'm hardly the EMC attorney, but I believe the way it works is the technical body generates CISPR 22, and the lawyers adopt and publish it as EN55022 Mark -Original Message- From: Matejic, Mirko [mailto:mmate...@foxboro.com] Sent: Thursday, July 08, 1999 2:34 PM To: 'Richard Cass';

Radiation from transmission lines

To add another $0.02 worth... There are two mechanisms for radiation: transmission line fields, and ground noise. The fringing fields from the trace determine the radiation. Therefore, the height of the trace above the gnd plane (coupling) determines the radiation by this mechanism. The
