Conducted Emission testing for Ethernet over power line product.

Hi Group, I am looking for an opinion regarding an interpretation and implementation of CISPR I/89/CD. Let's say you have a product that can transmit Ethernet over power lines in your house (this is not power over Ethernet). This could be considered as Power Line Communication with Multi Purpose

Re: Are there any knowm EMC porblems when transmitting video on gigabite ethernet?

It is just Ethernet traffic, so there should be no difference in emission. Immunity might be a problem, since during some tests (e.g. EFT), temporary loss of packets and link-drop will most likely happen. That is not an issue with regular data-only Ethernet applications, since Ethernet

Are there any knowm EMC porblems when transmitting video on gigabite ethernet?

Hi everyone Does any member know of any known EMC problems associated with transmitting video over a gigabite ethernet system? Regards Andy ___ Andrew Price Principal Hardware Engineer (EMC Specialist) SELEX Sensors and Airborne Systems Christopher

This is a multi-part message in MIME format. Isn't it fun, that's why I am not sure if being called an EMC expert is a good thing. Now to the point: 1) Pulling back the Vcc plane away from the edge of the ground plane changes the distribution of the EM field at the edge. While the strength

RE: WEEE labelling in the UK

So what are you doing about product you are selling in MS who already have legislation? Historic waste is everything pre 13 Aug 2005 - you can't have different dates throughout the MS. If you apply the wheelie without the bar but have the date marked on the unit you cover all bases. Bottom line

Re: Suppression of radiated emissions and spread spectrum clocking

Thank you, now that I understand that 20 H means the power plane outside edge is set back from the ground plane edge a distance 20 times the separation between the two planes, it is possible to opine on the subject. Looking at the fringing field set up by potentials and gradients between the two
