Re: Interaction between LISN and EUT

What do you mean by interaction? The LISN functions as a source or load impedance, depending on how you view noise current flow. To what other interaction do you refer? From: Derek Walton lfresea...@aol.com Organization: L F Research Reply-To: lfresea...@aol.com List-Post:

RE: Interaction between LISN and EUT

Hi Derek, You can find information on this, as well as the effects of power supply filter configurations on LISN measurements in chapter 9 of Clayton Paul's book an Introduction to Electromagnetic Compatibility. The ISBN number for this book is 0-471-54927-4. Wayne Cooke Hardware Engineer,

Interaction between LISN and EUT

As I recall from the days of my youth in the Military, we had a simple system that allowed us to have three phones on two wires. Each end had a center-tapped transformer with the center tap being connected to Earth ground. The three conversations were carried line 1 - line 2, line 1 -

RE: China RoHS - EFUP number

Chris, It is probably more important that your number falls somewhere near the average of what other similar products state, that way you don't stick out which could expose you to further scrutiny. Too bad the appendix isn't completely filled out with the suggested or average use periods by

China RoHS - EFUP number

It would seem the final version of the “General Rule of EFUP for EIP” will provide some indicative figures to use for various types of EIP. However for now we are left with the draft guide available here: http://www..rohs-international.com/fi es//General_rule_of_Environment_Friendl

RE: Outside the realm of standards

Thanks for all contributions. I think the result of what you are saying is that the analysis should only consider the product and a single individual. If the risk to an individual is substantially low, then the product is safe. Thanks to John for his observation that religious history shows
