SAR requirement in Mexico

I would appreciate if someone could provide info of SAR/MPE requirement in Mexico. I assume they don't have yet any mandatory requirement right now. Thanks Fang This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list. Visit our web site at: ht

A 100 MHz oscilloscope and a Pelligrini target would be good for viewing all but the leading edge. With this one can look for runt pulses, correct current, correct decay time, and missing pulses. The rise time is 3 ns and the cheapest 100 MHz TEK oscilloscope is around $1300. A 500 MHz oscilloscope

Major waste of time -- been through this a number of times with people believing it would be a good idea to convert from time domain to frequency domain when evaluating ESD simulators -- WG14 of the ESD Association did quite a bit of work in this area and in the end, stick with the time domain

Helge, Thank you. That is the exact information that I was looking for. I spent four hours over three days trying to find this information on my own before posting my request to this forum--including two inconclusive rounds of E-mails with the *one* standards vendor that looked like they *might*

I've often wondered... Most people who have an ESD gun have a spectrum analyzer. Most ESD guns have a multiple discharge setting. What if you made a "coupling strip", such as a 12 inch long x 1 inch wide piece of copper tape mounted on a board; then used two 970 Ohm resistors to bond the stri

Gents Whilst neither of the amendments referred to below affect the sort of equipment we produce or test it is "interesting" and not uncommon that there is a delay between the publication of the IEC version and the BS EN version. I have always applied the BS EN version. Am I correct in following
