Heh, Heh I guess its no coincidence that the EOS/ESD Association has had meetings and symposia at both Vegas and Reno in the past few years. A MiniZap will almost fit in your pocket--you just have to be careful where you're pointing and avoid loose change when you hit the "trigger", but I dig

Jacques: As I understand, the intent is that, yes, ETS 300 386-X will become a suite of harmonized standards but there are no firm dates for implementation. Apparently, ETS 300 386-2-2 was recently voted on and passed and is now awaiting publishing in the OJ. ETS 300 386-1 is the overview docume

Moshe: One possible source of the phenomenon you've observed could likely be "beating" caused by assynchronous clocks. It's even more defined when the frequencies are slightly skewed by an amount slightly less than your receiver bandwidth. Take for example, you have two processors running off t

Hi: I've recently had a need to re-visit the application of EFT pulses on AC power cords. Although the current version of the std. (1st ed.,1995) discusses assymetric application of the EFT pulse (Section 6.2), the std does not explicitly describe that the pulse application must be done on one

You pose a darn good question below, but sorry, I don't have an answer, just more commentary. The 1984 version of IEC 801-2 differs quite significantly from the 1991 version (currently 1000-4-2): - the discharge network is different: 150 ohm/150 pF versus 330 ohm/150 pF - the discharge curren
