Spare Change

The Coins-in-a-bag thread has been moving from anecdote to anecdote for the past week or so. Let's take this to the next level---sloppy field testing! This morning, I procured two fresh, new 1 gallon size Baggies brand plastic food storage bags, a single Baggies brand sandwich storage bag, and

Re: conductive part definitions

Peter, Here's my two cents ... Extraneous/non-electrical Conductive Part - 1 A conductive part that is not intended to be part of ANY electrical circuit (power or otherwise) of a device. 2. If removed from the device, does not cause any degradation of electrical performa

Re[2]: R&TTE Directive

Hi John et al, You email has raised some questions regarding this new directive. With the introduction of the R&TTE directive (99/5/EC), how does it interplay with the "TTE & Satellite Earth Station Equipment" directive (98/13/EC)? Are they exclusionary? Does one supercede the other? Can

RE: US & Argentina, EMC & Safety Requiremnts

Ian, IRAM, the safety agency in Argentina will accept test reports based upon IEC standards from most any laboratory until 18 June 1999. After that date, you must obtain a Type Certificate from IRAM, and after 18 June 2000, marking is required. Under an MOU, IRAM will accept UL testing to IEC based

Re: explanation of ESD events with coins in baggie.

Ok. Not as complex as I thought-in the TV! It sounds like "simple" RF interference through the antenna. However, I have just tried shaking the "coins in a baggie" at my computer monitor - nothing! Now at a 24 year old TV on wire antennas in my basement. I got nothing at VHF frequencies (54MHz to 21

RE: Leakage Current Measurements

Interesting. During an audit of the facilities of a former employer, the auditor specifically requested that we didn't use the Simpson 228 for EN60950 because of the roll-off of the analog movement above 100Hz. The suggested fix was to build the network as described in the standard, with a hi

Re: explanation of ESD events with coins in baggie.

It was 20 years ago, and now I live in a house without central heating and cable TV , so I can not reproduct that effect. But I remember for sure that the distortion similar to that which you get from spark plugs of internal combustion engines, about half a TV scan line long and repeating itself
