I don't believe Ed was wrong at all, in most any case I can think of he was
precisely correct. Whether you use 10 log () or 20 log () depends upon
whether the ratio that is the argument of the log function is power or
something related to power by a square-law relationship. The most obvious

Thanks Nick,
I knew that what was happening with the CB wasn't right, but I was afraid to
challenge them since they would presumably know more than me, and therefore
in some way may have been able to justify what they were (are) doing.
As for the EN60439 issue, I have found that certain labs will
Peter,
The answer should be yes. EN 61558 is included in the normative
references list of EN60335 as amended by AMD 13050 of August 2001.
Regards
Nick.

John,
I agree with your statements as I've correlated EN standards to satisfy a
customer who wanted S2 compliance.
I believe our last statements in our email sums it all up.
"You may want to get a copy of SEMI S2 and identify the delta's between S2
and your EN certifications to your customers."
Can anyone tell me which Directive the following standard falls under (is
harmonized to):
EN 12895 Industrial Trucks - Electromagnetic Compatibility

Hello Listmembers:
A recent thread was discussing the effects of RF emission on plant life in a
rural environment. I finally managed to remember that the US Navy had become
embroiled in this same environmental question when they attempted to
construct a huge ELF antenna system in Michigan and Wi
I proposed the capacitance unit of dBF with tongue firmly planted in cheek.
And yes, maybe 10 Log is more proper than 20 Log (hey, 44.5 dB error is as
close as I get sometimes).
OTOH, the more I think about it, resistance, inductance and capacitance
values in practical circuitry exist over such a
Hi all
I have just got a PMM 8010 and 8030 but without software, I can only
download a WIN update from PMM not the whole software. Can some one help
me with a copy of the original software ?
Best regards,

Hi
Just to clarify that SEMI S2 although primariliy being driven in the US is used
worldwide within the Smiconductor industry with more European customers
expecting the product to meet the requirements of the relevant SEMI documents.

Dear All,
It has been a long time since someone raised an EN 60335/IEC 60335 issue! I
am honored to be the person.
Can a plug-in power supply evaluated to EN61558-1 and EN61557-2-6 be used
without further investigation in a EN60335-1 type product?

Dear all,
I wonder if dBF is 20 log C or 10 log C ?
My personal guess is that if VA= V² Z and Z=sC then I suppose dBF should
carry a 10 log tag. Could Ed be 44.5 dB off the mark?
