Hi Fred,
Is that an official translation of CNS 13438? By the way in visiting your
website I notice that you stipulate that In-country testing is required for
most equipment Under the APEC Mutual Recognition Arrangement, both Taiwan
and the US being signatories, it is not required that testing

Take a look at multi-layer ceramic capacitors from American Technical
Ceramics. I used to buy 1.5 uF discoidal models (about 5/8 diameter by 1/8
thick) from them. I imagine that they now have rectangular surface-mount
multi-layers capacitors now.

Amund,
There are multiple countries that have Country of Origin (CoC)
marking requirements. Probably all for the same reasons, i.e.
tariffs, truth in advertising, etc. Many countries have their
own lists of countries from whom they will not accept imported
goods, usually for economic and/or
Just to keep the record straight, Kapton is a polyimide, not a
polyamide. They are vastly different. Polyamide is the general name for
the family of polymers commonly referred to as Nylon.

Hello Cecil,
Although it is common practice to extrapolate
test distances using a linear scale (20 dB/dec)
you need to be warned about the theory behind it
that suggest different.
Using an OATS type of measurement , the reflected wave
by the ground plane does at 10 meters distance fully

Yes, it's dBuV/m.

Amund,
Thanks for the info, not having a copy of the standard, may I out of
curiosity ask about the measurement bandwidth for the various bands?
The way I see it, I suppose you have to test Radiated Emission down to 150
kHz which is very unusual because it will bring you into the near field.
The following answer represents my thoughts on the technical aspects - I
don't know if there are any rules/regulations which govern when you can test
at three vs. ten meters. The key issue is that the measurement separation
represent the far field, since the FCC scaling represents far field
