Greetings group,
I am trying to draw a parallel between transmission line theory and radiated
emissions.

Why not take the opposite approach, and select the radiating frequencies
from the EUT. Place antennas near the EUT, and select only those frequencies
that are most likely coming from the unit.

Hello Group,
I apologize for this potentially dumb question..
Can I consider a product (very low voltage, Outside the LVD) that has been
tested (and approved) to UL1950, Cls 6 as meeting EN60950, cls 6
requirements ?
What are the significant (requirements) differences between UL1950, Clause 6

I believe IEC 61326 "Electrical equipment for measurement, control & lab

As I understand it EN61326-1, Electrical Equipment for Measurement, Control,

Hi Folks,
Well it is time for me to get a new environmental chamber. I need a unit
with temperature and humidity control and also automated control from a
computer. We are looking for a capacity in the 8 cubic foot range. Does
anyone have some manufacturer names and model numbers for a chamber th

(1) EMC -- What Charles wants is only Immunity requirement. I agree with
you that the Immunity part of EN 61326-1 would suffice.
(2) Safety -- It seems to me that EN 61010-1 "Safety Requirements for

I am not an expert in this area, but I believe that there is an applicable

covers both emissions and immunity requirements, and I kno

To state the obvious first, I know of no EMC standard which refers
specifically to laboratory equipment. However, I would think that
talking to your customers about EMC may result in the most sensible
