Dear Members,
A side-by-side comparison table between the second and the third edition of
IEC 61000-4-3 has been completed. Thank you very much to those who have
helped.
If you are interested in a copy, please let me know.
Best regards,

Kevin,
You are _not_ violating the standard when you move one meter closer than
three meters. The _minimum_ distance is defined in the standard as one
meter from the tip of a log-periodic array or the center

Hi Kevin
Antennas that have a significant length, and construction, such as a wide
band Bilog made by Schaffner/Chase, are marked where their centers are and
that is where all range distances should be measured from! It is my
understanding that this phase center is a compromise as it moves for

The calibrated uniform field is a 1.5m square vertical plane 0.8m above

Hello Michael,
Is it possible you are confusing the chamber manufacturer's spec for a
volume that will comply with NSA requirements with the plane that will meet
the uniform field spec? When we were seeking bids for a compact chamber for
immunity testing, some of the quotes also indicated
The calibrated uniform field is a 1.5m square vertical plane 0.8m above your
ground plane and 3m from your antenna, usually the tip (the size of the
vertical plane and the antenna distance can be smaller but that's not the
issue here). The EUT is placed so that the panel you are testing is
I don't know how you could get a uniform field one meter deep three meters
from a transmit antenna. The only way I know to get a deep field for
testing purposes is using a parallel plate, and that has bandwidth and
polarization limitations. My understanding of the 1000-4-3 calibration is
that
