Hello all,I have written a short introductory article on reverberation chambers
for a local EMC magazine here in Australia.This is enclosed for anybody who has
similar interests.Thanks

Your could try to come and visit us at our lab in St Marys, NSW while we
test a lot of commercial and military stuff, apart from development work on
reverberation chambers. Unfortunately, we cannot release procedures as they
are proprietary.

, MIL STD 461D and most commercial standards
have got around this NB/BB emission discrimination mess by specifying the
measurement BW.
Hope this helps.

A zoomed in measurement from 3m to 1m to beat the noise floor is not
recommended as the antenna and EUT dimensions become critical.

ese are the types of jobs where one forgets about the use of LISNs and
shudders at the thought of using a HV probe.
Cost of such stringent EMC testing will almost inevitably be built into the
contract.

#x27;s friend for MIL STD 461/462 CS06 (in air!!), or
CS115/CS116/ RS02 pre compliance.
I cannot comment on your Fire Alarm system though, but I would hazard a
guess and attribute it to HCP or capacitive coupling via unshielded cables
spaced off the metal test sheet (the GRP).

other immunity standards we start off gradually till we reach the
stated limit values, which is the way I believe it should be done. But it
increases the time, especially for Surge tests where you got to hit at
different points on the sine wave quadrant too.

Who knows, we could be using the site verification measurements in Dead Sea

Hi all,
Could someone guide me on where to down load from the net or purchase the
latest version of MIL-HDBK-217 and approximately how much it would cost. It
is a Reliability/MTBF related issue.
Thanks in advance.

And really, at the end of the day, just because the site attenuation of any
site is accurate, this does not mean that the measurement uncertainity has
come down or that the EMC tests that are carried out on the site are equally
accurate (nothing to do with the lab or personnel!!)
