Does anybody have any experience with EMC testing to IEC 60945 ?
The scope of the standard mentions that EMC requirements apply to ‘all other

There is a lot of work going on at regional level in the Gulf also, and these
2 states are part of that. The Gulf Cooperation Council (GCC) has put in place
a standards org � the GSO � to produce harmormonized standards (based on

From IEC60945 scope:
This standard specifies minimum performance requirements, methods of testing
and required test results for general requirements which can be applied to
those characteristics common to all equipment described hereunder:
c) for EMC only, all other bridge-mounted equipment,
The limit of 24 dBuV QP should be measured with a bandwidth of 9 kHz,
a combination that is not too common (I mean QP and 9 kHz BW)in measuring
receivers but the newest.
Alternately 30 dBuV peak may be applied, and then 9 (10) kHz is a normal
setting.
60945 also requires 1-2 GHz emission
I thought that the default measuring distance was 3 meter, even in the 150kHz
– 30MHz band.

The FCC measuring distance for radiated emissions in that freq range is 300
meters and 30 meters.
As usual, other measuring distances are allowed and corrections made to either
move the limit to the measured distance or move measurement to the limit
distance. There are certain advantages hidden

Hi all,
We are in the process of building an OATS and we have a building/enclosure
that is made of fiberglass. A link to the enclosure link can be seen below. My
question is does the door opening to the dome need to be facing the antenna
mast while tests are running so that there is no
Cody,
Many years ago I did an NSA measurement on an OATS that had a (large
room-size, not tent-size) rectangular fiberglass enclosure over the turntable.
There was a personnel door between the turntable and the antenna. With this
door open, the difference in dielectric constant between the

The changing technology is being dealt with in several ways.
IEC 60825-2 has been developed as safety requirements for LEDs that
are not lasers.
