Jim and group,
The British Standards version of EN 55022:2006 does not have a section 6.2 and
only covers radiated emissions 30 - 1000 MHz. I also have a version obtained
>from Dansk Standards that consisted of a list of modifications to CISPR 22
that was attached to CISPR 22 Edition 5.2 (Edition 5:2005 consolidated with
amendments 1:2005 and 2:2006.
It is my understanding that EN 55022:2006 is a modified version of CISPR
22:2005 without its amendments (the Official Journal listing shows EN
55022:2006 as CISPR 22:2005 (Modified)). As it is the amendments that contain
the requirements for radiated emissions above 1GHz, EN 55022:2006 does not go
above 1GHz.
So, my understanding, is that the significant differences between EN
55022:1998 with amendments A1 and A2 and EN 55022:2006 are the removal of the
need for ferrite clamps on cables exiting the test site and the modifications
to the ISN requirements for measuring the conducted emissions on
telecommunications ports.
Regards,
Mark

EN 55022:2006 does indeed include the limits for radiated emissions in
the
range 1 GHz to 6 GHz. Look at section 6.2. This standard is published in
the OJ and becomes compulsory under the EMC Directive as of 1 Oct 2009.

Subject: Radiated Emission Measurements above 1GHz
We have copies of AS/NZS CISPR 22:2006 and CNS 13438:2006, both of
which show
radiated emission limits in the range 1-6GHz. Both reference CISPR 16-1-4 for
the description of the test site. (Our copy of EN55022:2006 does not show any
such limits.)
A few questions:
Has the CISPR test site for > 1GHz been decided?
Has the validation method for the site been decided?
If the test site or site validation method is still not settled, how
does one
test to the limits shown in these two standards?
