Richard,
It was not an oversight.
Appendix B now relates to Ports, rather than equipment in general. The first
paragraph of Appendix B in issue 3 tries to explain this. Since conducted
emissions are measured on ports, it is addressed in the table. Radiated
emissions always apply whether the equipment has ports or not (i.e. an
microwave radio, or non-twisted pair or non coax ports). Thus this test is
not addressed in the table as it always applies. This is true for ESD,
Radiated Immunity, electrical safety and bonding/grounding as well (they do
not appear in the table either).
As a side note, when we re-wrote GR-1089-CORE issue 3, there are a lot of
clarifications and conceptual changes that are buried in the text. As the
caution in section 1.6 states, "This re-issue of GR contains new criteria,
extensive structural revisions, and clarifications in test procedures. Readers
are urged to review this GR carefully". This is due to the tremendous number
of subtle or minor changes which may have a significant impact on the testing
process. It is not perfect, but it is a substantial improvement over issue 2.
Hopefully this addresses your concerns,
Jim

Subject: GR-1089 Issue 3: Table B-1, missing radiated requirement?
Greetings All,
Looking through the GR-1089 Issue 3, Table B-1, the radiated emission tests
appear not apply to any type of equipment. However, the conducted emissions
are checked off for all four types of equipment. The radiated emission
sections are checked off in Issue 2 of GR-1089 as a requirement to all four
types of equipment. Does any one know if this is an oversight and the radiated
emissions should be checked off? I did not read any where in Issue 3 to find a
statement or paragraph, that would have taken the place of what would be in
Table B-1 for radiated emissions requirements.
Thanks.
Richard
