Thank you for all responses.
Clarification for testing and report requirements. Based on the fact the
European Union, FCC and Industry Canada have endorsed CISPR 22, a test report
that covers Global requirements would be as follows.
The following assumes the use of universal power supplies or supplies with
120-230 volt settings available.
-Radiated emissions to CISPR 22-1993 using CISPR peripheral and cable
maximization procedure. To satisfy the worst case requirements,
investigative testing must be done at 120 VAC 60 Hz and 230 VAC 50 Hz.
Perform final radiated emissions testing at the worst case operating voltage.
Justify the operating voltage as the worst case configuration within the
text of the report.
-Conducted emissions is also done to CISPR 22 range of 150 kHz to 30 MHz and
testing must be performed at both 120 VAC 60 Hz and 240 VAC 50 Hz. Again use
the peripheral and cable maximization procedure for CISPR 22-1993. Report
the
conducted emissions for both voltage settings within the test report.
Once the European Commission has adopted CISPR 22-1997, all testing will use
the peripheral and cable maximization procedure outlined within the 1997
version, essentially the ANSI C63.4-1992 procedure.
[hopefully Canada will also adopt the new CISPR 22-1997 requirements for
maximization of cables and peripherals]
