I think you overlooked a detail. The FCC allows you to use the LIMITS of
CISPR 22, but requires the ANSI TEST METHODS with regards to cable
manipulation, etc. Since the CISPR 22 techniques are relatively
unspecified and are being modified in committee to match ANSI C63.4, a
test report for all countries would use the CISPR 22:1993 limits and the
ANSI test methods now.
