Hello group,
Part 15, section 109, states that as an alternative to the radiated emission limits shown in paragraphs (a) and (b) of this section, digital devices may be shown to comply with CISPR22 3rd ed. Further-on is stated that the testmethods of part 15 (referring to ANSI C63.4) apply. Question: If a lab performs Part 15 measurements for Class B devices below 1000MHz according to CISPR22:1997 with - the limits of CISPR22 - the procedures of CISPR22 - at a 10 meter distance as per CISPR22, Are these measurements performed in an correct way? Regards, Kris Carpentier
