Yes, we increased the Y-Caps to get more margin. And we did!So, to qualify for a Class 1 permissive change, we'd need to show before & after data ? Applying for a Class 2 permissive change, means FCC will look only at the latest data to be sure it passes? Colorado Brian

If it's just a new supplier and the caps conform to the required component standard, there is no degradation. Reducing he capacitance would be a degradation for EMC but not for safety. Who determines the class is the person who has all the necessary data. The test house of surveillance authority check the decision.

If the filing is only for FCC, then the lab providing the report does not need A2LA accreditation,2. If the filing is for a safety report, then the lab does need A2LA accreditation. Have I got that right? We're filing some small board changes, including Y-caps and can't figure out if this is a Class 2 permissible change, defined as: " includes those modifications which degrade the performance characteristics as reported to the Commission" 3. How or who determines if our change is Class 2 (degraded performance) or Class 1? We think the results are better, but it's not like we got uniformly more margin across the board. Thanks!
