The Office of Engineering and Technology (OET) of the U.S. Federal Communications Commission has published an updated version of its frequently asked questions (FAQs) about its regulations applicable to AC power-line conducted emissions testing.
The FAQs document on AC power-line conducted emissions testing provides clarification on a number of testing issues related to the FCC’s applicable regulations. Specific questions addressed in the document include what is required to demonstrate compliance when a device has both quasi-peak and average limits for AC power-line conducted emissions, and how an RF power output of an intentional radiator should be configured when conducting AC power-line conducted emissions measurements.
Published in June 2015, the OET’s revised FAQs document also includes information on the type of USB power source required for measuring AC power-line conducted emissions when the device is powered by a USB connection (Question #8). The revised FAQs document also includes a footnote that addresses the use of new editions of ANSI C63.4 and ANSI C63.10.
