 The tighter limit applies at the edge between two frequency bands.
 Distance refers to the distance in meters between the measuring instrument antenna
and the closed point of any part of the E.U.T.
 The limits from 30 to 1000 MHz are referred by CISPR 32 standard, which are equival
entto or more restrictive than the comparable FCC limits. It is accepted by FCC
response on 1/14/2021 (Tracking number 603131).
 The limits above 1GHz are referred to FCC Part 15.109(a)
 Required highest frequency for radiated measurement

FCC is 5th harmonic of the unintentional
highest frequency or 10th harmonic of the
intentional highest frequency ,whichever is
higher(up to 40GHz).
