by establishing quasi-peak and mean value limits for fre-
quencies ranging from 30MHz to 40GHz (or maximum
frequency's fifth harmonic, whichever is lower).
For AC main ports, the FCC Part 15 regulation controls
main terminal interference voltage by establishing quasi-
peak value limits for frequencies ranging from 450kHz to
30MHz.
