260-470 3750 to 12500 (NOTE 6) 375 to 1250
Above 470 12500 1250
NOTE:
1. The lower limit shall apply at the transition frequencies.
2. Emission level (dBµV/m) = 20 log Emission level (µV/m).
3.In the emission tables above, the tighter limit applies at the band edges.
4. Distance refers to the distance between measuring nstrument,
antenna, and the closest point of any part of the device or system.
5. Limit = 20log(56.81818(F) - 6136.3636) ; F : Fundamental Frequency (MHz)
6. Limit = 20log(41.667 x F – 7083.3333) ; F : Fundamental Frequency (MHz)
7. Limit = The Limit of Fundamental Frequency – 20dB
8. The maximum permitted unwanted emission level is 20 dB below the maximum permitted
fundamental level.
