1
Frequencies are referred to the central frequency for an 8 MHz channel. Peak levels measured using a 10 kHz
bandwidth are referred to the carriers located on either side of the spectrum. Values shown are the worst case and
correspond to guard intervals of 1/32.
2
Value measured in master mode. In slave mode, the MER is greater than 38 dB for 8 MHz channels, and around 35
dB for 7 and 6 MHz.
