Typical DOCSIS Performance
DOCSIS Modulation Error Ratio vs Power Output of CGH55015F
Note:
MER is the metric of choice for cable systems and can be related to EVM by the following equation:
EVM(%) = 100 x 10 ^ -((MERdB + MTAdB)/20). MTA is the “maximum-to-average constellation
power ratio” which varies with the modulation type: MTA = 0 for BPSK and QPSK; 2.55 for 16QAM
and 8QAM-DS; 3.68 for 64QAM and 32QAM-DS; 4.23 for 256QAM and 128QAM-DS
