COFDM threshold - Edit:
Threshold level for bit error ratio before Viterbi or LDPC error
correction
Threshold level for bit error ratio before Reed-Solomon or
BCH error correction
Threshold level for bit error ratio after BCH error correction
Threshold level for signal to noise ratio (dB)
Threshold level for minimum signal strength.
This is a measure of the stream signal power. It is expressed
according to the level mode selection made in the Setup -
ETR view:
dBm: in decibels relative to a reference value of 1mW
dBuV: in decibels relative to a reference value of 1µ V
dBmV: in decibels relative to a reference value of 1mV
