BER after Viterbi.
CSI (Channel Status Information). Qualitative
measurement about channel quality. Measures
from 0 to 100 %. 0 % value corresponds to
maximum quality.
Numeric and level bar.
BER before FEC (Forward Error Correction).
MER (Modulation Error Ratio).
Numeric and level bar.
BER before Viterbi.
BER after Viterbi.
Numeric and level bar.
Number of non-correctable packets accumulated
during the measurement time, and indicates when
the fault was produced.
Identification according to levels 1.1, 1.2, 1.3 and
2.1 of TR 101 290 ETSI standard.
DVB channel identifier. Provides information on the
channel whose BER is being measured.
2k / 8k (Selected by the user).
1/4, 1/8, 1/16, 1/32 (Selected by the user).
1/2, 2/3, 3/4, 5/6, 7/8.
QPSK, 16-QAM, 64-QAM.
Selectable: ON, OFF.
Indicates hierarchy mode.
Reed-Solomon (204, 188) and Viterbi.
