Level measurement of the currently tuned carrier.
Ratio between the modulated signal power and the equivalent
noise power for a same bandwidth.
Automatic method.
Ratio between the modulated signal power and the equivalent
noise power for a same bandwidth.
Modulation Error Ratio. Complementary measurement of the
Noise Margin for DVB-S and the Link Margin for DSS.
The BER measurement (Bit error rate) for the digital signal
before error correction (BER before FEC).
(Only for DVB-S and DSS) The BER measurement (Bit error
rate) for the digital signal after error correction (BER after
Viterbi).
(Only for DVB-S2) The BER measurement (Bit error rate) for
the digital signal after error correction (BER after LDPC).
