USER’S MANUAL. TV EXPLORER HD +C/NFM DeviationRatio between the modulated signal power and the equivalentnoise power for a same bandwidth. (according to TV standard)Measure the frequency peak deviation for any modulatedanalogue carrier in FM.Terrestrial band - Digital channels (DVB-C, DVB-T/H and DVB-T2):Channel powerChannel power is measured assuming that power spectraldensity is uniform throughout channel bandwidth.To measure it correctly it is indispensable to define theChannel BW.C/N Out-channel measurement. Noise level is measured at f noise =f tuning ± ½*Channel BW. To measure it correctly digital channelmust be tuned at its central frequency.MERModulation error ratio with noise margin indication.CBERVBER(only for DVB-T/Hand DVB-C)BER measurement (Bit error rate) for the digital signal beforeerror correction (BER before FEC).BER measurement (Bit error rate) for the digital signal beforeerror correction (BER before Viterbi).LBER(only for DVB-T2)BER measurement (Bit error rate) for the digital signal after errorcorrection (BER after LDPC).Satellite band - Analogue channelsLevelC/NLevel measurement of the currently tuned carrier.Ratio between the modulated signal power and the equivalentnoise power for a same bandwidth.Satellite band - Digital channels (DVB-S/S2):Channel PowerC/NMERCBERAutomatic method.Ratio between the modulated signal power and the equivalentnoise power for a same bandwidth.Modulation Error Ratio.
