could you explain what +8dB stands for (what is 0dB ? ) ?12498H +8dB
0dB is the baseline, i.e. the noise floor. So the dB figure is carrier to noise. FEC 2/3 is resolveable from about 5.5dB. Also expressing in dB is an easy way to relate to everyone else's charts.could you explain what +8dB stands for (what is 0dB ? ) ?
Do you have a lock? Otherwise there's not much relationship to S/N or C/N ;)So the dB figure is carrier to noise
There's no lock because it is not a DVB transmission. But this is how carrier to noise is measured for analogue, and if I measure a digital transponder the same way and then switch to digital parameters SNR will be more or less the same, or maybe just a tad lower. Anyway, at the very least, it's an easy way for the others who are catching spectrums to compare my power levels with theirs.Do you have a lock?

it look spot beam for me weak signal
