5.3.2.2 (Monitor:) Rx_Stats
For DVB-S2 only:
EsNo=14.0 PER=0.0E+00
EbNo=12.8 BER=N/A T
EbNo=12.8 BER=N/A S
ΔF=-000.2k RSL=-16 T
ΔF=-000.2k RSL=-16 S
Link_Margin=+10.4
When the demodulator is locked, this menu reports Eb/No, PER (packet error rate), ΔF (frequency
offset of incoming carrier) and RSL (receive signal level).
For DVB-S and DVB-DSNG only – in this mode, BER monitoring is not available:
EsNo=16.0 PER=N/A
EbNo=15.1 BER=0.0E+00 T
EbNo=15.1 BER=0.0E+00 S
ΔF=-000.2k RSL=-16 T
ΔF=-000.4k RSL=-16 S
Link_Margin=+10.1
Link Margin corresponds to:
Standard Link Margin Threshold
