CDM-710 Broadcast Satellite Modem Revision 11
Eb/No Measurement MN/CDM710.IOM
B–5
Table B-3. CDM-710 Co+No/No to C/N (Es/No) and Eb/No (dB) For DVB-S2 16-APSK and 32-APSK
(DVB-S2 uses C/N (Es/No), and Eb/No is shown for information)
Notes:
1. Eb/No = Es/No – 10 Log (Spectral Efficiency).
2. The Required C/N for QEF with FECFrame = 16,200 bits is typically 0.2 to 0.3 dB higher.
3. Shaded values are high error rate or unusable.
