CDM-710 Broadcast Satellite Modem Revision 11

Eb/No Measurement MN/CDM710.IOM

B–4

Table B-2. CDM-710 Co+No/No to C/N (Es/No) and Eb/No (dB) For DVB-S2 QPSK and 8-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.
