CDM-710G High-Speed Satellite Modem Revision 1

Eb/No Measurement MN-CDM710G

B–3

Table B-1. CDM-710G Co+No/No to C/N (Es/No) and Eb/No (dB) for DVB-S2 QPSK and 8PSK

(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.
