CDM-710G High-Speed Satellite Modem
Revision 1
Eb/No Measurement
MN-CDM710G
B–4
Table B-2. CDM-710G Co+No/No to C/N (Es/No) and Eb/No (dB) for DVB-S2 16APSK and 32APSK
(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.
