This read-only object reports the measured Eb/No between 0 and 16 dB in 0.1 dB units, returning 999 if the demodulator is unlocked and capping at 160 for any reading above 16 dB. Functionally identical to cdd564RxEbNo, this is the primary real-time link-quality figure an admin watches during fade events or antenna adjustments, and it's the value AUPC at the far end, via cdm570AUPCRemoteDemodTargetEbNo, is ultimately trying to keep stable through automatic power compensation. A link normally running at a comfortable 10 dB Eb/No dropping to 3 dB during a storm, while AUPC at the far end raises transmit power in response, is exactly the scenario this feedback loop is designed to automatically manage.
