This read-only object reports one of three LNB fault states: no faults(0), LNB current fault(7), or LNB voltage fault(9). This distinguishes an LNB power-supply-related fault from an RF-signal-related fault reported elsewhere, like cdd564RxAlarm -- a current or voltage alarm here means the physical LNB power feed itself has a problem, likely a failing LNB, damaged cable, or connector fault, rather than a signal or pointing issue, even if the demodulator downstream also shows a lock failure as a consequence. If this object reports lnbCurrent(7) at the same time the demodulator alarm reports demodulatorUnlocked(1), the LNB power fault is likely the root cause of the demodulator's failure to lock, since without proper LNB power the antenna simply isn't downconverting the signal.
