Detection of Tx Malfunction
A built-in lock detector (high active) is used to monitor the local os-
cillator (PLL circuit) of the transmitter. If the operation of PLL circuit
becomes abnormal, a logic low (TX malfunction) will be sent from
the lock detector to notify the system. At the same time, system will
also output an ALR 001 at the related PI port.
Detection of Rx Malfunction
The V5035 also has 3 built-in lock detectors (high active) to monitor
each local oscillator (PLL circuit) of receiver channel 1, channel 2,
and channel 70 respectively. If the operation of PLL circuit becomes
abnormal, a logic low level will be sent from the lock detector to
notify the system. At the same time, the system will output ALR 003
or ALR 004 or ALR 005 at the related PI port to indicate the CH1 or
CH2 or CH70 RX malfunctions respectively.
