Engineered to Endure
• Temperature (Internal)
Indicates that the internal temperature of the IBUC exceeds 85° C.
Note:
If the High Temperature Shutdown alarm has been enabled and the internal
temperature of the IBUC exceeds 85° C, the IBUC will shut down automatically
• 10 MHz Source
Indicates whether the source of the 10 MHz reference signal is internal or external.
Note:
For IBUCs operating with only an external 10 MHz reference signal, this field is
labelled “10 MHz Detector” and the options include:
•
OK (indicates that the 10 MHz signal is functioning properly)
•
Low (indicates that the 10 MHz signal is low or missing)
• PLDRO Lock
Indicates whether the phase-locked dielectric resonator oscillator (PLDRO)
frequency is locked (or stable). When the PLDRO is out-of-lock, this alarm causes
the muting of the amplifier and automatically shuts down the IBUC. Options
include:
•
OK (indicates that the PLDRO is locked and functioning properly)
•
Major
Note:
This alarm is always a major alarm and is not available for user configuration.
• AGC Range
Indicates that the automatic gain control function is unable to maintain the gain
level. Options include:
•
OK
•
Major
This alarm occurs whenever the internal AGC gain is out of range and can no
longer maintain the desired Tx Output level
•
N/A
• ALC Range
Indicates that the Tx Output level is being kept constant by the automatic level
control (ALC) function. Options include:
•
OK
•
Major
This alarm occurs whenever the internal ALC gain is out of range and can no
longer maintain the desired Tx Output level
•
N/A
Note:
Both ALC Range and ACG Range alarms are always a major and are not available
for user configuration.
