Maximum PA
VSWR
Defines the upper limit for the VSWR. When the VSWR exceeds this limit,
the base station triggers the alarm VSWR high and the Task Manager input
VSWR fault becomes true. The hysteresis is fixed at 0.2. For example, if the
threshold is 1.5:1, when the VSWR falls to 1.3:1, the alarm is cleared and the
Task Manager input becomes false.
Maximum PA final
temperature
Defines the upper limit for the operating temperature at the Final 1 and Final 2
stages of the PA. When the temperature exceeds this limit, the base station
triggers one of the Temperature high alarms and the Task Manager input PA
temperature high becomes true.
Maximum PA
driver
temperature
Defines the upper limit for the operating temperature at the driver stage of the
PA. When the temperature exceeds this limit, the base station triggers one of
the Temperature high alarms and the Task Manager input PA temperature high
becomes true.
PA air intake
temperature
The Maximum box defines the upper limit for the air intake temperature that
is measured at the PA. When the temperature exceeds this limit, the base station
triggers the Air intake temperature high alarm and the Task Manager input PA
air intake temperature high becomes true.
The Minimum box defines the lower limit for the air intake temperature that
is measured at the PA. When the temperature falls below this limit, the base
station triggers the Air intake temperature low alarm and the Task Manager
input PA air intake temperature low becomes true.
PMU battery
voltage
The Max box defines the upper limit for the battery voltage that is supplied to
the DC-DC converter. Different limits apply, depending on which nominal
voltage the DC-DC converter is designed for. When the voltage exceeds the
relevant limit, the base station triggers the Battery voltage high alarm and the
Task Manager input Battery voltage high becomes true.
The Min box defines the lower limit for the battery voltage that is supplied to
the DC-DC converter. Different limits apply, depending on which nominal
voltage the DC-DC converter is designed for. When the voltage falls below the
relevant limit, the base station triggers the Battery voltage low alarm and the
Task Manager input Battery voltage low becomes true.
Both the upper and lower limits have a hysteresis of 0.1 V.
Balanced line
input level
The Minimum box defines the lower limit for the level of the audio signal on
the balanced line in. When the audio level falls below this limit, the base station
triggers the Balanced input low alarm and the Task Manager input Balanced
input low becomes true.
Unbalanced line
input level
The Minimum box defines the lower limit for the level of the audio signal on
the unbalanced line in. When the audio level falls below this limit, the base
station triggers the Unbalanced input low alarm and the Task Manager input
Unbalanced input low becomes true.
RSSI level The Maximum box defines the upper limit for the received signal strength as
measured in the receiver. When the RSSI exceeds this limit, the base station triggers
the
RSSI high alarm and the Task Manager input RSSI high becomes true.
The Minimum box defines the lower limit for the received signal strength as
measured in the receiver. When the RSSI falls below this limit, the base station
triggers the RSSI low alarm and the Task Manager input RSSI low becomes
true.
