TB8100 Service Kit User's Manual
The Thresholds form (Configure > Alarms > Thresholds) lets you alter the
thresholds for base station alarms.
Some alarm thresholds are fixed; they are built in to the base station and cannot
be changed. Others have default values. You may want to adjust them to better
reflect your system's operating conditions or monitoring procedures. This can
be important if an alarm is used as an input in Task Manager tasks.
The form displays a list of upper and lower limits. Alongside each threshold is
the applicable unit. To the right, a box displays the current value of the relevant
parameter. When a parameter value goes outside its limit, the base station
triggers the corresponding alarm.
To adjust a threshold, edit its value or click one of the adjacent arrows, and then
click OK to confirm your changes and close the form.
The alarms that these thresholds apply to are described in
on page 127. The equivalent Task Manager inputs are described in
Inputs" on page 180.
Defines the lower limit for the PA forward power output. When the output
falls below this limit, the base station triggers the alarm

Defines the upper limit for the PA's reverse power. When the reverse power
exceeds this limit, the base station triggers the alarm

Defines the upper limit for the VSWR. When the VSWR exceeds this limit,
