Alarm Types
There are three types of alarm event configuration types:
1. Threshold Type
These alarm events have lower and upper limits. An alarm is raised if current reading is outside the limits.
Note:
the limits for PA Current, TX AGC, TX Reverse Power and Thermal shutdown are not user
configurable.
2. Error Ratio Type
This is the ratio of bad packets vs total packets in the defined sample duration.
For Serial, it is the ratio of bad characters vs total characters in the duration seconds. An alarm is raised if
current error ratio is greater than the configured ratio. The error ratio is configured in ‘Upper Limit’ field
and accepts value between 0 and 1. Monitoring of these events can be disabled by setting the duration
parameter to 0.
3. Sample Duration Type
Used for No Receive data events type. An alarm is raised if no data is received in the defined sample
duration. Monitoring of these events can be disabled by setting the duration parameter to 0.
See ‘Events > Events Setup’ on page 167 for setup of alarm thresholds / sample durations etc.
