Use the Channel Configuration to monitor your signals and trigger an alarm when the
selected value conditions are met.
Select one or more channels you wish to add an alarm to.
Hover over a channel row to see the Configure gear . Click the gear for the channel you wish
to add an alarm to.
Select the Alarms tab in the Channel Configuration dialog.
Specify one of the following actions to monitor to trigger the alarm:
Table 1. Analog Channels
Rises above value
Alarm is triggered when the signal value rises above the specified
value.
Falls below value
Alarm is triggered when the signal value falls below the specified
value.
Enters range
Alarm is triggered when the signal value enters the specified
range.
Leaves range
Alarm is triggered when the signal leaves the specified range.
Table 2. Digital Channels
Is low
Alarm is triggered when the signal transitions to low (0).
Is high
Alarm is triggered when the signal transitions to high (1).
Select the alarm types you wish to enable: Critical and
Warning.
Specify the values for the alarm type you are using.
Note
If you are using both alarm types, the values specified for the
Critical alarm must be more restrictive than the
Warning alarm values.
Values are also constrained by the Physical Minimum and
Physical Maximum range specified in the Channel
Configuration. Alarm values set outside of the Physical range will be coerced to
within the set Physical limits.
For analog input channels, specify the Hysteresis, which is the
threshold relative to the alarm value, in order to prevent clearing the alarm if the data
varies due to noise or jitter in the signal.
Alarms are enabled when the test is running. Alarm conditions are not monitored when the
test is not running.
