Understanding and configuring the trigger settings
The trigger settings comprise a pre-trigger time, a post-trigger time, a lockout period, and a re-arming
option.
Pre-trigger Represents the recording time before the trigger condition becomes true. The
recorded data is stored in a buffer in the device.
When you select Maximum, the whole data of the buffer will be stored into the
recording. Otherwise, you can enter a value between 0 ... 10 s to limit the pre-trigger
duration and reduce the amount of data in the recording.
Post-trigger Represents the recording time after the trigger condition has been met.
When you select Unlimited, the record spans through the maximum allowed period,
which is limited by the available space of used storage. Otherwise, you can enter a
value to limit the post-trigger duration.
Lockout Represents the sleep time-period after the post-trigger period as elapsed and before
the re-arming of the device.
Re-arming Offers the option to re-arm the device after a recording.
When you select Unlimited, the device shall re-arm infinite times. Otherwise, you can
enter the number of times that the device shall re-arm.
After configuring the trigger settings, the application shows the estimated recording file size. This
estimated size excludes the traffic recordings configured in the Traffic section.
Note: The trigger settings are user desired values, which may not be fulfilled due to limited storage
space and the trigger occurrence.
Creating trigger conditions
In Trigger, you can create the trigger condition to start the recording. The trigger condition can be
based on a time stamp, on a binary or analog input measurement, or a combination of any of these
conditions. By combining several conditions you form a logical operation with a single output, which is
the trigger condition. The available logical operators are AND, OR, NAND, and NOR.
To configure the trigger condition:
1. From the Available signals, drag the appropriate signal to the Trigger condition section. A
block representing a condition for the signal appears.
2. Configure the condition. The resulting condition determines the trigger right away if there are
no further conditions to combine.
When you add multiple conditions to create the trigger condition, each one creates a new
condition-block. All blocks are then combined through a logical operator.
3. Drag the new signal to the
operator appears.
4. In the logical operator, choose the logical operation. Continue this procedure if you need to
add further conditions.
Tip: Instead of dragging the signal, double-click the signal to add it to the trigger condition in a quicker
way. The new condition-block appends to the next available input of a logical operator.
