Several oscilloscope channel trigger types can have an additional trigger condition and corresponding trigger condition time. Some trigger conditions have two trigger times, defining a trigger condition time frame. The following trigger conditions are available:
| Trigger condition | Description |
|---|---|
| None | there is no additional trigger condition. |
| Shorter than | the signal requirements defined by the trigger type must last shorter than the specified trigger condition time to cause a trigger. |
| Longer than | the signal requirements defined by the trigger type must last longer than the specified trigger condition time to cause a trigger. |
| Inside | the length that the signal requirements defined by the trigger type last, must be inside the trigger condition time frame to cause a trigger. |
| Outside | the length that the signal requirements defined by the trigger type last, must be shorter than or longer than the trigger condition time frame, in other words outside the trigger condition time frame to cause a trigger. |
Setting the trigger condition in the Multi Channel oscilloscope software can be done in several ways:
- Using the Condition selector in the trigger properties dialog.
- Right-clicking the trigger symbol on an axis or the associated channel in the Object Tree and selecting Trigger condition and then the required value in the popup menu.
Trigger condition time(s)
The trigger condition time specifies the duration of a specific signal condition, in seconds. When two trigger condition times are available, the two times define a trigger condition time frame, in seconds.
Setting the trigger condition time(s) in the Multi Channel oscilloscope software can be done in several ways:
- Entering the required value in the Condition time or Condition time 2 box in the trigger properties dialog.
- Right-clicking the trigger symbol on an axis or the associated channel in the Object Tree and selecting Trigger condition time or Trigger condition time 2 in the popup menu. The time is entered in seconds.
