Internal frame trigger
The internal frame trigger provides a continuous signal after each acquired image.
In the Configuration window navigate to Acquisition Control → Frame Trigger.
Below Internal select the Generate frame trigger continuously after each acquired image checkbox.
Internal frame trigger
Alternatively, you can set the internal frame trigger in the camera feature tree by executing the following steps:
Step | Feature name | Value |
|---|---|---|
1 | Trigger Selector | FrameActive |
2 | Trigger Mode | Off |
3 | Trigger Selector | FrameStart |
4 | Trigger Mode | Off |
5 | Trigger Selector | LineStart |
6 | Trigger Mode | Off |
External frame trigger
The external frame trigger can be provided by a light barrier.
In the Configuration window navigate to Acquisition Control → Frame Trigger.
Below External select the Use external source to generate frame trigger checkbox.

Alternatively, you can set the external frame trigger in the camera feature tree by executing the following steps:
Step | Feature name | Value |
|---|---|---|
1 | TriggerSelector | FrameStart, FrameActive or FrameBurstStart |
TriggerMode | On | |
2 | TriggerSource | e.g. Line 3 or Line 4 |
3 | TriggerActivation | level high/level low, |
4 | TriggerDelayLines | <number of lines> |
5 | TriggerSignalDetectionMode | peakholder detection, |
6 | Digital I/O Line Selector | select the trigger source |
7 | Line Format | open the drop-down menu and change the Line Format to your input signal |
Trigger Selector
Frame start
The Input signal activation → Frame start triggers the image acquisition after the Trigger delay lines and depending on the Trigger signal detection mode configuration for the duration of the image height setting. One frame trigger creates one image with a constant image height.
Input signal activation: Frame start
Frame active
Note
This configuration is only for the GigE Version available. CxP does not support this configuration.
The Input signal activation → Frame active triggers the image acquisition after the Trigger delay lines and depending on the Trigger signal detection mode configuration for the duration of the Trigger signal. One Frame trigger creates one image with the length of the frame active signal.
Frame burst start
Note
In Frame burst start mode the camera acquires multiple gapless images.
The Input signal activation → Frame burst start triggers the image acquisition after the Trigger delay lines and depending on the Trigger signal detection mode configuration for multiple times the duration of the image height setting. One frame burst creates multiple images with a constant image height.
The number of acquired images is set under Acquisistion Control → Acquisistion Burst Frame Count.
Input signal activation: Frame burst
Trigger signal detection mode
The camera supports four different Trigger signal detection modes. This configuration parameter defines the signal debouncing of the frame trigger input signal.
To set the Trigger signal detection navigate to the camera feature tree → Acquisition control → Trigger selector. The following 4 options are available:
PeakholderDetection
The Trigger signal detection mode → PeakholderDetection detects every small input signal and starts the image acquisition immediately.
Debouncing4Lines
The Trigger signal detection mode → Debouncing4Lines requires a 4 line stable trigger input signal, this leads to an image delay of 4 lines.
Debouncing60Lines
The Trigger signal detection mode → Debouncing60Lines requires a 60 line stable trigger input signal, leading to an image delay of 60 lines.
Debouncing60Lines
Debouncing4Clocks (not recommended)
The Trigger signal detection mode → Debouncing4Clocks requires a 4 clocks (clks) stable trigger input signal, leading to an image delay of 4 clocks.
