Set a frame trigger

Internal frame trigger

The internal frame trigger provides a continuous signal after each acquired image.

1. In the Configuration window navigate to Acquisition Control → Frame Trigger.
2. 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:

External frame trigger

The external frame trigger can be provided by a light barrier.

1. In the Configuration window navigate to Acquisition Control → Frame Trigger.
2. Below External select the Use external source to generate frame trigger checkbox.

In Trigger Selector select the desired activation mode.  In Trigger Activation select the desired trigger activation mode.  In Trigger Source select the desired input Line.  In Line Format select the electrical input signal. In Signal detection select the detection mode.   In Trigger Delay Lines input the delay of the trigger in lines.

Alternatively, you can set the external frame trigger in the camera feature tree by executing the following steps:

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

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. 

Input signal activation: Frame active

Frame burst start

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 activation 

The TriggerActivation specifies the activation mode of the trigger.

Frame Start	Frame Burst Start	Frame Active

Trigger Source 

The TriggerSource specifies the input line to use as a trigger source, please refer to the electrical installation.

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 four options are available:

PeakholderDetection 

The Trigger signal detection mode → PeakholderDetection detects every small input signal and starts the image acquisition immediately.

PeakholderDetection  

Debouncing4Lines

The Trigger signal detection mode → Debouncing4Lines requires a 4-line stable trigger input signal, this leads to an image delay of 4 lines.

Debouncing4Lines  

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. 

Debouncing4Clocks  

Trigger Delay Lines

Specifies the delay in the number of lines to apply after the trigger reception before activating it.

Line Format 

The Digital IO Control → Line Selector → Line Format controls the electrical format of the selected physical input. For the specific electrical format, please refer to the electrical installation.
