6.3.2 Acquisition Burst Frame Count
When the Trigger Mode parameter for the frame burst start trigger is set to on, you must set the
value of the camera’s Acquisition Burst Frame Count parameter. The value of the Acquisition Frame
Count can range from 1 to 255.
With frame burst start triggering on, the camera will initially be in a "waiting for frame burst start
trigger" acquisition status. When in this acquisition status, the camera cannot react to frame start
trigger signals. If a frame burst start trigger signal is applied to the camera, the camera will exit the
"waiting for frame burst start trigger" acquisition status and will enter the "waiting for frame start
trigger" acquisition status. It can then react to frame start trigger signals. When the camera has
received a number of frame start trigger signals equal to the current Acquisition Burst Frame Count
parameter setting, it will return to the "waiting for frame burst start trigger" acquisition status. At that
point, you must apply a new frame burst start trigger signal to exit the camera from the "waiting for
frame burst start trigger" acquisition status.
6.3.3 Setting the Frame Burst Start Trigger Mode and
Related Parameters
You can set the Trigger Mode and Trigger Source parameters for the frame burst start trigger and
also set the Acquisition Burst Frame Count parameter value from within your application software
by using the Basler pylon API.
The following code snippet illustrates using the API to set the Trigger Mode to on, the Trigger
Source to software, and the Acquisition Burst Frame Count to 5:
// Set the acquisition mode to Continuous (the acquisition mode must
// be set to Continuous when frame burst start triggering is on)
camera.AcquisitionMode.SetValue( AcquisitionMode_Continuous );
// Select the frame burst start trigger
camera.TriggerSelector.SetValue(TriggerSelector_FrameBurstStart);
// Set the mode for the selected trigger
camera.TriggerMode.SetValue( TriggerMode_On );
// Set the source for the selected trigger
camera.TriggerSource.SetValue ( TriggerSource_Software );
// Set the acquisition burst frame count
camera.AcquisitionBurstFrameCount.SetValue( 5 );
The following code snippet illustrates using the API to set the Trigger Mode to on, the Trigger
Source to Line 1, the Trigger Activation to rising edge, and the Acquisition Burst Frame Count to 5:
// Set the acquisition mode to Continuous (the acquisition mode must
// be set to Continuous when frame burst start triggering is on)
