7.3.5.2 Acquisition Start Trigger Delay
The acquisition start trigger delay feature lets you specify a delay (in microseconds) that will be
applied between the receipt of a hardware acquisition start trigger and when the trigger will become
effective.
The acquisition start trigger delay may be specified in the range from 0 to 10000000 µs (equivalent
to 1 s). When the delay is set to 0 µs, no delay will be applied.
To set the acquisition start trigger delay:
Set the camera’s Trigger Selector parameter to Acquisition Start.
Set the value of the Trigger Delay Abs parameter.
7.3.5.3 Setting the Parameters Related to Hardware Acquisition
Start Triggering and Applying a Hardware Trigger Signal
You can set all of the parameters needed to perform hardware acquisition start triggering from within
your application by using the Basler pylon API. The following code snippet illustrates using the API
to set the parameter values required to enable rising edge hardware acquisition start triggering with
line 1 as the trigger source:
// Set the acquisition mode to continuous(the acquisition mode must
// be set to continuous when acquisition start triggering is on)
Camera.AcquisitionMode.SetValue( AcquisitionMode_Continuous );
// Select the acquisition start trigger
Camera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );
// Set the mode for the selected trigger
Camera.TriggerMode.SetValue( TriggerMode_On );
// Set the source for the selected trigger
Camera.TriggerSource.SetValue ( TriggerSource_Line1 );
// Set the activation mode for the selected trigger to rising edge
Camera.TriggerActivation.SetValue( TriggerActivation_RisingEdge );
// Set the acquisition frame count
Camera.AcquisitionFrameCount.SetValue( 5 );
// Execute an acquisition start command to prepare for frame acquisition
Camera.AcquisitionStart.Execute( );
while ( ! finished )
{
The acquisition start trigger delay will not operate if the acquisition start trigger
mode is set to off or if you are using a software acquisition start trigger.
