9.5.3.3 Frame Start Trigger Delay
The trigger delay feature lets you specify a delay (in microseconds) that will be applied between the
receipt of a hardware frame start trigger and when the trigger will become effective.
For more information about the trigger delay feature and how to use it, see Section 11.10 on
page 193.
9.5.3.4 Setting the Parameters Related to Hardware Frame Start
Triggering and Applying a Hardware Trigger Signal
You can set all of the parameters needed to perform hardware frame start triggering from within your
application by using the Basler pylon API. The following code snippet illustrates using the API to set
the camera for single frame acquisition mode with the trigger mode for the acquisition start trigger
set to off. We will use the timed exposure mode with input line 1 as the trigger source and with rising
edge triggering. In this example, we will use a trigger delay:
// Set the acquisition mode to single frame
Camera.AcquisitionMode.SetValue( AcquisitionMode_SingleFrame );
// Select the acquisition start trigger
Camera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );
// Set the mode for the selected trigger
Camera.TriggerMode.SetValue( TriggerMode_Off );
// Select the frame start trigger
Camera.TriggerSelector.SetValue( TriggerSelector_FrameStart );
// 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 trigger activation mode to rising edge
Camera.TriggerActivation.SetValue( TriggerActivation_RisingEdge );
// Set the trigger delay for one millisecond (1000us == 1ms == 0.001s)
double TriggerDelay_us = 1000.0;
Camera.TriggerDelayAbs.SetValue( TriggerDelay_us );
// Set for the timed exposure mode
Camera.ExposureMode.SetValue( ExposureMode_Timed );
// Set the exposure time
Camera.ExposureTimeAbs.SetValue( 3000 );
// Execute an acquisition start command to prepare for frame acquisition
The trigger delay will not operate if the Trigger Mode parameter for frame start is
set to off or if you are using a software frame start trigger.
