10.9 Trigger Delay

The trigger delay feature lets you specify a delay that will be applied between the receipt of a

hardware acquisition start trigger or frame start trigger and it becoming effective.

The trigger delay may be specified as a time interval in the range from 0 to 1000000 µs (equivalent

to 1 s) or as a number of consecutive line start triggers where the maximum number depends on

the camera model. When the delay is set to 0 µs or 0 line start triggers, no delay will be applied.

The trigger delay will not operate when the camera is triggered by your application software and

when the camera operates in continuous frame mode (free run).

When setting the trigger delay you must specify the kind of trigger to be delayed (acquisition start

or frame start trigger) and the extend of the delay expressed as a time interval or as a number of

consecutive line start triggers.

You can set the trigger delay from within your application software by using the pylon API. As

examples, the following code snippets illustrate using the API to set the delay for the acquisition

start trigger to 1000 µs and to set the delay for the frame start trigger to 100 line start triggers:

// Trigger delay

Camera.TriggerSource = AcquisitionStart;

double TriggerDelay_us = 1000.0 // 1000us == 1ms == 0.001s;

Camera.TriggerDelaySource = TriggerDelay_us;

Camera.TriggerDelayAbs.SetValue( TriggerDelay_us );

// Trigger delay

Camera.TriggerSource = FrameStart;

int NumberLineTriggers = 100;

Camera.TriggerDelaySource = LineTrigger;

Camera.TriggerDelayLineTriggerCount.SetValue( NumberLineTriggers );

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

You can also use the Basler pylon Viewer application to easily set the parameters.
