Configures the digitizer for different types of triggering.
When you initiate an acquisition, the trigger system operates in the following manner:
- The digitizer waits for the start trigger, which is configured through the Start Trigger Source property. The default is VAL_IMMEDIATE.
- Upon receiving the start trigger, the digitizer begins sampling pretrigger points.
- After the digitizer finishes sampling pretrigger points, the digitizer waits for a reference (stop) trigger that you specify with a Configure Trigger instance.
- Upon receiving the reference trigger, the digitizer finishes the acquisition after completing posttrigger sampling.
With each Configure Trigger instance, you specify configuration parameters such as the trigger source and the amount of trigger delay. Additionally, you can adjust the amount of pretrigger and posttrigger samples using the reference position parameter in niScope Configure Horizontal Timing. The default is half the record length.
For multirecord acquisitions, all records after the first record are started based on the setting of the Advance Trigger Source property. The default is VAL_IMMEDIATE.
