Triggering Example 6
Immediate multiple-phase
Area-scan, asynchronous reset
With phase overlapping
This triggering modality is reached when the following combination of parameters is set:
MultiCam parameter |
Value |
ALLOW |
|
IMMEDIATE |
|
HARD |
|
MC_INDETERMINATE, >1 |
This example shows the way to grab several successive images from an asynchronously reset camera using an external frame trigger.
The initial trigger event (TE) is directly caused by the software-issued SAS event. There can be a substantial delay between the SAS and SWP events due to the software overhead implied in opening the acquisition sequence.
The subsequent trigger events are sourced by a hardware- or software-issued event. There is no substantial delay between the source and subsequent SAP events.
Use this triggering mode with NextTrigMode set to SOFT for software-controlled subsequent grabs if a tight timing is to be met.
Specify the number of images to be acquired in a row with the parameter SeqLength_Fr. To acquire an undefined number of images, set SeqLength_Fr to MC_INDETERMINATE. In this case, the sequence will be stopped by returning the MultiCam channel to the idle state.
