Trigger rules
The User Trigger pulse width should be at least three times the width
of the Trigger Latency as indicated in Chapter Specifications on page
12.
• The end of Exposure will always trigger the next Readout.
• The end of Exposure must always end after the current Readout.
• The start of Exposure must always correspond with the Interline Time if Readout
is true.
• Expose Start Delay equals the Readout time minus the Registered Exposure
Time.
Triggering during the Idle State
For applications requiring the shortest possible Trigger Latency and the smallest
possible Trigger Jitter the User Trigger signal should be applied when Imaging is false
and Idle is true.
In this case, Trigger Latency and Trigger Jitter are as indicated in the Specifications
section.
Triggering during the Readout State
For applications requiring the fastest triggering cycle time whereby the camera image
sensor is exposing and reading out simultaneously, then the User Trigger signal should
be applied as soon as a valid Trigger Ready is detected.
In this case, Trigger Latency and Trigger Jitter can be up to 1 line time since Exposure
must always begin on an Interline boundary.
