8.2.6 Use Case Descriptions and Diagrams

The following pages contain a series of use case descriptions and diagrams. The descriptions and

diagrams are designed to illustrate how acquisition start triggering, frame start triggering and line

start triggering will work with common combinations of parameter settings.

These use cases do not represent every possible combination of the parameters associated with

acquisition start, frame start, and line start triggering. They are simply intended to aid you in

developing an initial understanding of how triggers and parameters interact.

In each diagram, the black box in the upper left corner indicates how the parameters are set. Note

that the number of lines per frame parameter (Height), is set to three for each diagram. This is not

realistic, but is used in the diagrams so that they will more conveniently fit onto a single page.

Use Case 1 - Acquisition Start, Frame Start, and Line Start Triggering Off

(Free Run), Single Frame Mode

Use case one is illustrated on page 117.

In this use case, the Acquisition Start Trigger Mode, the Frame Start Trigger Mode, and the Line

Start Trigger Mode parameters are all set to off. The camera will internally manage acquisition start,

frame start, and line start trigger signals. When the camera is set this way, it will acquire lines

without any need for triggering by the user. This use case is commonly referred to as "free run".

The rate at which the camera will acquire lines will normally be determined by the camera’s

Acquisition Line Rate Abs parameter. If the Acquisition Line Rate Abs parameter is disabled, the

camera will acquire lines at the maximum allowed line rate.

In this example, each frame is set to include three lines.

When the Acquisition Mode is set to Single Frame, an acquisition start command must be issued

for the acquisition of each single frame.
