Line Rate Modes
This board provides five line rate modes. The line rate mode determines the origin of the downweb line rate; it is user-selectable by means of LineRateMode:
LineRateMode |
Description |
CAMERA |
The downweb line rate originates from the camera. |
PERIOD |
The downweb line rate is internally generated by a periodic generator |
PULSE |
The downweb line rate is directly derived from trigger pulses applied to the line trigger input of the grabber. |
CONVERT |
The downweb line rate is derived from a train of trigger pulses applied to the line trigger input of the grabber and processed by a rate converter belonging to the grabber |
EXPOSE |
The downweb line rate is identical to the camera line rate are and established by the exposure time settings |
The relevant, applicable and default values of LineRateMode depend on the three following prerequisite settings: Imaging, CamConfig, and LineCaptureMode.
