Parameter Description
In line-scan system, this parameter declares the device responsible for line rate generation.
For more information, refer to Line rate modes.
When LineRateMode is set to PERIOD, the downweb line rate is controlled by the Period_us parameter.
When LineRateMode is set to EXPOSE, the downweb line rate is controlled by the Expose_us parameter.
When LineRateMode is set to PULSE or CONVERT, the downweb line rate is directed by a pulse signal applied to line trigger hardware line selected by the LineTrigLine parameter.
The applicable line rate modes are depending on the selected LineCaptureMode and on the camera line-scanning mode. The camera line-scanning mode is determined by the Expose and Readout parameters (Camera Features category). Two classes of camera line-scanning mode are considered in this case:
- Free-running cameras
- Controlled line rate cameras
