Description

CONVERT

MC_LineRateMode_CONVERT

Rate Converter – The downweb line rate is derived from a train of trigger pulses processed by a rate converter belonging to the grabber.

PULSE

MC_LineRateMode_PULSE

Trigger Pulse – The downweb line rate is directly derived from trigger pulses applied to the grabber.

PERIOD

MC_LineRateMode_PERIOD

Periodic – The downweb line rate is internally generated by a periodic generator.

CAMERA

MC_LineRateMode_CAMERA

Camera – The downweb line rate is originated by the camera.

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:
