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.

Imaging	CamConfig	LineCaptureMode	LineRateMode
AREA	-	Irrelevant	Irrelevant
LINE	LxxxxSP LxxxxSC	ALL	CAMERA (*)
LINE	LxxxxSP LxxxxSC	PICK	PERIOD PULSE CONVERT (*)
LINE	LxxxxRP	ALL	EXPOSE () PULSE () CONVERT (*)
LINE	LxxxxRP	PICK	PERIOD PULSE CONVERT (*)
LINE	LxxxxRC LxxxxRG LxxxxRG2	ALL	PERIOD (*) PULSE CONVERT
TDI	LxxxxSP LxxxxRP	ALL	EXPOSE () PULSE () CONVERT (*)
TDI	LxxxxSP LxxxxRP	ALL	PERIOD PULSE CONVERT (*)

(*) Default value.

(**) These values are allowed by MultiCam but are not recommended since the sensitivity of the camera is varying with the line rate.
