Set Line Rate
To set the camera‘s line rate use the line rate parameter, part of the Sensor Controls set.
This feature can only be used when the camera is in Internal mode—that is, when the start
line trigger is disabled (Trigger Mode Off).
Note: Line rate > (Exposure time + 2,000 ns) will return an error (―Invalid Parameter‖) if
this condition is not met. You must adjust these two parameters in the correct sequence to
maintain this condition.
If the external line rate exceeds 48 kHz the camera will continue to output data at its
maximum line rate of 48 kHz. Though no image artifacts associated with over-speed will
occur, you may notice that under over-speed conditions the image will appear compressed
and the apparent distance travelled will be reduced.
