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 + 1,500 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 50 kHz the camera will continue to output data at its maximum line rate
of 50 kHz. Though no image artefacts 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.

Parameter
Description
Line Rate (in Hz)
Camera line rate in a range from 1 Hz to 50 KHz.
This feature is only available when the camera is in Internal Mode—
line trigger is disabled (Trigger Mode off).

Set Exposure Time
To set the camera‘s exposure time, use the
Exposure Time
parameter—a member of the Sensor Controls
set. This feature is only available when the
Exposure
Mode
parameter is set to
Timed
. The allowable
exposure range is from 11 µs to 3,000 µs, dependent on the value of the internal line rate.
GenICam parameters:
Sensor Controls > Exposure Time (Timed Exposure Mode) > 11 µs to 3,000 µs.
maximum line rate =
1
(exposure time + low time*)
*Exposure time must be greater than 6 µs and low time greater than 1,500 ns
