7.6.11 ExposureTime
| RW | B |
Min: 1µs
Max: AquisitionFramePeriod
Set the exposure time (in 1µs steps). The exposure time is not
corrected for the light sensitive FOT of the sensor. To obtain the actual
integration time the light sensitive FOT has to be added to the
exposure time set with this feature. See section 7.6.10.1 for details
about the FOT.
This feature is automatically updated if any of the following features is changed:

7.6.13 InterfaceUtilization
| RW | B |
50% to 100%,
Increment: 1%
Decrease the data rate of the interface in order to prevent the frame
grabber from being overrun. Example: a utilization factor of 50 halves the
available interface bandwidth.
The utilization factor does not change the interface configuration (
ConnectionConfig
) but creates an
empty period in between the readout of lines. An example of the utilization factor is shown in Figure 7-8.
When lowering the utilization factor the line readout period will increase which directly influences the
duration of the frame output. The maximum achievable frame rate after changing the utilization factor
can be requested with the
AcquisitionMaxFramerate
feature.
Example: 50% utilization factor is a doubling of the readout time of one line with respect to the fastest
line readout period (100%). The maximum frame rate will thus reduce by 50% if the frame grabber is the
limiting data transfer factor.
