ROI frame rates
Values were calculated as defined in
To reach the maximum frame rate available for this setup, the bandwidth for image
traffic is 200 MBps. Increasing the
DeviceLinkThroughputLimit
value does not
increase frame rates.
Alvium 1800 U-120 cameras do not allow overlapping of exposure and readout.
In triggered mode
, the maximum available frame rates may be reduced with long
exposure times.
