output interface. If the frame grabber is losing data, increase the line time control to
match the frame grabber acquisition rate to the Cheetah output rate.
When the Fixed Frame Period control is enabled, the user can increase the frame
time from the camera determined minimum frame time to a maximum of 1 sec, with
a precision of ~ 1.0us. In this way, the user can reduce the camera output frame rate
to match the application requirements.
2.4.2 Camera Output Control
CHEETAH camera supports the following Camera Link Outputs: Single Tap, 2-Tap,
4-Tap, 8-Tap or 10-Tap Output. This corresponds to Base, Medium, Full or Deca
Output. These camera settings combined with the output bit-depth (8, 10 or 12-bit)
to control the total the interface bandwidth. The output interface clock speed for the
Cheetah Camera is 85-MHz (Camera Link Spec is 85 MHz maximum) It is
important to match the camera’s output to the frame grabber.
Select a frame grabber or camera output based upon the following criteria of data
