velocity measurement. It is identical to the Standard mode
but, the camera will capture only 2 frames after each trigger
signal. There is no delay between the frames
4. Frame Accumulation – in this mode, after each trigger signal
the camera starts integration then transfers the information to
the vertical registers and then waits for the next trigger. After
the last trigger has been received the information is being
read out.
5. Asynchronous – in this mode the camera is free running prior
to the trigger. When the trigger is applied, it resets the CCD
timing, flushes the remaining lines and starts the integration.
Trigger Edge
– the user can select the active triggering edge:
1. Rising – the rising edge is used for triggering.
2. Falling – the falling edge is used for triggering.
Trigger Overlap
– the user can select how to handle the next
trigger pulse if arrives while the previous triggering cycle is in
process:
1. Ignore – the next rigger will be ignored, and the camera will
continue its present operation.
2. Accept – the next trigger will be used.
3. Accept after Exposure – the next rigger will be ignored while
the camera is exposing the image.
De-bounce
– the trigger inputs are de-bounced to prevent
multiple triggering from ringing triggering pulses. The user has
four choices of de-bounce interval:
1. Off – No De-bounce.
2. 0.1 ms – 100 us de-bounce interval (by default).
3. 1.0 ms – 1 ms de-bounce interval.
4. 10.0 ms – 10 ms de-bounce interval.
Acquisition:
Frames per trigger
– sets the number of frames captured after
each trigger in “Standard” mode. The user can select from 1 to
65500 discrete frames to be captured. If the value is 65501 or
bigger, the camera is free running after the trigger signal.
