Baumer VEXG - Trigger Mode

30
7.3.5 Trigger Mode
After a specied external event (trigger) has occurred, image acquisition is started. De-
pending on the interval of triggers used, the camera operates non-overlapped or over-
lapped in this mode.
With regard to timings in the trigger mode, the following basic formulas need to be taken
into consideration:
Case Formula
t
exposure
< t
readout
(1) t
earliestpossibletrigger(n+1)
= t
readout(n)
- t
exposure(n+1)
(2) t
notready(n+1)
= t
exposure(n)
+ t
readout(n)
- t
exposure(n+1)
t
exposure
> t
readout
(3) t
earliestpossibletrigger(n+1)
= t
exposure(n)
(4) t
notready(n+1)
= t
exposure(n)
