3.5.3 - Trigger options in Fast Kinetics (FK) mode
3.5.3.1 - Internal (FK)
As Fast Kinetics uses both the Image and Storage areas as temporary storage areas the number of options available is
quite limited. The simplest mode is again Internal Trigger and as with the internal trigger modes described previously

of the exposure period the cameras performs the number of vertical shifts dened by the user and then again waits for
the exposure period before the next set of vertical shifts.
This process is repeated until the number in the series has been captured at which point the read out starts. The timing
sequence is shown below and as before the Fire output envelopes the period when no vertical clocking is occurring. You
will also see there are no readout cycles or keep clean cycles running during the sequence, hence the very fast kinetic
cycle period but limited number of exposures in the series.
