The timing tables accompanying each of the triggering diagrams that follow indicate the exposure and cycle times
achievable in each triggering mode. These are based on Frame and Row Periods as shown below.
Timing Parameters based on Sensor Clock Speed :
1 Row 6.6 μs (16-bit) 11.2 μs (12-bit)
1 Full Frame (2048 rows) 13.5 ms (16-bit) 22.9 ms (12-bit)
Note: A single row can be read in 16-bit mode.
In External and External Start Triggering Modes, the minimum trigger pulse width detected by the camera is:
Minimum EXT Trigger Width
EXT Trig Pulse Width 10 ns

Internal Trigger Mode allows the user to configure an exposure time and cycle time. For Internal Triggering Non-overlap
mode, the exact acquisition sequence depends on the exposure time and cycle time set as shown in Figures 7 and 8.
The following diagrams show the behaviour of TTL outputs ‘Fire’, Fire n’, ‘Fire ALL’ and ‘Fire ANY’.
Fire ALL indicates the time period within a frame during which all rows are exposing simultaneously.
Fire ANY indicates the time period within a frame during which any row is exposing.
