Pulse Width Trigger Mode
In this mode the accumulation time is equal the trigger pulse width. Here it is possible to have
long time exposure. The maximum recommended time is <60 frames.
For timing details, refer to fig. 16 through fig. 21 and fig. 24 & 25.
To use this mode:
Set function:
Trigger mode to “Pulse width control”.
TR=2
Partial scan
SC=0 to 4
Vertical binning
VB= 0 or 1
Other functions and settings
Input:
Ext. trigger. Camera Link or 12-pin Hirose TI=0, TI=1
Important notes on using this mode
1.
The minimum trigger interval > 1 LVAL
2.
Depending on the timing of the leading edge of the trigger pulse in relationship to FVAL,
accumulation will be synchronous or a-synchronous in relationship to LVAL. See chapter
6.1.1 for details.
