6.3.3.
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 <240 frames ( 2 seconds).
For timing details, refer to fig. 8 through fig. 13 and fig. 16 & 17.
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 6.1.5. for details.
