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. 14 through fig. 19 and fig. 22 & 23.
To use this mode:
Set function:
Trigger mode to “Pulse width control”.
TR=2
Partial scan
SC=0 to 5
Programmable Partial
PRGP-0 or 1
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 duration > 1 LVAL (LVAL async), > 2 LVAL (LVAL sync)
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
6.1.6 for details.
3.
The minimum interval of the trigger is as follows ( in case of LVAL sync). In LVAL async
mode, the exposure period should be added.
