6.5.3.
Pulse Width Control Trigger Mode (PWC)
In this mode the accumulation time is equal to the trigger pulse width. Here it is possible to have
a long time exposure. For best image quality, the maximum recommended time is <6 frames (2
seconds), however, depending on your application, significantly longer exposure may still produce
an acceptable signal-to-noise ratio, even without applying any external cooling.
For timing details, refer to fig. 13 through fig. 18 and fig. 20.
To use this mode:
Set function:
Trigger mode
PWC
Scanning
Normal
Programmable
Partial
scan
H, V or H+V binning
Other functions and settings
Input:
Ext. trigger
Camera Link or 12-pin Hirose
Important notes on using this mode
1.
The minimum trigger duration > 2 LVAL and the maximum duration 2 seconds (6 frames)
2.
Depending on the timing of the leading edge of the trigger pulse in relationship to FVAL,
accumulation will be synchronous or asynchronous in relationship to LVAL. See chapter
6.2.5 for details.
3.
The minimum interval of the trigger is 3331L.
