Trigger Operation Controlled By Pulse Width (Pwc) - JAI AD-131GE User Manual

10.6.4

Trigger operation controlled by pulse width (PWC)

In this mode the accumulation time is equal to the trigger pulse width. Here it is possible to
have a long time exposure. The maximum recommended time is <60 frames.
If the sync mode is set at ―Sync‖, the exposure time is the same for both Camera #0 and #1 as
the trigger to Camera #0 is applied to Camera #1.
In PWC mode, only LVAL asynchronous accumulation is effective.
For details of the timing, please refer to chapter 8.4 and fig. 44 and 45.
To use this mode:
Set function:
Input:
This function can be set by selecting Pulse-width control in Exposure mode of JAI Acquisition Control.
However, Acquisition Mode, Sync Mode, Exposure Time, and so on should be set.
Important Note:
The minimum duration of the trigger is 2L. The minimum period of trigger is as follows.
SYNC Mode Smearless
Enable
SYNC Mode False
=SYNC
True
SYNC Mode False
=ASYNC
