Edge Pre-select LVAL a-sync Timing8.5.3 Pulse Width Control Trigger ModeIn this mode the accumulation time is equal the trigger pulse width. Here it is possible to have longtime exposure. The maximum recommended time is <2 seconds.The accumulation can be LVAL synchronous or LVAL a-synchronous.The resulting video signal will start to be read out after the trigger rising edge.For timing details, refer to fig. 18. through fig. 23 and fig. 26 and 27.To use this mode:Set function: Trigger mode PWCScanning Full , PartialVertical binning ON / OFFAccumulation LVAL sync / LVAL a-syncOther functions and settingsInput: Ext. trigger.
