Figure 59: In Trigger Mode, exposure and readout times impact triggers.
B. Dual Video Trigger
If the Dual Video Trigger Option is selected, the camera outputs Frame ‘A’ continuously
until the external trigger signal is received. Upon receipt of the external trigger, the
camera switches to Frame B and outputs ‘N’ Frame Bs where is user selectable from N = 1
to 256. After outputting ‘N’ Frame Bs, the camera reverts to Frame A and outputs Frame
A’s until receipt of the next trigger input.
CAUTION: The time interval between trigger pulses must be greater than the combined
exposure and frame time. If the time between triggers is too short, then the camera will
ignore some trigger pulses
5.9 Strobes
The camera can provide up to two strobe pulses for synchronization with an external light
source, additional cameras or other peripheral devices. The user can set each strobes
pulse duration and the delay with respect to the start of the exposure time or the start of
the readout time for either Frame A, Frame B or both. The maximum pulse duration and
the maximum delay can be set up to 1 second with 1.0us precision. The strobe pulse can
be assigned to either external output. The following figure shows two strobe signals
positioned with respect to the start of exposure.
