Trigger operation and timing chart

External trigger refer to a function for picking up rapidly moving objects by applying a trigger pulse input. It is possible to pick up an image with various timing.

1. HV-F31F

(1) External trigger operating mode: Mode 0

When external trigger signal is high active,

light pulse begins at the rising edge of the

trigger signal and ends at the falling edge.

At the trigger signal falling edge, the

internal VD signal is reset and the video
