4.4 External synchronous emission
External synchronous emission is the function to emit a strobe flash in synchronization with the
external trigger pulse.
•To activate external synchronous emission, refer to "4.2 Emission setting".
• You can set which edge of the external trigger pulse triggers emission, the rising edge or falling edge.
Refer to "4.5.3 Trigger edge setting".
• Timing (delay) from the external trigger pulse entry to strobe flash emission can be optionally set
using time and angle.

* The external trigger pulse frequency is measured per cycle and indicated (averaging procedure is
applied in every 200 ms to update the measurement value and indicate the latest one).
If the external trigger pulse cycle is beyond the specifications range, the following letters are indicated.
