* Random trigger shutter exposure delay time
In the random trigger shutter mode, there is an exposure delay time of approx. 2.6 µs from the falling
edge of the TRIG signal to the start of exposure in both the FIX mode and pulse width mode.
* Pulse width mode exposure time
In the random trigger shutter and pulse width modes, the exposure time is determined depending on
the pulse width, but the actual exposure time is pulse width + 8.6 µs.
