(4) Exposure time setting:
External (Synchronous readout trigger mode) [EMD S]
Exposure begins within 10 µs from the fall {rise} of the external trigger pulse. After
readout, the system waits for the external trigger pulse to fall {rise} again. The
exposure time is controlled according to the external control pulse's LO interval {HI
interval}. The repeat cycle is controlled by the external control pulse's repeat cycle, but
the minimum cycle is calculated as shown below.
Minimum repetition time = Readout time
Set the external control pulse's repeat cycle so that it is longer than the minimum cycle.

The external control pulse's LO interval {HI interval} must be at least 1 μs.
