(3) Exposure time setting: External [EMD L]
Exposure begins within 2 µs from the fall {rise} of the external trigger pulse. After this,
when external trigger pulse rises {falls} again, the exposure is stopped within 27 µs,
and the data is read out. 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 + external control pulse's LO interval {HI
•
Note
Set the external control pulse's repeat cycle so that it is longer than the minimum cycle.
Maximum exposure time is 1 s. When the external control pulse's LO interval {HI
interval} exceeds 1 s, the exposure is stopped and the data is read out (exposure
cannot exceed 1 s).

The external control pulse's LO interval {HI interval} must be at least 100 μs.
