(2) Exposure time setting: Internal / Absolute Time [EMD T, AET ss.xxx]
Exposure begins within 2 µs from the fall {rise} of the external trigger pulse, the
exposure is made using the time set with the AET ss.xxx command, and readout
follows. After readout, the system waits for the external trigger pulse to fall {rise} again.
The exposure time is set with the AET ss.xxx command (where s = seconds, x =
milliseconds). The actual length of exposure time is the specified time taken as a value
expressed in horizontal scan units. Exposure time longer than 1 s is not possible. The
repeat cycle is controlled by the external control pulse's repeat cycle, but the minimum
cycle is calculated as shown below. Set the external control pulse's repeat cycle so that
it is longer than the minimum cycle.
Minimum repetition time = readout time + set exposure time
