Caution #4
Consult the Technical Specications for details about the required electrical characteristics of
the trigger signal.
The EIGER2 detector systems also support external triggering. In the trigger_mode ’exts’, nimages are recorded
per trigger until ntrigger are received. Both count_time as well as frame_time are dened by the conguration.
Example detector conguration for externally triggered exposure series:
detector | cong | trigger_mode {”value”: ”exts”}
detector | cong | nimages {”value”: 10}
detector | cong | ntrigger {”value”: 1}
detector | cong | frame_time {”value”: 1.0}
detector | cong | count_time {”value”: 0.7}
