Rad-icon 1520 Detector
Teledyne DALSA
Triggered (External) Mode
In this mode the detector will take a single image at the moment a trigger signal is
applied to the detector. This mode is equal to the Snapshot mode but no reset is needed
before integration can start.
When using pulsed X-rays, the X-ray exposure including X-ray rise- and fall-times have
to be within the “Exposure Time” window (C).
The trigger output indicates the Exposure Time window when no read-out of the sensor
occurs.
