2315NDT v2 CMOS X-ray Detector User Manual
Triggering the detector is the attempt to synchronize the detector to other devices, for example,
other X-ray sources that have their specific schemes of radiating X-ray pulses. In Continuous
readout mode there are three trigger sources available:
•
Software Trigger (see
•
External Edge Trigger (see
).
•
External Duration Trigger (see
(The signal levels on the trigger connectors are shown in
Once the synchronization between Detector and the other devices involved is performed, one or
more images can be acquired in different ways (Exposure modes):
•
Expose and read (see
•
Sequence exposure (see
•
).
•
).
19.1.1
Continuous Readout - Software Trigger
In Software Trigger, the trigger is sent by the software (SCap or API function). In SCap, this
mode is selected using Configuration – External Trigger – Software Trigger and following the
sequence below (see
Figure 8, “Continuous readout - Software Trigger Schematic,” on page 28
.
Values are displayed in
