2315NDT v2 CMOS X-ray Detector User Manual
To make sure there is no overlap of the T
XRAY
with the frame readout, it is recommended to have
T
XRAY
configured shorter than T
EW
, so as to allow some delay time prior to X-ray
exposure and some tail time afterwards.
In some generators, there may be a delay between asserting Sync Out 2 and the actual start of
X-ray emissions. This must be compensated by increasing the programmed exposure window
T
EW
, so that the frame readout does not start before the X-ray emission has finished.
The frame readout time and fps of 2315NDT detectors are shown in
shows an example of the Software Trigger configuration.

Sync Connection for Software Trigger
In this case, the generator is informed that the detector is ready to receive the X-ray emission
when the Sync Out level changes.
