2.6.1 Example System Usage of Acquisition Events
Software Acquisition Events are only accessible via SDK- these are not available in Solis, iQ or other software
but may be used internally. Refer to the SDK3 manual for further information on configuration of Software
Acquisition Events.
Compare the two diagrams below: The first diagram ( Figure 14 ) shows the situation prior to the introduction
of the software events. In this case the user had to wait until the image frame was completely transferred to
the PC before they received any notification that the exposure had completed. This results in a cycle time of
approximately 79 ms or a frame rate of 12.6 fps, for this example. With acquisition software events (shown in
Figure 15 ) and in particular the ExposureEndEvent the user will be notified as soon as the exposure is complete
in advance of readout completion. This in conjunction with faster SW trigger, means that the next acquisition
can be started much sooner, resulting in an improvement in frame rate, 25 fps. In addition, the Fire ALL signal
can be used to control light sources/z-stages.
