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congurationofSoftware
Acquisition Events.
Comparethetwodiagramsbelow:Therst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notication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notied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.
