The “triggered acquisition” in NIS-Elements is the process of acquiring images where some actions during the acquisition are controlled solely by hardware (TTL and analog signals, waveforms) without the software interference. Connection generally requires cables, break-out boxes and/or specialized DAQ cards or cameras. As a result, higher frame-rates can be achieved. There are the following common applications of the triggered acquisition:
A camera triggers a wavelength switcher.
A camera triggers a piezo Z stage.
A combination of the above mentioned applications - a camera triggers a Piezo Z stage and a wavelength switcher.
Note
There are also other applications such as multi camera systems where the master camera triggers slave cameras, but it exceeds the scope of this tutorial (see the Dual Andor Handbook for further info on dual cameras systems).
