ACQUIRING DATA

5.5 - TRIGGERING MODES
The Triggering modes are selected from a drop-down list on the Setup Acquisition dialog box:
Depending on which Acquisition Mode is selected, the options available are:
• Internal
• External
• Fast External
• External Start
5.5.1 - Internal
In Internal mode, once you issue a data acquisition command, the system determines when data acquisition
begins. You can use Internal mode when you are able to send a trigger signal or ‘Fire Pulse’ to a short-
duration, pulsed source (e.g. a laser). In this case starting data acquisition also signals the pulsed source to
fire. The Fire Pulse is fed from the Fire SMB connector on the detector.
Internal Trigger Mode is also used with ‘Continuous Wave’ (CW) sources (e.g. an ordinary room light) where
incoming data, for the purposes of your observation, are steady and unbroken. This means that acquisitions
can be taken at will.
