Triggering Data Acquisition

6.2.2.1

General

The data recording on the confocalDT IFD241x can be controlled using an external electrical trigger signal or com-
mands.
- The triggering does not affect the preselected measuring rate.
- Factory setting: no triggering, the controller starts with the data transmission output immediately after being switched
on.
- The pulse of the trigger signal is at least 5 µs.

. Continuous data recording/output as long as the
selected level is present. After that, the controller stops the data recording.
The pulse duration must be at least as long as one cycle. The subsequent
pause must also be at least as long as one cycle.

Triggering Measured Value Acquisition

The current array signal is only processed and measured values are calculated from it after a valid trigger event. The
measurement data is then transferred for further calculation (e.g. averaging), as well as the output via a digital or analog
interface.
When calculating averages, measured values immediately before the trigger event cannot be included; instead older
measured values are used, which had been entered during previous trigger events.
Fields with gray background require a selection.
