Data Acquisition Overview
Data Acquisition (DAQ) activities accumulate user-defined data during portions of the test. The acquired
data can be:
• Saved to variables that can be used in calculations and test-run displays.
• Saved to the test file for post-test analysis, reports, or exported for use in other applications.
Data Acquisition Process
Data Acquisition activities appear in a test as:
• A standalone activity such as the DAQ activity. Standalone DAQ activities appear in the test procedure
as a path in parallel with a Command activity.
OR
• Part of a composite activity such as the Cycle + DAQ activity that combines a Command activity with
Data Acquisition.
Data Acquisition Setup
The following diagram and table provides an outline of the setup tasks and options associated with DAQ
activities.
DAQ activities accumulate data for selected signals [1]. A DAQ activity requires at least one trigger [2]
and one signal. The trigger defines when data points are stored in the buffer [3]. The buffer stores data
from the controller and then passes that data to the test application, which processes the data and saves
it to a variable [5] or saves it in the test-run file [6].
