Description Setting
Update Interval Note:
Applicable to cycle decimation for test-run displays only.
The speed at which data can be shown. This is useful for high-speed tests that
would otherwise require too much CPU capacity to show all data points with
high-frequency cycles. The default is 1.0 second.

Save Data to Variables Overview
The Save data to variables? data acquisition setting allows you to save (map) acquired signal data to
variables.
Cycle Data Acquisition Variables
Variables can store calculated results for signal cycle data. You must map variables to the data for the
signals that are selected for data acquisition. You must map variables to signal data if you want to use
that data in test-run displays or in the data analyzer application.
The application only calculates signal data that is mapped to a variable. The mapped data is only saved
for post-test analysis for the cycles that are defined in the data-acquisition cycle decimation filter. Variables
are mapped to signal data calculations through the Data Acquisition activity properties panel.
• Certain types of variables may represent many values in a given test. For example, a test can have a
variable in a Data Acquisition activity that is used to store the peak force value for those cycles that
are selected for data acquisition.
• Certain types of variables may represent many values in a given cycle. For example, a test can have
an array variable in a Data Acquisition activity that is used to store the force values for the
frequency-timed trigger points in a cycle.
Save data to variables requirements
With the exception of signal scopes, many aspects of a test require saving data to variables. These test
requirements include:
• Displaying signal data and calculated data on test-run displays.
• Performing calculations on signal data.
• Displaying data in reports.
