Map Signals to a Variable
Variable Mapping Overview
Cycle, point-by-point, and group data acquisition activities require you to map variables to the signals you
want to acquire. Perform this mapping in the Map Variables window (for more information about the Map
Variables window, see
Map Variables Window (p. 157)).
If a variable is mapped to signal data, the data is calculated during the test run for those cycles that are
selected or defined in the properties for the data acquisition activity. The data values for each acquired
cycle are available for use in the runtime display and are saved for post-test analysis.

Signal to Variable Mapping
The following four types of data values are available for each signal that is selected for data acquisition:
• Mean
• Minimum
• Maximum
• Array
Important:
The application only calculates data for a signal if it is mapped to a variable.
The Signal to Variable Mapping panel allows you to map signals to variables.
To see the variables that are available to map, click the drop-down button.
If the Filter variables by dimension and calculation type check box is selected, the variable list includes
only the variables with the same dimension and calculation type as the signal. If the check box is clear,
all variables appear in the list.
If a variable is mapped to signal data, the data is calculated during the test run for those cycles that are
selected or defined in the properties for the Data Acquisition activity. The data values for each acquired
cycle are available for use in the runtime display and are saved for post-test analysis.
Default mapping
To automatically create new variables (if the defaults do not already exist) for selected signals and map
them to the correct signal data calculations, click the Use Default Variables button.
The name of each variable is the combination of the signal name and calculation name. The application
also copies the new variable definitions to the Variables tab.
