User variable mapping
Alternatively, you can map a user-defined variable to any signal data calculation. The variable you map
must have a dimension that matches the signal data.
You cannot map a variable to a signal data calculation if the variable already contains a calculation.
However, variables that contain a calculation may optionally be used in the Additional Variables to Calculate
panel.

Additional variables to calculate
The Available Calculations panel lists variables that have a calculation. The calculations in the Selected
Calculated Variables panel are performed on those variables when the Data Acquisition activity is
performed in the test procedure. The data from the calculation is available for runtime display and for
post-test analysis.
Data for a calculated variable must exist when the calculation occurs. If a calculation is based on one or
more other variables, data must exist for those variables. If the data does not exist, the calculation cannot
be performed.
A calculation can be based on a variable that is mapped to signal data. As a result, you can perform an
additional calculation on the data at the time the data is acquired for the cycle.
To view the list of variables that contain calculations, select:
•
Signal Dependant Variables—Shows the variables that have a calculation if part of the calculation is
based on a variable that is mapped to a signal data calculation. If another variable is referenced in the
calculation, the data for that variable must exist for the calculation to succeed.
•
Calculated Variables—Shows the variables that have a calculation. This option enlarges the variable
selection scope. As a result, you must be careful to make sure that all calculation references are
resolved.
•
All Variables—Shows all variables, including variables that do not have a calculation. You can change
the variable to include a calculation or change an existing calculation by selecting the variable and
clicking the Create or Edit Calculation button. Make sure that all calculation references are resolved.

Save Variables
Select one or more variables to store the value in the raw data file for each group.
To specify a variable, click Edit List and select one or more variables.
•
Cyclic data is stored at the end of each cycle.
