Groups Tab

Use Groups in an A2L file to help organize Measurements and Characteristics into logical categories.

The Groups tab has a table to display all A2L file Groups and their properties.  Each row (below the 1st filtering row) defines a Group and each column is a property.  The default column configuration is shown in Figure 1.
