3. In the "Bus Table" menu, enable the "Bus Table". Adjust the table settings.

The instrument captures and decodes the signal according to the protocol definition
and the configuration settings.
The color-coding of the various protocol sections and errors simplifies the interpretation
of the visual display. The decode information condenses or expands, depending on the
horizontal scale. Various data formats are available to show the result values.
