When the configuration of the serial bus is complete, the signal can be decoded:
1. In the "Bus" menu, enable "Decode".
2. In the "Display" menu, select the result display settings.
See Chapter 13.1.2, "Displaying decode results", on page 253.
3. In the "Bus Table" menu, enable the "Bus Table". Adjust the table settings.
See also: Chapter 13.1.3, "Bus table: decode results", on page 254
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.
The figure above shows a decoded Audio signal and the "Bus Table".
