6. To refine the trigger settings, configure additional settings, which are available for
some trigger types.
For details, see Chapter 13.18.3.1, "SpaceWire trigger settings", on page 867.
13.18.4 SpaceWire decode results
When the configuration of the serial bus is complete, the signal can be decoded:
1. In the "Protocol" dialog > "Decode" tab, enable "Decode".
2. In the "Protocol" dialog > "Display" tab, select additional result display settings:
"Show decode table" and "Show binary signals".
For a description of the display settings, see also Chapter 13.1.3, "Display",
on page 515.
The instrument captures and decodes the signal according to the standard 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.
Example
The example in Figure 13-111 shows a decoded signal with ambiguous bits (the earli-
est, least significant, parity bit among all surviving tracks). In the honeycomb the
ambiguous bits are marked in pink. Additionally they are reflected in the result table.

The example in Figure 13-112 shows a decoded signal with existing parity errors. The
errors are marked with red on the honeycomb and reflected in the results table.
