"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.
Examples
The example in USBPD protocol: decoded and binary signal shows a simulated
USBPD message. Among the long line of decoded frames, the zoom has selected a
"Data" frame.
Figure 13-105: USBPD protocol: decoded and binary signal
Green brackets [...] = Start and end of frame
Dark green field = Header
Light blue fields = CRC checksum
Orange fields = Data bits
The example in USBPD protocol: decoded and binary signal, and decode results
shows the same simulated USBPD message as in Figure 13-105, but with overlaid
decode results (upper table, showing frames) and decode results details (table below,
showing decoded fields of the selected frame).
