The content of the "Decode results" table in Figure 13-56 is described in Table 13-12:
Table 13-12: Content of the "Decode results" table
Column Description
Type Frame type
State Overall state of the frame: either OK or the relevant error condition (preamble,
length)
Start Start time of the frame
Stop Stop time of the frame
Destination Address Destination address of the frame
Source Address Source address of the frame
Type/Length The subprotocol (e.g. HTML, video, etc.) determines what meaning this field has.
Since the content of this data area is not decoded, the interpretation of this field is
ambivalent. It could either be the word type (specific for the subprotocol) or the
word length.
Data Values of the data bytes in a frame. The table shows a truncated version; to see all
the bytes in a separate data table, activate "Show details". The data format is
always hexadecimal.
CRC FrameCheck (Cyclic Redundancy Code, CRC)
Destination Symbol Translation (or symbolic label) of the destination address, if the label list is
enabled.
Source Symbol Translation (or symbolic label) of the source address, if the label list is enabled.
Number of Words Number of words in the frame
Bit rate Value of the bit rate
Data format
You can select various data formats for the values displayed in the decode table and in
the combs of the decoded signal.

Zooming on decoded results
The zoom functions allow you to analyze the decode results in more detail. If "Zoom
coupling" is enabled, the decode zoom and result table are synchronized; if you select
a row in the result table, this result is shown in the decode zoom.
For an introduction to zoom settings and setup, see:
