Only available for CAN protocols if DBC file is loaded.
If disabled, only the message names are shown in the comb display of the decoded
data. If enabled, the signal labels are shown in addition.

9.1.2 Decode Results
When the configuration of the serial bus is complete, the instrument can decode the
signal. The decode results are displayed in two ways:
●
In "Scope" mode, the bus signal is shown as combs, together with the time-correla-
ted input signals. The combs show the address and data values.
●
In "Protocol" mode, detailed results are listed in a table. The table provides data
values and time information of the frames or words.
9.1.2.1 Decoded Signal in Scope Mode
To decode the serial bus
► In the "Bus" menu, enable "State".
The bus signal is shown in a comb display. The colors of the combs are protocol-
specific and described in the "Decode Results" chapters of the protocol description.
