8.1.2 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:
●
Bus signal with combs, time-correlated to the input signals. The combs show the
values of the frames or words.
●
Decode results table. The table provides data values and time information of the
frames or words.
To decode the serial bus
1. In the "Bus" menu, enable "State".
The bus signal with combs is shown. The colors of the combs are protocol-specific
and described in the "Decode Results" chapters of the protocol description.
