13.1 Basics of protocol analysis
Before you can analyze a serial signal, the bus has to be configured according to the
protocol and specifics of the signal. The configuration contains:
●
Assignment of the data and clock lines to the input channels
●
Logical thresholds
●
Protocol-specific settings
Serial data can be analyzed in several ways:
●
Triggering: You can trigger on various events that are typical for the selected proto-
col type, for example, on start and stop of messages, or on specified data patterns
in the message.
Triggering on a trigger event sequence is not supported, and holdoff settings are
not available.
●
Protocol decoding: The digitized signal data is displayed on the screen together
with the decoded content of the messages in readable form, and the decode
results are listed in a table.
●
Search on decoded signal data: For most serial protocols, you can find various
events in the decoded data. You can find the same events that you can trigger on,
and even many more, because several event types can be combined. Thus, you
get the results for the complete acquisition cycle.
