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.
