313User Manual 1335.5337.02 ─ 07
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.
13.1.1 Setup - general settings

Configuration settings are protocol-specific. They are described in the related chapters.
Make sure that the tab of the correct serial bus is selected.
