Common Features of Serial Bus Signal Analysis Functions (/F1 to /F11 Options)
Analysis result display
Decoded information is displayed together with waveforms or in
list form.
Auto setup function
A threshold value, time axis scale, voltage axis scale and other
bus-specific parameters such as a bit rate and recessive level are
automatically detected. Trigger conditions are set based on the
detected result and decoded information is displayed.
(The type of a bus signal needs to be specified in advance.)
Search function
Search of all waveforms for a position that matches a pattern or
condition specified by data information.
Analysis result saving
function
Analysis list data can be saved to CSV-format files. Trend data can
be also saved for SENT signals.
