Introduction to
:SBUS<n>
Commands
The :SBUS subsystem commands control the serial decode bus viewing, mode,
and other options.
The following serial bus decode/trigger types are available (see ":TRIGger:MODE"
on page 580).
• CAN (Controller Area Network) triggering— will trigger on CAN version 2.0A and
2.0B signals. Setup consists of connecting the oscilloscope to a CAN signal.
Baud rate, signal source, and signal polarity, and type of data to trigger on can
be specified. You can trigger on CAN data and identifier patterns and you can
set the bit sample point.
• IIC (Inter-IC bus) triggering— consists of connecting the oscilloscope to the serial
data (SDA) line and the serial clock (SCL) line, then triggering on a stop/start
condition, a restart, a missing acknowledge, or on a read/write frame with a
specific device address and data value.
• LIN (Local Interconnect Network) triggering— will trigger on LIN sync break at the
beginning of a message frame.You can trigger on Sync Break, Frame IDs, or
Frame IDs and Data.
NOTE
These commands are only valid on oscilloscope models when a serial decode option has been
licensed. The CAN, LIN, and SPI serial decode and triggering options are available on the
DSOX1000-Series oscilloscope models only.
