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 648).
• 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.
• I2S (Inter- IC Sound or Integrated Interchip Sound bus) triggering—
consists of connecting the oscilloscope to the serial clock, word select,
and serial data lines, then triggering on a data value.
• 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.
NOTE
These commands are only valid on oscilloscope models when a serial decode option has
been licensed.
