31 :SBUS<n> Commands
• 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.
• CXPI triggering— lets you trigger on CXPI serial data.
• 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.
• 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.
• SPI (Serial Peripheral Interface) triggering— consists of connecting the oscilloscope
to a clock, data (MOSI or MISO), and framing signal. You can then trigger on a
data pattern during a specific framing period. The serial data string can be
specified to be from 4 to 64 bits long.
• UART/RS-232 triggering— lets you trigger on RS-232 serial data.
• SENT triggering— lets you trigger on SENT serial data.
• USB 2.0 triggering— lets you trigger on USB 2.0 serial data.
• USB PD triggering— lets you trigger on USB PD serial data.
Reporting the Setup
Use :SBUS<n>? to query setup information for the :SBUS<n> subsystem.
Return Format
The following is a sample response from the :SBUS1? query. In this case, the query
was issued following a *RST command.
:SBUS1:DISP 0;MODE IIC;:SBUS1:IIC:ASIZ BIT7;:SBUS1:IIC:TRIG:TYPE
STAR;QUAL EQU;:SBUS1:IIC:SOUR:CLOC CHAN1;DATA
CHAN2;:SBUS1:IIC:TRIG:PATT:ADDR -1;DATA -1;DATA2 -1
Two I2S buses or two SPI buses cannot be decoded on both SBUS1 and SBUS2 at the same
time.
