:SBUS<n> Commands
• IIC (Inter- IC bus) triggering— consists of connecting the oscilloscope
• LIN (Local Interconnect Network) triggering— will trigger on LIN sync
• SPI (Serial Peripheral Interface) triggering— consists of connecting
• UART/RS- 232 triggering (with Option 232) — lets you trigger on
• USB 2.0 triggering (with Option USF or Option U2H) — lets you trigger
Two I2S buses or two SPI buses cannot be decoded on both SBUS1 and SBUS2 at the same
