24 :SBUS<n> Commands
• 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 (with Option 232) — lets you trigger on RS-232 serial
data.
