25 :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.
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
NOTE
Two I2S buses or two SPI buses cannot be decoded on both SBUS1 and SBUS2 at the same
time.
