2
C Serial Bus Interface
The I
2
C bus is a 2 wire interface with a serial data line (SDA) and
serial clock line (SCLK). The I
2
C protocol supports 7 or 10 bit
addressing and multiple masters. The scope will trigger on any of
the following conditions: a start/stop condition, a restart, a missing
acknowledge message, Address, Data or Address&Data frames.
The I
2
C trigger can be configured for 7 or 10 bit addressing with the
option to ignore the R/W bit as well as triggering on a data value or
a specific address and direction (read or write or both).
Panel operation 1. Connect each of the bus signals (
SCLK
,
SDA
)
to one of the oscilloscope channels. Connect
the ground potential
to one of the probes’
ground clip.
