I2C/SPI triggering and serial decode requires Option EMBD or the DSOX3EMBD

upgrade.

Setup for I2C Signals

C (Inter-IC bus) signals setup consists of connecting the oscilloscope to the

serial data (SDA) line and the serial clock (SCL) line and then specifying the input

signal threshold voltage levels.

To set up the oscilloscope to capture I

C signals, use the

Signals

softkey which

appears in the Serial Decode Menu:

Press

[Label]

to turn on labels.

Press

[Serial]

NOTE

Only one SPI serial bus can be decoded at a time.
