Decode

Setup for I2C Signals / 285

I2C Triggering / 286

I2C Serial Decode / 290

I2C triggering and serial decode is available on DSOX1200-Series and

EDUX1052A/G oscilloscopes.

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 Analyze menu:

1 Press [Display] > Labels > Display to turn on labels.

2 Press the [Analyze] key.

3 Press Features; then, select Serial Bus.

4 Press Features again (or push the Entry knob) to enable the serial bus display.

5 Press the Mode softkey; then, select I2C.
