2.7.14 IIC Trigger
IIC (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 IIC signals, please refer to the following:
1. Press the [Trig Menu] button on the front panel to enter the Trigger system function
menu.
2. Press the Type softkey, then turn the Universal Knob to select IIC and push down
the knob to confirm.
3. Source Selection: Press SCL and SDA softkey, turn the Universal Knob to to specify
the data sources of SCL and SDA respectively. They can be set to CH1-CH4.
4. Press When softkey to set trigger condition. Select trigger condition “Start Bit”,
connect the SCL signal to CH1 and connect the SDA signal to CH2.
Press the corresponding Level softkey; then, turn the Trigger Level knob to set the
signal threshold voltage level.
• Data must be stable during the entire high clock cycle or it will be interpreted
as a start or stop condition (data transitioning while the clock is high).
