SCLK: sample the SDA on the clock rising edge or falling edge.
SDA: denote the data channel.
Press MATH ïƒ BUS1 ïƒ Decode to select "I2C" and turn the I2C decoding function
menu on.
If the current trigger type of the trigger system is I2C, press CopyTrig to copy the
current I2C trigger configurations (include the clock signal (SCL) and data signal
(SDA)) to the I2C decoding configurations. After that, you can still set the I2C
decoding parameters according to the introductions below.
Note: The copy function is only available when the current trigger type is "I2C";
otherwise, CopyTrig is not available.
1. SCLK Setting
Press SCLK to select any channel (CH1-CH4) as the clock channel.
Press SCLK to set the threshold of the clock channel.
