10.2.3 Reference for I²C
10.2.3.1 I²C Configuration
Make sure that the tab of the correct serial bus is selected on the left side.
See also: chapter 10.1.1, "Configuration - General Settings", on page 251.
SDA, SCL
Set the waveforms of the data line (SDA) and clock line (SCL). Waveform 1 of channel
signals, math waveforms, and reference waveforms can be used.
For triggering, both lines require channel waveforms. Do not combine a reference wave-
form with channel or math waveform because the time correlation of these waveforms
might differ.
SCPI command:
BUS<m>:I2C:SDA:SOURce on page 645
BUS<m>:I2C:SCL:SOURce on page 645
Threshold
Sets the threshold value for digitization of signals for each line. If the signal value on the
line is higher than the threshold, the signal state is high (1 or true for the boolean logic).
Otherwise, the signal state is considered low (0 or false) if the signal value is below the
threshold.
