8.2.2 I2C Configuration Settings
Access: "Bus" menu > "Bus Protocol" = "I2C" > "Config"
SCL, SDA
Set the input source of the data line (SDA) and clock line (SCL).
If option R&S RTH-B1 is installed, digital channels can also be used as source.
Remote command:
BUS:I2C:SCL:SOURce on page 375
BUS:I2C:SDA:SOURce on page 375
Thresholds, Technology, Find Level
Sets the threshold value for digitization of signals. If the signal value is higher than the
threshold, the signal state is high. Otherwise, the signal state is considered low.
You can select the threshold voltages for various types of integrated circuits in the
"Technology" list, or set a user-defined value in "Thresholds". You can also let the
instrument set the appropriate threshold using "Find Level".
Changing the thresholds in the bus configuration changes also the thresholds of ana-
log channels in the "Vertical" menu, or the thresholds of logic channels in the "Logic"
menu.
