2Press the Signals softkey to display the I2C signals menu.
3Connect an oscilloscope channel to the SCL (serial clock) line
in the circuit under test, then set the SCL clock channel
softkey to that channel.
As you press the SCL softkey (or rotate the Entry knob on
mixed-signal oscilloscopes), the SCL label for the source
channel is automatically set and the channel you select is
shown in the upper-right corner of the display next to “I2C”.
Adjust the trigger level for the selected analog channel by
turning the Trigger Level knob. Press the D15 Thru D0 key and
select Thresholds to set the threshold level for digital
channels. The value of the trigger level or digital threshold is
displayed in the upper-right corner of the display.
4Choose 7-bit or 8-bit address size. Use 8-bit address size to
include the R/W bit as part of the address value, or choose
7-bit address size to exclude the R/W bit from the address
value.
5Connect an oscilloscope channel to the SDA (serial data) line
in the circuit under test, then set the SDA data channel
softkey to that channel.
As you press the SDA softkey (or rotate the Entry knob on
mixed-signal oscilloscopes), the SDA label for the source
channel is automatically set and the channel you select is
shown in the upper-right corner of the display next to “I2C”.
Adjust the trigger level for the selected analog channel by
turning the Trigger Level knob. Press the D15 Thru D0 key and
select Thresholds to set the threshold level for digital
channels. The value of the trigger level or digital threshold is
displayed in the upper-right corner of the display.
