I2C Trigger (Option)
I2C is a 2-wire serial bus used to connect the microcontroller and its peripheral
device. It is a bus standard widely used in the microelectronic communication control
field.
The I2C serial bus consists of SCL and SDA. Its transmission rate is determined by
SCL, and its transmission data is determined by SDA, as shown in the figure below.
MSO5000-E triggers on the start condition, restart, stop, missing acknowledgment,
specific device address, or data value. Besides, it can also trigger on the specific
device address and data values at the same time.

Trigger Type:
Press Type, and then rotate the multifunction knob to select "I2C". Press down
the knob to select the trigger type. Then, the current trigger setting information is
displayed at the upper-right corner of the screen, as shown in the figure below. You
can also press Type key continuously to select the trigger type or enable the touch
screen to tap the desired trigger type and select it.
Source Selection:
Press SCL and SDA to specify the signal sources of SCL and SDA respectively. They
can be set to CH1-CH2 or D0-D15. For details, refer to descriptions in "
Trigger
Source
". The current trigger source is displayed at the upper-right corner of the
screen.
Note: Only when we select the channel (that has been input with signals) as the
trigger source, can we obtain a stable trigger.
Trigger Condition:
Press When to select the desired trigger condition. Rotate the multifunction knob
to select the desired trigger condition, then press down the knob to select it. You
can also press When continuously or enable the touch screen to select it.
Start: triggers when SDA data transitions from high level to low level while SCL is
