time, data direction, ID and ACK information in table format.

Press Event Table  Event Table to select “ON” (note that this operation is

only available when BusStatus is set to “ON”) to enter the decoding table

interface as shown in the figure below. If a USB storage device is currently

connected to the instrument, you can export the data table to the external USB

storage device in CSV format.

5. Error Expressions during Decoding

In I2C bus, the front part of each frame of data contains the address information

and blue patches are used to represent address ID. In the ID, “Write” is used to

represent writing address and “Read” is used to represent reading address.
