I²C Electrical Validation

Use an oscilloscope to do I2C Electrical Validation to ensure that the I2C meets the defined specifications. It can be confirmed that the electrical characteristics of the signal to be tested meet the specifications after a long burn-in test. For protocol electrical validation

I2C Protocol electrical characteristic detection is usually divided into two types: vertical (voltage) and horizontal (time/phase).

Therefore, when using this function, you must first set the selected protocol and specifications, and then repeat the test to get the electrical characteristics test report. The test items will have different specifications and standards depending on the I2C Speed.
