I²S Electrical Validation
Use an oscilloscope for I²S electrical validation to ensure compliance with defined specifications. After an extended burn-in test, the oscilloscope confirms that the electrical characteristics of the signal meet the required standards.
Supported Models: TS3124V (4-channel DSO), MSO3124V (4-channel DSO + 16-channel LA)
