I2S (Inter-IC Sound, or Integrated Interchip Sound), is an electrical serial bus interface standard used for connecting digital audio devices together, such as compact disc, digital audio tape, digital sound processors, and digital TV sound. Traditional methods of debugging serial busses such as I2S includes manual bit counting. But this visual technique of counting “1’s” and “0’s” can be tedious and prone to errors, especially since I2S is typically formatted in a 2’s complement format.

Keysight Technologies’ serial bus options for the InfiniiVision oscilloscopes not only offers powerful triggering, but also provides unique hardware-accelerated decoding to help you debug audio designs with the I2S bus faster. With the industry’s fastest serial decode update rates, you can more easily find and debug random and intermittent errors and signal integrity problems that you could easily miss using other serial bus decode tools.
