Rigol DS70000-AUDIOA - Audio Serial Bus Trigger and Analysis (I2S)

The RIGOL DS70000-AUDIOA offers audio serial bus trigger and analysis (I2S).

I2S Trigger (optional) With the I2S trigger, the oscilloscope searches for a specified data value and uses it as the trigger condition. You need to specify the serial clock line (SCLK, one pulse on the clock line is found once 1 bit of digital audio data is sent), the frame clock line (WS, used to switch the audio channel data), and the serial data line (SDA, used to transmit audio data represented in binary, 2's complement).
