MSO2000X-AUDIO – Digital Audio Protocol Decode Option

🎧 Decode I²S, LJ, RJ, and TDM Audio Interfaces

The MSO2000X-AUDIO license adds digital audio protocol decoding to your UNI-T MSO2000X Series oscilloscope. Supporting I²S (Inter-IC Sound), Left Justified (LJ), Right Justified (RJ), and TDM (Time-Division Multiplexing) formats, this option is ideal for analyzing audio data between DACs, codecs, DSPs, and embedded microcontrollers.

With this license enabled, the oscilloscope can trigger on audio word alignment, decode left/right channel data, and correlate timing and data integrity issues directly with physical-layer waveforms—making it a powerful debug tool for embedded audio system developers.

✅ Standard Serial Protocols Always Included

All MSO2000X Series models include built-in support for:

RS-232 / UART
I²C
SPI

🧩 Digital audio decoding is optional and requires the MSO2000X-AUDIO license.
