MSO3000X-AUDIO

MSO3000X-AUDIO – I²S / LJ / RJ / TDM Protocol Decode Option

🎧 Precision Audio Bus Decoding for Embedded and Automotive Applications

The MSO3000X-AUDIO unlock adds triggering and decoding for popular digital audio protocols—including I²S, Left Justified (LJ), Right Justified (RJ), and Time Division Multiplexing (TDM)—on your UNI-T MSO3000X Series oscilloscope. Whether you’re building car audio systems, integrating DSPs, or validating codec signals in consumer devices, this upgrade delivers reliable insights into serial audio communication.

Use it to verify channel alignment, bit depth, timing consistency, and data integrity across both simple and multichannel audio buses.

✅ Standard Protocols Included

All MSO3000X models include decoding for:

• RS-232 / UART

• I²C

• SPI

🧩 Digital audio decoding requires the MSO3000X-AUDIO unlock.
