MSO3000HD-AUDIO

MSO3000HD-AUDIO – I²S / LJ / RJ / TDM Protocol Decode Option

🎧 Decode Audio Bus Communication with Clarity and Confidence

The MSO3000HD-AUDIO unlock enables 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 MSO3000HD Series oscilloscope.

This option is ideal for engineers working on automotive infotainment systems, embedded voice interfaces, DSP development, or audio codec integration. Decode and verify high-resolution audio data streams directly at the physical layer—no need for separate logic analyzers or protocol analyzers.

✅ Standard Protocols (Included Without License)

All MSO3000HD scopes come standard with decoding for:

• RS-232 / UART

• I²C

• SPI

🧩 I²S, LJ, RJ, and TDM decoding requires the MSO3000HD-AUDIO unlock.

🔓 What You Unlock with MSO3000HD-AUDIO

🧠 Real-World Use Cases

✅ Infotainment System Debug

Verify that head units transmit properly formatted I²S streams to external amplifiers. Trigger on audio word alignment or bit clock irregularities.

✅ Microphone Array Integration

Use TDM decode to confirm correct slot mapping and sample sequencing in digital microphone arrays or voice-activated products.

✅ Embedded Audio Codec Development

Monitor Left/Right Justified or I²S streams to confirm signal timing and data content across BCLK, WS, and DATA lines.

✅ Audio Quality Assurance

Identify dropped frames, jitter, or incorrect sample widths that could degrade sound quality in car audio or consumer electronics.
