MSO5000HD-AUDIO

MSO5000HD-AUDIO – Audio Bus Protocol Decode Option (I²S / LJ / RJ / TDM)

🎧 Decode Digital Audio Signals with Confidence on the MSO5000HD

The UNI-T MSO5000HD Series oscilloscope offers exceptional 12-bit resolution, 1 GHz bandwidth, and deep protocol visibility—ideal for modern audio interface debugging. With the MSO5000HD-AUDIO optional license, you can unlock real-time decoding and triggering for a range of digital audio buses including:

• I²S (Inter-IC Sound)

• LJ (Left Justified)

• RJ (Right Justified)

• TDM (Time Division Multiplexed Audio)

These protocols are widely used in embedded audio systems, consumer electronics, automotive infotainment, and digital signal processing applications. This option gives engineers a direct view into their audio data at the bit, word, and channel levels—essential for resolving tricky timing or data alignment issues.

🔍 Key Capabilities

• Decode left/right channel audio data streams in real time

• Visualize word select (WS), serial clock (SCK), and data lines (SD) with fully synchronized analysis

• Trigger on specific word values, channel ID, or data anomalies

• Automatically build event tables for frame-by-frame review

• Display waveform overlays showing timing alignment and decode results simultaneously

🧠 Benefits of MSO5000HD-AUDIO

• Time-Correlated Debugging
  View decoded audio alongside analog measurements such as power ripple, noise, or amplifier distortion—ideal for root cause analysis.

• Accelerated Development
  Rapidly identify clock skew, bit slippage, or incorrect word formatting in early-stage hardware.

• Educational Clarity
  Show students or team members real-time audio frames mapped directly onto their waveforms, making abstract data formats more intuitive.

🛠️ Ideal Applications

• Audio codec debugging (I²S / TDM buses)

• Automotive digital audio system validation

• Smart speaker, headphone, or DSP development

• Educational labs in signal processing and embedded design

• Digital audio routing systems with high channel counts
