OVERVIEW

DOCUMENTATION

UNI-T MSO8000HD-AUDIO | Audio Serial Bus Analysis Option (I²S, LJ, RJ, TDM)

Overview

The MSO8000HD-AUDIO option provides comprehensive analysis and decoding capabilities for digital audio communication protocols including I²S (Inter-IC Sound), Left Justified (LJ), Right Justified (RJ), and Time Division Multiplexed (TDM) formats. These protocols form the foundation of modern digital audio systems, from consumer electronics to professional audio equipment and automotive infotainment systems.

Essential for audio system development, validation, and troubleshooting, this option delivers real-time protocol decoding, audio data analysis, and comprehensive examination of timing relationships. Engineers can validate audio codec interfaces, debug digital audio processing chains, and ensure proper synchronization in multi-channel audio systems where timing precision directly impacts sound quality.

UNI-T MSO8000HD-AUDIO I²S Protocol Analysis

Inter-IC Sound (I²S) serves as the most widely used digital audio interface, connecting digital signal processors, audio codecs, and DACs in consumer and professional audio systems. The protocol's three-wire architecture—bit clock, word select, and serial data—requires precise timing relationships to maintain audio fidelity and prevent channel crosstalk or data corruption.

The MSO8000HD-AUDIO option provides complete I²S analysis including bit clock validation, word select timing verification, and serial data decoding. Engineers can monitor left/right channel separation, validate audio sample rates, and identify timing violations that could cause audio dropouts, clicks, or channel swapping. The real-time analysis capability enables immediate detection of interface issues during system development and production testing.

UNI-T MSO8000HD-AUDIO TDM and Multi-Channel Analysis

Time Division Multiplexed (TDM) audio interfaces enable transmission of multiple audio channels over a single serial data line, commonly used in automotive infotainment, professional audio mixing, and telecommunications applications. The complex timing relationships and channel slot assignments in TDM systems require sophisticated analysis to ensure proper audio routing and quality.

The AUDIO option provides comprehensive TDM analysis including slot timing validation, channel assignment verification, and multi-channel data decoding. Engineers can monitor up to 32 audio channels simultaneously, validate slot boundaries, and identify channel assignment errors that could cause audio to appear in wrong locations or create unwanted mixing effects. The analysis extends to Left/Right Justified formats, providing complete coverage of digital audio interface standards.
