MSO7000X-AUDIO Audio Serial Bus Trigger and Analysis (I2S, LJ, RJ, TDM) Option
Overview
The MSO7000X-AUDIO adds audio serial bus triggering, decoding, and search for I2S, Left-Justified, Right-Justified, and TDM protocols to your MSO7000X Series oscilloscope — the standard digital audio interfaces between DACs, ADCs, codecs, and DSPs.
Designing audio hardware and tracking down clicks, pops, or dropouts? This option shows decoded audio sample values overlaid on clock and data waveforms.
Key Features
- Multi-Format Support — Decodes I2S, LJ, RJ, and TDM. Configurable word size (16/24/32-bit) and channel count.
- Sample-Level Triggering — Trigger on specific audio sample values or ranges — capture clipping, silence, or test tones.
- Real-Time Decoding — Decoded samples display aligned with BCLK, LRCLK/WS, and data for timing verification.
- Channel Identification — Labels left/right channels or TDM time slots for multi-channel debugging.
- Software License Activation — License key applied through the instrument menu. No hardware changes, no downtime — enter the key and start decoding.
When You Need This
DAC Interface Verification
Decode I2S data to verify sample values and check BCLK/LRCLK timing for data latching issues causing distortion.
Infotainment Debug
An amplifier clicks during source switching. Trigger on the TDM stream to identify invalid samples, clock glitches, or muting logic issues.
Compatible Instruments
This option is compatible with all MSO7000X Series oscilloscopes: MSO7104X (1 GHz) and MSO7204X (2 GHz).

Frequently Asked Questions
Should I buy this individually or get a bundle?
If you only need Audio (I2S/LJ/RJ/TDM), the individual license at $999 is the most economical. The BND bundle ($2,399) includes every protocol at the deepest discount.
How is this option activated?
You receive a license key after purchase. Enter the key in the instrument's menu under System → Options → Install. The capability is available immediately — no reboot, no hardware modification, no factory service required.
Is the license permanent or subscription-based?
All UNI-T software option licenses are permanent, one-time purchases. Once activated, the option remains available for the life of the instrument. No annual renewals or subscription fees.
