The Teledyne LeCroy WS4KHD-AUDIO TD AudioBus trigger, decode, and graph bundle provides all the tools needed to properly analyze and debug digital audio buses and addresses the I2S, LJ, RJ, and TDM variations of the audio bus standard. It is for use with the WaveSurfer 4000HD Oscilloscope series.

Enables the unique View Audio feature that converts the digitally-encoded serial data audio signal into an analog waveform display. This provides an intuitive way to understand circuit problems causing clipping, glitches, and other anomalies in the audio circuit. It also helps show the effects of the audio signal before Digital Signal Processing (DSP). View Audio can be performed for up to four audio channels for conventional Left/Right audio, or home cinema applications (enabled by time division multiplexed audio buses).

Audiobus uses color-coded overlays on various sections of the protocol decode for an easy-to-understand visual display. It is intuitive to experienced audio engineers and especially useful for users new to the I2S, LJ, RJ, or TDM Audiobus standards. The decode information condenses or expands depending on the timebase/zoom ratio setting, simplifying both routine verification and complex troubleshooting. Choose to decode into Hex, Binary, Decimal, or dB formats.

The Audiobus trigger can be configured for I2S, LJ, or RJ variants. Powerful conditional triggering can be applied to either left or right channel data, while unique triggers like mute, clip and glitch help to isolate rare problems not easily detected by viewing decoded data alone.

Turn an oscilloscope into a protocol analyzer with the Table display of protocol information. Custom configure the Table to display only the desired information, and export Table data to an Excel file. Touch a message in the table and automatically zoom for detail. In all cases, the Table never obscures the waveform data.

Audiobus messages can be quickly located by searching on message or pattern. Pressing an arrow button advances the single zoomed message view one message to the right or left of the current message.
