How to measure full speed USB and I2S at the same time on LAP-F1

Описание: Stop wrestling with cross-protocol timing issues. This video demonstrates how to sync Full-Speed USB with I2S audio data using the LAP-F1, providing a complete view of your signal chain from packet to waveform.

Hardware Environment:
DUT: TI PCM2707 + USB Bridge Board.

Setup: Direct I2S pin soldering for precise signal acquisition.
Key Features Demonstrated:
Long-Time Record: Capture data for minutes or hours without missing transients.
Advanced Search: Locate specific USB packets or I2S data intervals instantly.
WAV Export: Save I2S packets as .wav files for external analysis in tools like Audacity.
Analog Waveform View: Visualize digital I2S data for intuitive debugging.

Quick Operation Steps:
Signal Prep: Solder I2S pins; connect USB via bridge board.
Configuration: Set Port A trigger voltage to 1.65V.
Capture: Enable "Long Time Record" and click Single Capture.
Analysis: Use Advanced Find to sync USB packets with I2S volume spikes.
Post-Processing: Use "Save As" to trim file size, then export I2S to .wav
