📖 Student Help & Experimental Protocol Guide (Single Phone Mode) Dr APJ Abdul Kalam Zero-cost Research Lab

Step 1: Configure & Connect Connect your single smartphone to the PZT Transceiver patch (Audio Out to Actuator, Mic/Aux In to Sensor). Select your EMI sweep or wave burst parameters.

Step 2: Run Transceiver Click Run Simultaneous Transmit & Capture. The phone simultaneously emits the excitation signal and records the structural response stream in real-time.

Step 3: Unified Audit File Download the single garrf_transceiver_audit_log.csv file containing both emission metadata, captured reflection/transmission waveforms, and instant calculations.
